However, doing the test right would require a run-time test, and that would make cross-compilation harder. Let us hope that IBM fixes the xlc bug, and also adds support for this kind of constant expression. In the meantime, this test will reject xlc, which is OK, since our stdbool.h substitute should suffice.

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The GNU General Public License is a free, copyleft license for software and other kinds of works. The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things. To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others. For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it. For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions. Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users. Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free. The precise terms and conditions for copying, distribution and modification follow. TERMS AND CONDITIONS 0. Definitions. "This License" refers to version 3 of the GNU General Public License. "Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks. "The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations. To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work. A "covered work" means either the unmodified Program or a work based on the Program. To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well. To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying. An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion. 1. Source Code. The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work. A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language. The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it. The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work. The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source. The Corresponding Source for a work in source code form is that same work. 2. Basic Permissions. All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law. You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you. Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary. 3. Protecting Users' Legal Rights From Anti-Circumvention Law. No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures. When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures. 4. Conveying Verbatim Copies. You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program. You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee. 5. Conveying Modified Source Versions. You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions: a) The work must carry prominent notices stating that you modified it, and giving a relevant date. b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices". c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it. d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so. A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate. 6. Conveying Non-Source Forms. You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways: a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange. b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge. c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b. d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements. e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d. A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work. A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product. "Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made. If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM). The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network. Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying. 7. Additional Terms. "Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions. When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission. Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms: a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or d) Limiting the use for publicity purposes of names of licensors or authors of the material; or e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors. All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying. If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms. Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way. 8. Termination. You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11). However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10. 9. Acceptance Not Required for Having Copies. You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so. 10. Automatic Licensing of Downstream Recipients. Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License. An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts. You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it. 11. Patents. A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version". A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License. Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version. In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party. If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid. If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it. A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007. Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law. 12. No Surrender of Others' Freedom. If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program. 13. Use with the GNU Affero General Public License. Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such. 14. Revised Versions of this License. The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation. If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program. Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version. 15. Disclaimer of Warranty. THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. Limitation of Liability. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 17. Interpretation of Sections 15 and 16. If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program. If not, see . Also add information on how to contact you by electronic and paper mail. If the program does terminal interaction, make it output a short notice like this when it starts in an interactive mode: Copyright (C) This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, your program's commands might be different; for a GUI interface, you would use an "about box". You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU GPL, see . The GNU General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License.

Installation Guide This article includes download, build, and installation instructions. Compiling from source URLs
Build prerequisites GCC C++ compiler

GCC version 3.2.3 with C++ support is known to build ALE successfully. Older versions of GCC may fail to compile some versions of ALE.

 Prerequisites for building on Windows

Successfully running the configuration script on Windows (e.g., for native builds) may require installation of Cygwin. For more information on Cygwin, see:

Alternatively, this package can be cross-compiled for Windows on a non-Windows architecture, provided that the appropriate cross-compilers and libraries are available.

 Extraction

Download the source archive file from the URL indicated in the section 'URLs', and invoke:

tar xzf cd

Invoking 'ls configure' afterward should reveal an executable script 'configure'. This script is used to determine the capabilities of the system that will run the software.

 Running configure

This package uses a configuration script, 'configure', generated by the GNU project build tools ("autotools"). For most cases, it should be sufficient to invoke:

./configure make make install

In cases where the defaults are not adequate, configuration options can be passed to the configuration script.

 Configuration options

Configuration options can be passed to the 'configure' script prior to build and installation, as:

./configure --config-option1 --config-option2 ... make make install

Options specific to this package are described in the following subsections. General configuration options are described in the file 'INSTALL' included in the source package.

ImageMagick Support

Enabling ImageMagick support allows ALE to make use of the file-handling capabilities of ImageMagick ( ). This includes reading and writing a variety of file formats, including, among many others, PNG and JPEG (two formats commonly used in web publishing) as well as common interchange formats such as PPM and TIFF. ImageMagick 6.0.6 is known to work with this version of ALE; certain older versions of ImageMagick may cause compile, link, or runtime errors. By default, support is automatically detected.

--with-imagemagick=auto Auto-detect ImageMagick support [default] --with-imagemagick=yes Enable ImageMagick support --with-imagemagick=no Disable ImageMagick support Color Data Precision

ALE's internal data structures store each color channel within a pixel as floating-point data; similarly, arithmetic operations on color channels are performed in floating point. The available data-type configurations are listed below, with typical data sizes indicated in parentheses.

--with-colors=single Use C++ 'float' data type (32-bit) [default] --with-colors=double Use C++ 'double' data type (64-bit) Coordinate Data Precision

In general, coordinate transformations used by ALE produce results outside of the set of integers; hence, coordinates are treated as floating-point data. The two available data-type configurations are listed below, with typical data sizes indicated in parentheses.

--with-coords=single Use C++ 'float' data type (32-bit) [default] --with-coords=double Use C++ 'double' data type (64-bit) Thread support

Threads can improve performance on multiprocessor machines. POSIX threads are currently supported.

--enable-threads=auto Auto-detect thread support. [default] --enable-threads=yes Enable thread support. --enable-threads=no Disable thread support. FFTW Support

This feature is required in order to use the --fl option; it also determines the approach to calculation of discrete Fourier transforms used by the Irani-Peleg renderer. For more information on FFTW, see http://fftw.org/.

--with-fftw3=auto Auto-detect FFTW3. [default] --with-fftw3=yes Use FFTW3 discrete Fourier transform. --with-fftw3=no Use built-in discrete Fourier transform. Enable --wmx

This build option is required in order to use the --wmx option. If --enable-wmx is specified, it is expected that fork() and execlp() calls are available.

--enable-wmx=auto Automatically detect whether to enable --wmx --enable-wmx=yes Enable --wmx --enable-wmx=no Do not enable --wmx Getsize

This build option is required to obtain additional output from --ui=tty. If TIOCGWINSZ is not defined in <sys/ioctl.h>, however, additional output will not be provided even if --enable-getsize is specified at build time.

--enable-getsize=auto Check for TIOCGWINSZ at build time. [default] --enable-getsize=yes Configure to attempt to use TIOCGWINSZ --enable-getsize=no Do not attempt to use TIOCGWINSZ Assertions

Finding bugs within ALE, or within custom modifications to ALE, can be simplified by enabling run-time assertions. These checks enforce conditions believed to be necessary or desirable for correct program operation. If a condition is not satisfied, ALE will abort and display a message indicating the failed assertion.

--enable-assertions Enable assertions. [default] --disable-assertions Disable assertions. Cross-compilation

For cross-compilation, it may be necessary to specify both host and build machine types, using the configure --host and --build options. For more information on these options, see the file 'INSTALL' in the source package.

 Further details

General operation of the configure script is described in more detail in the file 'INSTALL' in the source package.

  • Reduce memory usage in Irani-Peleg and 3D renderers
  • Add new PSF options for convolution and scalar multiplication
  • Revise the 3D scene reconstruction algorithm
ALE is an image-processing program used for tasks such as super-resolution, deblurring, noise reduction, and anti-aliasing. Its principle of operation is synthetic capture, combining multiple inputs representing the same scene. This release fixes exclusion region and alignment bugs, adds device support for the Canon 300D SLR, and incorporates an experimental framework for reconstruction of 3D scenes.
  • Incorporate changes from 0.7.1 patches
  • Add a device configuration for the Canon EOS 300D (Digital Rebel)
  • Incorporate an approach to 3D reconstruction. (Does not work yet.)
  • Adds an option for establishing a minimum overlap area for global searches
  • Adds a rudimentary test suite.
  • Allows each perturbation bound to be specified as a percentage of the smallest image dimension (useful for large images?).
  • Fixes bugs in exclusion region handlers.
  • Fixes bugs in alignment failure handlers.
  • Avoids superfluously large undefined regions.
  • Adds experimental options for refining perturbation.
This release fixes alignment bugs, adds a global search option, and adds support for the OmniView OV7620 sensor.
  • Add linear PSF for OV7620
  • Add option to concatenate help pages
  • Fix VISP segfault
  • Incorporate changes from 0.7.0-patch1
The default PSF for the OV7620 can be a bit noisy. As an alternative, box=1.3+box=1.8 also works well in some cases, and is less noisy.
  • Fixes alignment bugs.
  • Adds a global search option.
  • Adds support for ov7620 in raw, linear mode.
The ov7620 device option expects that the 7620 be in raw, linear mode, and that clamping be turned on. These features may not be accessible using standard drivers. This release updates the renderer to support a variety of filters, including sinc and Lanczos, and adds new options for excluding image regions and processing video frames. Merging and drizzling renderers now operate in linear colorspace, and the Irani-Peleg renderer has been extended to handle convolutions in both linear colorspace (e.g. lens blur) and non-linear colorspace (e.g. some types of in-camera sharpening). New options in this release include certainty weighting and exposure registration. Changes in this release include optional support for 16-bit color channels and built-in support for all PPM file types. Also, a user manual and an updated technical description are now available. [This release was, and remains (as of Sep 2006), the most advanced version storing pixels as integer values (rather than as floating-point values). As integer values may be more suitable for certain applications, integer-valued functions may be re-introduced, possibly as library code, in the future. 19-Sep-2006] ALE is a program that can render high-fidelity images of real scenes by aligning and combining many similar images from a camera or scanner. The correct similarity between images is roughly that achieved by a somewhat unsteady hand holding a camera. Alignment following has been modified to support multiple-pass alignment of panoramic image mosaics. Other changes in this release include code cleanup and documentation updates. The Monte Carlo alignment algorithm has been modified, and may now offer better alignment for small sample sizes. Also, the Irani-Peleg renderer now writes output after each iteration when incremental output is enabled. Other changes include a bugfix in Euclidean alignment, a new option for configuring the level of detail, and a new independent constraint for rotational perturbation. Support for device-specific projection functions and various bugfixes have been added to the Irani-Peleg renderer. Also, a new option has been added that may be useful for video stabilization applications. This release fixes bugs in drizzling and post-processing. The following combinations should now work as expected: drizzling in combination with scaling and Irani-Peleg image reconstruction in combination with high-frequency enhancement. This release resolves a number of minor alignment bugs. The PPM file handler has been updated to open files in binary mode, resolving a serious bug under Windows. Also, the percentage of pixels used in Monte Carlo alignment now more closely matches user specifications in typical cases. A Monte Carlo alignment option has been added, which may reduce alignment time. An option to disable incremental file output has also been added. An iterative image reconstruction renderer has been added, and the PPM file handler has been updated to correctly handle PPM header comments. Increased spatial extents, drizzling, and new alignment options have been added in this release. A bugfix from the Debian ALE package version 0.4.0-1 has been merged. Without this fix, an assertion failure can occur when ImageMagick support is enabled.
  • The original Debian fix was implemented by Debian package maintainer Nick Rusnov.
A general scaling option has been added, and the high-frequency enhancement filter now works near image boundaries. A match summary was added to the program's output, comments in transformation file output were made more helpful, and an experimental high-frequency enhancement option was added. (This release appears to have been superseded by 0.3.2.) New options in this release facilitate writing final alignment transformations to a file, reading initial alignment transformations from a file, and setting an upper boundary on the correction step size used in alignment. General projective transformations can now be used in image alignment. A new file handler has been added to read and write JPEG, PNG, and other image formats using the ImageMagick C API. The default PPM-only file handler now deals with certain file errors more gracefully.
  • Translation of file formats using ImageMagick was suggested by Nick Rusnov.
In this version, a scaling bug that caused corruption of boundary pixels has been fixed. Also, the alignment algorithm has been modified to use reduced detail for coarse alignment steps. The image alignment algorithm has been updated.

Initial release

ALE aligns and merges several similar images from a digitizing device (such as a digital camera or scanner) into a single image. This may have the effect of producing a relatively alias-free image (sometimes called "anti-aliasing").

Change log This article contains detailed change information for each release. Change 1 Change 2 Change 3 0.8.5 (Prerelease) Documentation
  • Migrate documentation to a modified DocBook format.
  • Revise README for autotools build and installation.
  • Add file 'TODO', containing a tentative list of future versions and features.
  • Add AUTHORS file, in accordance with the autotools packaging standards.
  • Revise Changelog name to autotools-recognized ChangeLog
  • Add NEWS file containing summary announcement text, including mailing list and Freshmeat announcements for versions through 0.8.4. This file is required by autotools when not running in --foreign mode.
Configuration
  • Add autotools-based configuration, build, and installation facilities, replacing the earlier Makefile-based configuration and build process.
Command-line interface
  • Modify command-line interface to accept certain scope operators, and to increase uniformity of syntax.
Image constraints
  • Add options --f{ex,crop} for frame-coordinate exclusion regions.
3D Rendering
  • In d3::scene, always use filler spaces when --pc all is specified.
Source code organization
  • Move input interface details, including option handling, messages, and help information, to the ui/ subdirectory.
0.8.4 2006-May-14 Packaging
  • Fix build error noted by Gregory Maxwell and re-tag version.
Documentation
  • Add dates to the Changelog, using dates in comments in the download page on the website for versions prior to 0.8.0, and using dates from the darcs repository for versions 0.8.0 and later.
Command-line interface
  • Add fine-grain UI updates for 3D operations when using ui=tty. Reduce tty UI status update frequency to at most once per second.
3D Rendering
  • Add support for synthetic focus via the --focus option, including focus with horizontal and vertical tilt. Adding simulated focus effects, including tilted and swung focal planes, was suggested by Gregory Maxwell.
  • Add support for filtering 3D output with --3d-filter. This is now the default behavior. Add an option --3d-chain for selecting the filter chain used for 3D output. (See --hl and --hq for details.)
  • Interpolate to generate smooth 3D depth output.
3D Models
  • Modify --3dpx to affect scene geometry rather than rendered pixels. In certain cases, this change should allow removal of objects close to the camera, hence revealing objects further away.
  • Add decimation options --di-upper, --di-lower, and --do-try for reducing the complexity of 3D scene geometry, hence reducing the number of operations required for occupancy updating.
  • Fix dimension comparison bug in d3::space::traverse::get_next_split().
  • Implement an experimental approach to 3D subspace candidate selection; this seems to perform poorly in most cases due to parallax effects. See the source code for details. (Option --subspace-traverse)
  • Add adaptive weight decomposition to 3D occupancy algorithms.
  • Move low-level code concerning scale and level-of-detail from d3::scene to d3::pt.
  • Move code concerning the nature of space from d3::scene to d3::space.
  • Remove older 3D rendering code.
Scripts
  • Add a script 'transform' for applying an inverse projective transformation. Recalculation of transformations was suggested by Rob Stewart (ALE mailing list message, 2005-Dec-28).
Undocumented options
  • Add to the Makefile a HASH_MAP option that can be used to assign the 3D spatial info structure a hash map type instead of the standard STL map type. As this is likely to break things, it is currently undocumented. HASH_MAP=GNU seems to compile with g++ 4.0.x but has not otherwise been tested.
0.8.3 2005-Dec-23 Rendering
  • Add an option --def-nn to allow definition of pixels in output images to take values from neighboring pixels within a certain radius, in cases where they would not otherwise be defined.
3D Models Stereoscopy
  • Add option --pc to specify which pairwise comparisons should be performed.
  • Add option --pa to set the number of point candidates accepted for each pair of cameras (pairwise ambiguity). The default of 3 preserves existing default behavior.
  • Add option --tcem for scoring point candidates by third-camera views. The default of 0 preserves existing default behavior.
Geometry
  • Add option --3dpx to specify 3D regions to exclude during final rendering, using a single depth for each pixel in each frame of rendered output. (Evaluates at the depth used in depth-rendering.)
  • Add --et option to specify encounter thresholds.
  • Modify representation of 3D subspaces so that refined subspaces are roughly cubical, and to allow refinements at multiple resolutions.
  • Clean up d3::scene to remove triangle-mesh code.
Occupancy
  • Fix bugs in 3D color and occupancy updating caused by bounding box miscalculation.
  • Add option --oui for determining occupancy update iterations. The new default is 10, halving the previous default of 20.
0.8.2 2005-Nov-22 Image files
  • Add magical file 'dump:' for listing color values numerically to stderr.
3D Models
  • Transition from a subdivisible triangle model to a subdivisible space model, using a rudimentary implementation of Hans Moravec's notion of occupancy.
  • Add support for view and depth output from arbitrary cameras.
  • Add clipping plane options for 3D modeling.
Control points
  • Fix various bugs in control-point alignment reported by Gregory Maxwell.
0.8.1 2005-May-6 Build
  • Fix enumerator compile bugs noted by Gregory Maxwell and Tom Holroyd to cause compilation failure under GCC 3.4.
Defaults
  • Modify --q1 to use median-value incremental rendering.
Rendering
  • Add support for median-value incremental and Irani-Peleg rendering. Using a statistic other than the mean was suggested by Scott Scriven as a means of eliminating non-uniform artifacts. Using the median seems to improve performance on Scott Scriven's example sequences, as well as on the scaled output of fine:sinc*lanc for sparse inputs.
Exposure
  • Add a color adjustment option --exp-mult=.
Control points
  • Add support for using control points in 2D and 3D alignment, as well as in 3D model construction. New options include '--gs points', '--cpf-load=', '--cpp-upper=', '--cpp-lower=', '--va-upper=', and '--st'.
Transformation data files
  • Add average magnitude comments to transformation data file output.
3D Models
  • For 3D scene reconstruction, use a new unified surface model in place of the depth-based multi-model approach used in 0.8.0. The new model is adjusted on the basis of edge, angle, and color measures.
Scripts
  • Move ale-psf-calibrate to a new scripts directory.
0.8.0 2005-Jan-12 Command-line interface
  • Add user interface options --ui=stream and --ui=tty. The latter includes more detailed status output when terminal width information can be obtained (esp. when IOCTL=1 is set at compile time), and is the new default.
Exclusion regions
  • Add --crop argument, which excludes the spatial complement of a specified area over a specified set of frames. Gregory Maxwell notes several advantages of internal over external crops, including preserving knowledge of position in the uncropped frame, which among other benefits allows natural handling of Bayer patterns.
  • Modify rx_parameters in d2/render.h to use the ale_pos data type instead of int. This should allow exclusion regions to be calculated more accurately.
Image files
  • Add support for PPM with extended attributes (EPPM). Attributes handled specially include black level, shutter speed, aperture, and ISO (or gain).
Exposure
  • Add a flag --exp-meta-only which causes tonal registration to be performed only on the basis of exposure metadata (e.g., data encoded as EPPM extended attributes). This approach was suggested by Gregory Maxwell.
  • Fix an index variable bug in d2::image_bayer_ale_real::trigger().
  • Modify d2::exposure one-sided certainty so that the 'one-sided' condition only applies to bright (>50%) areas. Applying it to dark areas has no clear benefit, and an experiment by Gregory Maxwell demonstrates that doing so can exacerbate noise.
Alignment
  • Modify euclidean alignment so that perturb-upper and perturb-lower apply to rotational arclength.
  • Modify d2::align to use unscaled input images when the scale factor is larger than 1.0, or when a scaled_filter interpolant is being used.
  • Modify d2::align::set_exposure_ratio() so that alignment weights and certainty values are taken into consideration.
  • Add a --cw option to weight alignment error by certainty values, as suggested by Gregory Maxwell. This allows the contributions of pixels at maxval to be diminished, which can increase alignment success in certain cases.
Rendering Scale
  • Modify d2::image::scale() to allow scale factors in the interval (0, 1), and modify the command-line interface and help text to reflect this change. --scale= now accepts all finite positive values.
Incremental
  • Replace functions d2::incremental::{increase,decrease}_extents() with new functions that take exclusion regions into account. The new functions should also fix a boundary-calculation bug reported by Gregory Maxwell.
Irani-Peleg
  • Set image offsets in d2/render/combine.h. This allows Irani-Peleg rendering to work with --crop when the default rendering chain includes more than one rendering invariant.
  • Perform Irani-Peleg updating separately by channel instead of using vector operations. This allows divide-by-zero and other conditions to be localized to particular channels.
  • Modify the Irani-Peleg renderer to use estimate-based certainty. This seems to improve noise characteristics significantly.
  • Modify d2::render::ipc::_ip_frame_correct() so that exposure re-estimation uses a ratio of weighted sums instead of a weighted average of ratios.
  • Modify d2/render/ipc.h to handle exclusion regions more effectively.
Transformation data files
  • Write the results of tonal registration as a comment in the transformation data file.
3D Models
  • Add experimental cost calculation routines to d3/scene.h.
Source code organization
  • Move certain user interface elements to the source subdirectory ui/.
0.7.3 2004-Dec-1 3D Models o Add incremental 3D reconstruction output. Command-line interface o Remove the reference to a non-existent web page in unsupported::fornow(). Rendering Should the --bayer option be moved to another section? o Allow device-specific bayer patterns to be overridden by the --bayer option. 3D Models o Add an option for explicitly setting the camera view angle. Make the default view angle 43.7 degrees. o Implement optimizations that reduce the memory footprint when 3D options are used. o Modify the 3D cost reduction algorithm. The new algorithm seems to offer better results than the old in cases tested thus far, and does not require that spatial extension be enabled. o Add support for the Canon 300D with a 50mm f/1.4 lens (specifying view angle), as well as experimental support for the 50mm f/1.4 lens at 1.4 (specifying a linear PSF). Also add support for 50mm f/1.8 and 85mm f/1.8 lenses, specifying view angles as specified in the chart at http://www.acapixus.dk/photography/angle_of_view.htm o Don't output final data when --psf-match is specified. Doing so would be useless anyway, and apparently causes a segfault. o For cases where --psf-match is specified, modify the exposure settings for the final input image (i.e., reference image) so that default exposure is used, and modify the bayer pattern settings so that no bayer pattern is used. (The first of these modifications requires changes in the way that the array of input exposures is stored.) o Optionally (when OPTIMIZATIONS == 1) use the output of the default rendering chain directly as the Irani-Peleg initial approximation, instead of copying it. o Add support for PSF convolution and scalar multiplication. o Move all PSF parsing logic to a new file: d2/render/psf/psf_parse.h o Modify help argument processing so that several help arguments can be specified at a time. Change the usage text to reflect this. o Fix concatenated help output; outputs from all help options are now represented. (3D help had been omitted in 0.7.2.) o Add a check to ensure that at most one --q* option is specified. The issue of multiple --q* options being specified was raised on the ALE mailing list by Viktors Rotanovs. As there is currently no support for this, generating an error message is appropriate.
ale-0.9.0.3/doc/package/changelog/index.in0000644000175000017500000012622011164421407020377 0ustar dhilvertdhilvertV 0.9.0.3 2009-Mar-31 o Revise --version to include ImageMagick library information. o Add ditz issue database and package document BUG-REPORTING. o Refine warnings for 8-bit output when --16bpc (incl. default). o Fix --16bpc default behavior. o Fixed serious memory leak in alignment code, and less serious leaks. V 0.9.0.2 2008-Nov-05 o Fix 'exec -a' bashism in ale script, after this was reported by Mihai Varzaru as being broken in Ubuntu 8.10. o Update documentation makefile for better links compatibility. V 0.9.0.1 2008-Jun-13 o Use a pager (e.g., less) when displaying help. o Add a man page, at the recommendation of Debian developer Ruben Molina. The man page structure roughly follows that of Debian Iceweasel, GNU tar, and the earlier ALE manual page for Debian by Nick Rusnov and Ruben Molina. o Add new algorithms for pixel assignment in multi-alignment, including filling, least-size local selection, and global-best selection. o Fix various multi-alignment bugs, including a bug causing increased computational complexity for rendering, as well as offset and scaling bugs. o Modify --lod-max to --lod-preferred, add a dimension restriction --min-dimension on level-of-detail, and make --lod-preferred=-3 and --min-dimension=10 default. o Revise DejaGNU test suite for current option syntax, so that "make check" now runs all tests. o Do not attempt to handle --trans-{save,load} arguments as images in the ale wrapper script. o Add include to ui/ui.h in an attempt to resolve Debian bug #482765, reported by Marc Brockschmidt and noted by Ruben Molina. o Include more information about scale cluster structures in the logging ui. o Add tonal registration by element to multi-alignment code. o Add a minimum average certainty for registration of multi-alignment elements. o Modify ale script to tally thread statistics when the environment variable ALE_COUNT_THREADS is set non-zero. V 0.9.0 2008-Apr-14 o Add skeletal web documentation to the documentation tree, in doc/web, and revise this to consolidate more information on the front page. o Implement an alignment technique allowing multiple alignments for a single frame. Handling parts of a frame separately to resolve alignment issues (but using match thresholding to discard regions instead of using multiple alignments) was suggested by Rob Stewart. o Add --resident parameter, allowing explicit allocation of backing store for (e.g., large) image data structures. o Check for NaN in linearization and unlinearization in exposure_default, as a possible fix for a segmentation fault reported by Bret Towe. V 0.8.11 2007-Nov-03 o Revise certain code for improved execution speed, including disabling certain assertions and reducing calls to pow(). o Replace geometric-mean filtering of weight values with minimum-value filtering, reducing calls to pow(). o Add fixed-point data types selectable at configuration time for coordinate and color data, hence improving speed on certain embedded platforms. Use on phones was suggested by Wen Guihua. o Revise incremental rendering code to store color values unnormalized by weights. o Revise multi-alignment options for the currently-considered implementation. o Eliminate NaN propagation that could lead to alignment failure in certain cases, perhaps causing an alignment bug reported in earlier versions by Gregory Maxwell. V 0.8.10.1 2007-Oct-04 o Change 'char *' referencing string literals to 'const char *'. o Set perturbation multipliers to 1 in cases of a non-finite value. V 0.8.10 2007-Oct-02 o Add threading for d2::image::*scale_by_half() functions. o Always rescale transformations for full detail after alignment is complete. o Make --lod-max=-4 default. o Make default --dchain auto:triangle:2,fine:box:1,triangle:2, which should produce better output during re-filtering than the previous default. o Revise re-filtering operation to use as a filter scale the distance between nearest defined points in opposite axis-centered cones about the point to be filtered. o Update scale cluster structures and interpolation routines used in alignment for calculating and storing certainty and weights; in particular, certainty of the input frame is now pre-calculated for multiple levels of detail. o Add currently-unused skeletal code for non-linear level of detail calculations. o Revise Monte-carlo value to use a single static default, removing dynamic behavior and certain associated support code, and applying the sampling rate in a uniform manner to all levels of detail and all tonal and spatial registration algorithms. o Fix error in level-of-detail accounting in alignment code. o Replace references to math.h with references to ale_math.h. V 0.8.9.1 2007-Aug-31 o Attempt to resolve certain 'always true' warnings reported by Marius Schamschula on Mac OS 10.3.9 (PPC). o Add macros for isinf() and isnan() in an attempt to resolve build failures reported by Marius Schamschula on Mac OS 10.3.9 (PPC). o Resolve certain build errors occuring when configuring --disable-threads, or when threads are unavailable. o Remove instrumentation writing to 'lsimulated.png'. V 0.8.9 2007-Aug-25 o Set new defaults for --ips, --dchain, and --3d-dchain, and remove --q* o Add rendering chain scaled sampling filter type auto:, implementing re-filtering, with rough automatic filter size determination. o Add an abstract domain decomposition threading class. o Revise Irani-Peleg code for reduced memory and cpu use. o Attempt to fix exclusion region handling after a bug report by Gregory Maxwell; other issues may remain. o Fix handling of --ip-{mean,median}, resolving a bug noted by Gregory Maxwell. o Add wrapper script 'ale' for handling raw files and extracting Exif metadata. o Allow any match when the threshold specified is neither positive nor zero. o Update license to GPLv3. o Various rendering bugfixes. V 0.8.8.1 2007-May-18 /build o Disable d2::gauss::cutoff definition after a build failure reported by Marius Schamschula on an Intel Mac running 10.4.9 (gcc 4.0.0?). V 0.8.8 2007-May-15 o Include an incomplete implementation for multiple alignment region handling. o Make --16bpc default. o Add extents calculation to d2::render::ipc to limit the area examined during exposure re-estimation. o Provide a new cache of fixed size for input images, defaulting to 256MB, adjustable via the --cache option. o Add error statistics for calculating center of rotation and perturbation size for alignment. o Add loop avoidance for dynamic monte carlo alignment. o Reduce --mcd-removal default to 10. o Use synchronized instead of unsynchronized dynamic monte carlo removal checks. o Disable --follow in the non-default case when perturbation size is zero. o Make --no-inc default. o Add 'defaults' global search option, and make this option default. o Modify --gs-mo to allow specification as a percentage, and make 67% default. o Add user interface options --ui=log and --ui=quiet, with greater and lesser verbosity, respectively. o Modify black level handling to always use linear values. o Increase default barrel distortion multiplier and rate maximum to 2.0 and 8.0, respectively. o Revise ordering of ui_tty status output so that more informative fields occur earlier in the string. o Modify numerical formatting of certain UI elements to preserve constancy of field locations in typical cases. o Add Gaussian PSF. (HJ Hornbeck) o Recalculate diff statistics after increasing the mc parameter in dynamic monte carlo alignment. o Update Nikon D50 PSF. (HJ Hornbeck) o Add UI update thread, in cases where threads are available. o Allow file-scoped --gs and --gs-mo options. o Ignore fex regions for nex SSFEs, resolving a bug noted by Gregory Maxwell. o Add --black option for specifying black level as a fraction of saturation. o Add --ev option for specifying ISO100-equivalent EV. o Add breakdown of profiling information by perturbation size for local alignment. V 0.8.7 2007-Mar-04 o Add a weight-limiting option to the Irani-Peleg renderer. o Add incremental renderer mean invariant avgf:: weight-limited to initial values. o Modify d2::image::defined_scale_by_half() to use a geometric mean, so that alignment at reduced level of detail will still work at larger reductions when using non-zero certainty. V 0.8.6 2007-Feb-17 o In d2::align, use rotation about the frame center as an alternative in cases where the sampling centroid is undefined. o Modify d2::point::{neg,pos}inf() assertions to allow for isinf() implementations returning any non-zero value for any infinity. o Re-adjust exposure in Irani-Peleg even when no non-linear stage is present. o Adjust the default pixel definition threshold to account for the certainty floor. o Use a rudimentary, single-pass estimate-based certainty approach for incremental rendering. o When --cx is positive, use only certainty calculated from the simulated scene for estimating tonal registration in Irani-Peleg passes. o Remove --qr default setting, as certainty and range-extension now have established general defaults. o Change --cx to 1 by default. Change --exp-extend to be disabled by default. Remove these flags from default settings. o Update driver names to omit file type qualifiers, according to the convention used in HJ Hornbeck's Nikon D50 device configuration patch. o Add Nikon D50 device configuration. (HJ Hornbeck) o Update default settings according to time and image quality test results. fine:triangle:2, gauss:0.75, and combinations of these filters were suggested by HJ Hornbeck. o Revise incremental renderer to store unnormalized values, for better handling of small weights, and eliminate the minimum contribution weight. o Add inlining and pre-calculation to Irani-Peleg. (HJ Hornbeck) o Add gaussian sampling filter. (HJ Hornbeck) V 0.8.5 2007-Jan-19 o Remove binaries and documentation sections from the readme, and prune non-package documentation for source distributions. o Make the --follow alignment option default. o Add help text for argument scope. o Modify rotational alignment search to rotate about the centroid of the sample region. o Revert 3D code to experimental status due to poor handling of real image sets. o Modify 3D code for slightly better handling of real image sets. V 0.8.5-pre3 2006-Nov-03 /alignment o Fix a potential nondeterminism bug due to undefined seed bits in the random number generator. (Fixes certain alignment failures.) / o Modify default settings using Irani-Peleg rendering to use the triangle:2 incremental rendering chain. o Add dynamic monte carlo alignment, and make this default. o Correct --exp-mult arg count. (Gregory Maxwell) o Allow file-scoped use of --perturb-upper. V 0.8.5-pre2 2006-Oct-25 o Modify d2::image::scale() to correctly handle offsets for scale factors other than negative powers of two. o Reformat most help text to fit a 79 column screen. o Add option --profile to measure elapsed real time for 2D alignment and rendering operations. o Add support for POSIX threads to 2D alignment and rendering code. (Adding multithreading support was first suggested by Jody (Joe) Harris. Testing of multithreaded code on multiprocessor hardware was done by Gregory Maxwell.) V 0.8.5-pre1 2006-Oct-16 o Incorporate all existing ALE documentation within the source tree, and license under GPL. Begin migration of documentation, including package documentation files, to a more flexible format. o Modify ui_tty for correct operation under Hurd and DragonFly consoles. o Revise README for autotools build and installation. o Add file 'TODO', containing a to-do list for future releases. o Add AUTHORS file, in accordance with the autotools packaging standards. o Revise Changelog name to autotools-approved ChangeLog o Add NEWS file containing mailing list and Freshmeat announcement text for versions through 0.8.4. This file is required by autotools. o Add options --f{ex,crop} for frame-coordinate exclusion regions. o Add autotools-based configuration, build, and installation facilities, replacing the earlier Makefile-based configuration and build process. o Modify --mc to be a file-scoped option. o Modify command-line interface to accept certain scope operators, and to increase uniformity of syntax. o Move input interface details, including option handling, messages, and help information, to the ui/ subdirectory. o In d3::scene, always use filler spaces when --pc all is specified. V 0.8.4 2006-May-14 o Fix build error noted by Gregory Maxwell and re-tag version. o Add fine-grain UI updates for 3D operations when using ui=tty. Reduce tty UI status update frequency to at most once per second. o Modify --3dpx to affect scene geometry rather than rendered pixels. In certain cases, this change should allow removal of objects close to the camera, hence revealing objects further away. o Add to the Makefile a HASH_MAP option that can be used to assign the 3D spatial info structure a hash map type instead of the standard STL map type. As this is likely to break things, it is currently undocumented. HASH_MAP=GNU seems to compile with g++ 4.0.x but has not otherwise been tested. o Add support for synthetic focus via the --focus option, including focus with horizontal and vertical tilt. Adding simulated focus effects, including tilted and swung focal planes, was suggested by Gregory Maxwell. o Add support for filtering 3D output with --3d-filter. This is now the default behavior. Add an option --3d-chain for selecting the filter chain used for 3D output. (See --hl and --hq for details.) o Fix dimension comparison bug in d3::space::traverse::get_next_split(). o Implement an experimental approach to 3D subspace candidate selection; this seems to perform poorly in most cases due to parallax effects. See the source code for details. (Option --subspace-traverse) o Add adaptive weight decomposition to 3D occupancy algorithms. o Move low-level code concerning scale and level-of-detail from d3::scene to d3::pt. o Move code concerning the nature of space from d3::scene to d3::space. o Interpolate to generate smooth 3D depth output. o Remove older 3D rendering code. o Add decimation options --di-upper, --di-lower, and --do-try for reducing the complexity of 3D scene geometry, hence reducing the number of operations required for occupancy updating. o Add a script 'transform' for applying an inverse projective transformation. Recalculation of transformations was suggested by Rob Stewart (ALE mailing list message, 2005-Dec-28). o Add dates to the Changelog, using dates in comments in the download page on the website for versions prior to 0.8.0, and using dates from the darcs repository for versions 0.8.0 and later. V 0.8.3 2005-Dec-23 o Add option --3dpx to specify 3D regions to exclude during final rendering, using a single depth for each pixel in each frame of rendered output. (Evaluates at the depth used in depth-rendering.) o Add option --pc to specify which pairwise comparisons should be performed. o Add --et option to specify encounter thresholds. o Clean up d3::scene to remove triangle-mesh code. o Add an option --def-nn to allow definition of pixels in output images to take values from neighboring pixels within a certain radius, in cases where they would not otherwise be defined. o Modify representation of 3D subspaces so that refined subspaces are roughly cubical, and to allow refinements at multiple resolutions. o Fix bugs in 3D color and occupancy updating caused by bounding box miscalculation. o Add option --pa to set the number of point candidates accepted for each pair of cameras (pairwise ambiguity). The default of 3 preserves existing default behavior. o Add option --oui for determining occupancy update iterations. The new default is 10, halving the previous default of 20. o Add option --tcem for scoring point candidates by third-camera views. The default of 0 preserves existing default behavior. V 0.8.2 2005-Nov-22 o Add magical file 'dump:' for listing color values numerically to stderr. o Transition from a subdivisible triangle model to a subdivisible space model, using a rudimentary implementation of Hans Moravec's notion of occupancy. o Add support for view and depth output from arbitrary cameras. o Add clipping plane options for 3D modeling. o Fix various bugs in control-point alignment reported by Gregory Maxwell. V 0.8.1 2005-May-6 o Modify --q1 to use median-value incremental rendering. o Add support for median-value incremental and Irani-Peleg rendering. Using a statistic other than the mean was suggested by Scott Scriven as a means of eliminating non-uniform artifacts. Using the median seems to improve performance on Scott Scriven's example sequences, as well as on the scaled output of fine:sinc*lanc for sparse inputs. o Move ale-psf-calibrate to a new scripts directory. o Add support for using control points in 2D and 3D alignment, as well as in 3D model construction. New options include '--gs points', '--cpf-load=', '--cpp-upper=', '--cpp-lower=', '--va-upper=', and '--st'. o Fix enumerator compile bugs noted by Gregory Maxwell and Tom Holroyd to cause compilation failure under GCC 3.4. o Add average magnitude comments to transformation data file output. o Add a color adjustment option --exp-mult=. o For 3D scene reconstruction, use a new unified surface model in place of the depth-based multi-model approach used in 0.8.0. The new model is adjusted on the basis of edge, angle, and color measures. V 0.8.0 2005-Jan-12 o Add a flag --exp-meta-only which causes tonal registration to be performed only on the basis of exposure metadata (e.g., data encoded as EPPM extended attributes). This approach was suggested by Gregory Maxwell. o Set image offsets in d2/render/combine.h. This allows Irani-Peleg rendering to work with --crop when the default rendering chain includes more than one rendering invariant. o Perform Irani-Peleg updating separately by channel instead of using vector operations. This allows divide-by-zero and other conditions to be localized to particular channels. o Modify the Irani-Peleg renderer to use estimate-based certainty. This seems to improve noise characteristics significantly. o Write the results of tonal registration as a comment in the transformation data file. o Add support for PPM with extended attributes (EPPM). Attributes handled specially include black level, shutter speed, aperture, and ISO (or gain). o Add experimental cost calculation routines to d3/scene.h. o Modify euclidean alignment so that perturb-upper and perturb-lower apply to rotational arclength. o Fix an index variable bug in d2::image_bayer_ale_real::trigger(). o Modify d2::exposure one-sided certainty so that the 'one-sided' condition only applies to bright (>50%) areas. Applying it to dark areas has no clear benefit, and an experiment by Gregory Maxwell demonstrates that doing so can exacerbate noise. o Modify d2::align to use unscaled input images when the scale factor is larger than 1.0, or when a scaled_filter interpolant is being used. o Modify d2::image::scale() to allow scale factors in the interval (0, 1), and modify the command-line interface and help text to reflect this change. --scale= now accepts all finite positive values. o Add user interface options --ui=stream and --ui=tty. The latter includes more detailed status output when terminal width information can be obtained (esp. when IOCTL=1 is set at compile time), and is the new default. o Move certain user interface elements to the source subdirectory ui/. o Modify d2::render::ipc::_ip_frame_correct() so that exposure re-estimation uses a ratio of weighted sums instead of a weighted average of ratios. o Modify d2::align::set_exposure_ratio() so that alignment weights and certainty values are taken into consideration. o Add a --cw option to weight alignment error by certainty values, as suggested by Gregory Maxwell. This allows the contributions of pixels at maxval to be diminished, which can increase alignment success in certain cases. o Replace functions d2::incremental::{increase,decrease}_extents() with new functions that take exclusion regions into account. The new functions should also fix a boundary-calculation bug reported by Gregory Maxwell. o Modify d2/render/ipc.h to handle exclusion regions more effectively. o Add --crop argument, which excludes the spatial complement of a specified area over a specified set of frames. Gregory Maxwell notes several advantages of internal over external crops, including preserving knowledge of position in the uncropped frame, which among other benefits allows natural handling of Bayer patterns. o Modify rx_parameters in d2/render.h to use the ale_pos data type instead of int. This should allow exclusion regions to be calculated more accurately. V 0.7.3 2004-Dec-1 o Add incremental 3D reconstruction output. o Remove the reference to a non-existent web page in unsupported::fornow(). o Allow device-specific bayer patterns to be overridden by the --bayer option. o Add an option for explicitly setting the camera view angle. Make the default view angle 43.7 degrees. o Implement optimizations that reduce the memory footprint when 3D options are used. o Modify the 3D cost reduction algorithm. The new algorithm seems to offer better results than the old in cases tested thus far, and does not require that spatial extension be enabled. o Add support for the Canon 300D with a 50mm f/1.4 lens (specifying view angle), as well as experimental support for the 50mm f/1.4 lens at 1.4 (specifying a linear PSF). Also add support for 50mm f/1.8 and 85mm f/1.8 lenses, specifying view angles as specified in the chart at http://www.acapixus.dk/photography/angle_of_view.htm o Don't output final data when --psf-match is specified. Doing so would be useless anyway, and apparently causes a segfault. o For cases where --psf-match is specified, modify the exposure settings for the final input image (i.e., reference image) so that default exposure is used, and modify the bayer pattern settings so that no bayer pattern is used. (The first of these modifications requires changes in the way that the array of input exposures is stored.) o Optionally (when OPTIMIZATIONS == 1) use the output of the default rendering chain directly as the Irani-Peleg initial approximation, instead of copying it. o Add support for PSF convolution and scalar multiplication. o Move all PSF parsing logic to a new file: d2/render/psf/psf_parse.h o Modify help argument processing so that several help arguments can be specified at a time. Change the usage text to reflect this. o Fix concatenated help output; outputs from all help options are now represented. (3D help had been omitted in 0.7.2.) o Add a check to ensure that at most one --q* option is specified. The issue of multiple --q* options being specified was raised on the ALE mailing list by Viktors Rotanovs. As there is currently no support for this, generating an error message is appropriate. V 0.7.2 2004-Oct-26 o Add cost-minimizing code to reconstruct 3D scenes from 2D inputs. (This code is currently very experimental.) o Add rudimentary device support for raw, linear files from the Canon EOS 300D (Digital Rebel) SLR. CRW files may not be directly usable under all configurations; in cases where they are not, Dave Coffin's dcraw program, with arguments -d -4, will produce a raw, linear PPM file. See http://www.cybercom.net/~dcoffin/dcraw/ o Add a new option --gs-mo to establish a minimum overlap area for global searches. This may allow more of Derrick Brashear's historical USGS contour map image sets to align successfully. (from 0.7.1-patch2) o Allow the scale factor to be explicitly set to one. (from 0.7.1-patch2) o Print version information to stdout instead of stderr. (from 0.7.1-patch2) o Add a rudimentary test suite. (from 0.7.1-patch2) o Add support for --perturb-{upper,lower}=x%, where the value x% is specified as a percentage of the smallest image dimension. Use of percentages to specify bounds was suggested by Jeff Epler. (from 0.7.1-patch1) o In render::is_excluded(), add the offset before checking exclusion regions. (from 0.7.1-patch1) o Add code to shrink the accumulated image in d2/render/incremental.h, so that superfluously large undefined areas are never present. This may improve operation of '--gs inner' in some cases. (from 0.7.1-patch1) o In d2::align::_align(), rescale default_initial_alignment in parallel with the current transformation, so that it can be used again, if necessary. (from 0.7.1-patch1) o Add experimental options --perturb-source and --perturb-output, which allow some refinement of the manner in which perturbation occurs. (from 0.7.1-patch1) V 0.7.1 2004-Aug-27 o Fix --visp segfault when not using last: filters. o Add help mode --hA to display all help pages. o Add circular point-spread function option "circle=". o Add support for the ov7620 sensor (raw, linear modes only). (Updated from 0.7.0-patch1 to specify a linear PSF.) o Add global search option --gs to fix an alignment problem reported by Bert Douglas. (Also included in 0.7.0-patch1.) o Change transformation::eu_{get,set,modify}() so that externally visible values are interpreted in the context of transformations between scaled images, while internal values represent transformations between unscaled images. (Bugfix for 0.7.0. Also included in 0.7.0-patch1.) o d2/tfile.h: Ensure that eu[] parameters are properly scaled when read and written. (Bugfix for 0.7.0. Also included in 0.7.0-patch1.) o Fix order-of-operations bug in d2::image::scale_by_half(). (Bugfix for 0.7.0 and earlier versions. Also included in 0.7.0-patch1.) o Scale alignment weights for reduced level-of-detail in d2::align(). (Also included in 0.7.0-patch1.) o For reduced level-of-detail alignment reference images, filter using alignment weights. (Also included in 0.7.0-patch1.) o Add speed optimizations for filtering in the Euclidean case, but leave these disabled, since they are not safe. (Also included in 0.7.0-patch1.) V 0.7.0 2004-Aug-06 o Add support for algorithmic alignment weights. This requires POSIX fork() and execlp(), so add a Makefile variable for POSIX. o Add support for frequency-based alignment weights. Angelo Pesce had initially suggested the related (or more general) idea of edge-based alignment. Frequencies were chosen because of their conceptual simplicity. This option requires that FFTW be linked. o Add support for specifying per-pixel and per-channel alignment weights by providing an additional weight-map image, as suggested by Bert Douglas. o Remove support for USM. o Add multiple default settings: q0, q1, q2, qn, qr. o Partition help into sections, and add a section for transformation data file help. o Add a device type for the XVP610 camera in 640x480 mode. o Modify the divisor in d2/render/ipc.h to ensure convergence when using multiple varieties. o Add experimental handling for Bayer patterns. o Add experimental video stabilization options. o Add options to control output range. By default, use the range of the original frame. o For incremental rendering, add general filtering options. Drizzling options are no longer supported as such, but the help output offers examples of how to emulate old drizzling/merging techniques (roughly). o Add options --fail-default and --fail-optimal to select the desired failure mode. --fail-default uses the default alignment in the case of failure. o Add option --ex, to support exclusion volumes. Region exclusion was first suggested to the author by Dewayne VanHoozer as a means of solving the 'closed eye problem' in group photography. o Add a barrel distortion adjustment multiplier and rate options. o In d2/transformation.h, add parameters for barrel distortion correction. In d2/tfile.h, add new barrel distortion command 'B'. The approach taken is based on that of Helmut Dersch's PanoTools. (i.e., a polynomial in radial distance is used.) o Increment the latest supported transformation file syntax to version 3. This version supports transformation of the original frame, as well as other new features described above. o Move d2/gpt.h to d2/transformation.h. o In d2::align, add support for original frame transformations. o In d2::align::diff() and d2::align::set_exposure_ratio(), treat cases with and without extension identically. o Report unrecognized transformation file commands as errors instead of warnings. o In the transformation data file handler, report incompatible transformation types as an error instead of as a warning. V 0.6.0 2004-Feb-10 o Add a generalized, but rudimentary, implementation of Steve Mann's notion of 'certainty'. For more details, see http://wearcam.org/comparametrics.pdf o Make stdin filter height and width independent of each other. o In the Irani-Peleg renderer, skip frames that fail to reach the match threshold. o Convert some operations on pixels and points into vector syntax through C++ operator overloading. o Add command-line options to select plain or raw PNM/PPM formats. Remove makefile variable PLAIN. o Add command-line options to select 8/16 bits per channel. Remove makefile variable BITS. o Revise the device configuration xvp610_320x240 to use a new filter, reflecting driver updates (see the relevant web page http://auricle.dyndns.org/xvp610/ ) and support for non-linear colorspace point-spread functions. o In the Irani-Peleg renderer, use a discrete Fourier transform to ensure that each (point-spread function, backprojection kernel) pair satisfies condition (9) from theorem 4.1 in the source paper. o Add a point-spread function rasterizer. o Extend the --replace option to support drizzling. o Add support for exposure registration (i.e., matching of exposure between different frames). o Change -Os to -O2 in the Makefile, since -Os no longer achieves speedup in the most critical codepaths. o Add command-line support for summation of point-spread functions. o Add a polymorphic point-spread function type psf and convert all external interfaces of ipc.h and usm.h (formerly hf-enhance.h) to use this type. o Fix memory leak in d2/render/combine.h:get_image(). (This fix is also included in a patch for 0.5.1.) o Modify the USM renderer to write output when incremental output is enabled. o In the USM renderer, now only defined pixel values contribute to the mask. Also, undefined values are no longer masked. o Update e-mail address information. o Modify the Irani-Peleg calibration script into a general point-spread function calibration script, using a new built-in point-spread function evaluation module to rate candidates. o Irani-Peleg and USM (High-frequency enhancement) renderers now use the same point-spread function configurations. New options --ips, --usm, --lpsf, --nlpsf, and --device subsume and extend the functionality provided by options --ip, --ipc, and --hf-enhance. o Add support for convolutions in non-linear colorspace. This feature is enabled and configured by the command-line option --nlpsf. (See also the item above.) o Linearize channel values within internal data structures so that most ALE operations are performed on linear data. Steve Mann discusses the use of linear representations in image processing, e.g. in his paper http://wearcam.org/comparametrics.pdf . We assume a simple power-law response by default. o Modify the image class to use a floating-point data type for storing pixels. o Modify the README to remove information covered in the User Manual. o Revise identifiers and comments in d2/render/ipc.h to better reflect the terminology used in the source paper by Irani and Peleg. o Consoldiate code for computing the position and dimensions of a pixel in a new coordinate system, and use this new abstraction to reduce the code size of d2/render/ipc.h and d2/render/drizzle.h (Irani-Peleg and drizzling code, respectively). o Change several instances of 'double', 'float', and 'my_real' to specialized floating-point types 'ale_real', 'ale_pos', 'ale_sreal', and 'ale_accum'. o Fix offset calculation in d2/render/ipc.h. This is necessary for Irani-Peleg rendering of image mosaics extending upwards or to the left of the original frame. (This fix is also included in a patch for 0.5.1.) o Move classes treating snapshots as two-dimensional data to directory 'd2' and create an associated C++ namespace. We can't use '2d' to label the namespace, because the C++ grammar won't allow it. V 0.5.1 2003-Nov-19 o Several of the changes below are based on a suggestion by Bert Douglas regarding support for 16-bit-per-channel color. See the README for more information about relevant compilation options. o Add information to the README regarding new compilation options. o Modify the makefile to accept a variable BITS, and differentiate between values BITS=8 and BITS=16. The latter option causes the macro BITS_16 to be defined during compilation. o Modify image_rw.h to handle 16-bit data when BITS_16 is defined. Also, differentiate between 8-bit and 16-bit ImageMagick builds by checking MaxRGB. o In ppm.h, add carriage returns to the set of recognized whitespace characters. o Modify ppm.h to read 16-bit binary PPM files (added to the PPM format spec in April 2000). o Modify ppm.h to read plain (ASCII) as well as raw (binary) PPM files. o Add a Makefile option for writing plain (ASCII) PPM files instead of raw (binary). This option causes the macro PPM_PLAIN to be defined during compilation. o Modify ppm.h to write plain (ASCII) PPM files when PPM_PLAIN is defined. o Modify ppm.h to output 16-bit PPM files when BITS_16 is defined. o Modify ppm.h to scale input intensity values based on the internal representation depth (8 or 16 bits per channel). o Add a file 'channel.h' to describe the color channel data type and valid range, both being dependent on whether BITS_16 is defined. Use these generic values, where appropriate, throughout the ALE codebase. V 0.5.0 2003-Nov-02 o Remove certain cloning operations from align.h, but since cursory tests indicate that scaling with --scale is much more expensive than cloning, allow cloning to occur when scaling occurs. o Add more comment documentation to header files. o Emit a more informative error message when the PPM file handler encounters a file that is not a well-formed PPM binary file. o Move rendering implementations to subdirectory 'render/'. o Modify semantics of alignment following by applying to file-loaded initial transformations a delta transformation D = AB^-1, where B is the previous frame's (unmodified) initial transformation, A is the previous frame's final transformation, and ^-1 is the inverse operator. Using --follow with --trans-load can now improve alignment success when working with panoramic image mosaics. o We're not using simulated annealing, so remove comments that claim otherwise. o Remove certain unsafe assumptions from ipc/* (now render/ipc/*); this change includes a modification to ipc.h (now render/ipc.h). Limits of the rectangle used as an argument to the ::response() function are now explicitly given rather than implied. o Change documentation for --replace. V 0.4.8 2003-Aug-01 o Modify Irani-Peleg renderer to produce incremental output. o Modify Monte Carlo alignment so that the same set of accumulated image pixels is examined when comparing two transformations. o Add an option for additional upper-bound constraint of rotational perturbation. Jeff Epler had noted that the perturb-upper/perturb-lower options alone may not be suited to working with sets of higher-resolution images. o Resolve a bug introduced in version 0.1.1 which had limited rotational perturbation to 2 degrees. o Add an option to adjust the maximum level of detail used. The default maximum is 2/perturb, which matches the default for previous versions of ALE. o Modify names of temporary files used in the calibration script. V 0.4.7 2003-Jul-27 o Add a replacement option suggested by Jeff Treece. This option can be used to facilitate video stabilization. o Irani-Peleg: add support for configurable modules, including a module that reads its configuration data from standard input and a module calibrated for an IBM (Xirlink) XVP610 in 320x240 mode. A rudimentary script for calibrating devices with unknown projection functions has been included as ipc/ale-calibrate. o Irani-Peleg: don't truncate correction values in backprojection. o Irani-Peleg: don't multiply the weight function by a scale correction factor in backprojection. o Rename render::operator()() to render::sync(). Update subclasses accordingly. V 0.4.6 2003-Jul-01 o Allow --ip and --hf-enhance to be used together. [Modify ip::operator() and hf_filter::operator() so that multiple post-processing filters can be used.] o Initialize the drizzled image to be uniformly black. This fixes a bug introduced in 0.4.2. o Allocate the correct size image for drizzling. This fixes a bug introduced in 0.4.5. V 0.4.5 2003-Jun-23 o Ensure correct transformation scaling and difference calculation after alignment is complete, even if alignment terminates with a reduced level of detail (i.e. perturb-lower > 2). o Separate the scale() function into two cases: scale() is reserved for scale factors greater than or equal to one, as in user-specified scaling; and scale_by_half() is used for the scale factor 0.5, needed to provide multiple levels of detail in alignment. Modify the scale_by_half() case to reflect source pixel values more fairly. (This change affects alignment behavior at reduced levels of detail.) o Reduce whitespace in usage() message. o Modify align::diff() to use correctly scaled image offset values. (Bugfix for alignment with --extend.) o Modify align.h so that the image definition array is correctly scaled for all levels of detail. (Bugfix for alignment with --extend.) o Modify image.h to correctly handle image offset values. (Bugfix for --extend operation.) o Remove call to stat() in image_rw.h. This improves OS independence, and apparently also allows URL-specification of images when compiled with ImageMagick support. o Modify image file handler interface so that input files are not scaled. Perform scaling, when necessary, outside of the file handler. Since unscaled data is needed by the drizzling and Irani-Peleg code, this fixes bugs in those modules. V 0.4.4 2003-Jun-06 o Modify the Monte Carlo pixel selection algorithm so that the expected number of sampled pixels more closely matches the specified number in typical cases. o Specify the binary mode flag to fopen() calls in the PPM file handler. This change resolves a bug discovered by Benjamin Hill. V 0.4.3 2003-May-30 o Add support for Monte Carlo alignment of images, in which only a random subset of pixels is sampled. o Add an option to disable incremental image output. V 0.4.2 2003-May-23 o Implement an image reconstruction option based on the work of Irani and Peleg. o Clean up source; move rendering and alignment functions into separate files. o Change valid drizzling diameter interval to (0,1]. o Modify PPM file reader to correctly handle comments in PPM files; this resolves a bug pointed out by Benjamin Hill. o Add missing typecast to resolve compile warning under GCC 3.2. o Make changes to gpt.h that may reduce the Euclidean alignment time. o Move ale.c to ale.cc to follow one of the many C++ naming conventions. V 0.4.1 2003-Apr-28 o Change language to C++. o Code cleanup in ale.c, image.h, and gpt.h. o Separate into a number of subsections the option descriptions in the README o Add URL information to README o Add an experimental drizzling implementation. Research on drizzling by Richard Hook and Andrew Fruchter was brought to the attention of the author by Dan Kaminsky. o Add an option to use the previous frame's final transformation as the default alignment. o Change pixel weight data type so that more than 255 images can be merged. o Add support for increased spatial extents. Research on increased spatial extents by Steve Mann was brought to the attention of the author by Dan Egnor. o Modify the transformation algorithm to use transformations from the domain of the input image to the range of the target image. This change is reflected in transformation files. Maintain support for old transformation file versions, however. o Add version information to transformation files and update the version from 0 to 2. V 0.4.0p1 2003-Apr-04 o Merge a bugfix from Debian ALE package version 0.4.0-1. Without this fix, an assertion failure can occur when ImageMagick support is enabled. Original fix implemented by Nick Rusnov. V 0.4.0 2003-Mar-30 o Add support for general scaling parameters (i.e. all scale factors >= 1.0). --scale2, --scale4, and --scale8 are now deprecated, and replaced with a more general --scale=x argument. o Support enhancement of high frequencies even when the scale factor is 1.0. o Modify the high-frequency filter algorithm to support filtering near the border of an image. o Modify the high-frequency filter function so that the response is now (4/n)^2 times what it used to be, where n is the scale factor. V 0.3.2 2003-Mar-26 o Don't filter high frequencies if we're not enhancing them. This improves efficiency, but should not affect output. V 0.3.1 2003-Mar-25 o Output average match statistic. o Update informational output to transformation files to include original frame. o Add support for post-enhancement of high-frequency details. V 0.3.0 2003-Jan-17 o Add support for loading and saving transformation data. o Add an option to set the upper bound on correction steps. o Modify Makefile to compile with size optimization, since this appears to improve speed characteristics in some cases. /alignment o Move transformation data structure and related functions to a separate header file. V 0.2.0 2003-Jan-01 o Add support for general projective transformations, and change/add options as follows: '--translation' used to be '--no-rotate' '--euclidean' used to be '--rotate' '--projective' is a new option V 0.1.2 2002-Dec-13 o Add optional support for .jpg, .png, .tiff, and other file formats through ImageMagick. Translation using ImageMagick was suggested by Nick Rusnov. /image-files o Don't segfault if a file can't be opened. V 0.1.1 2002-Dec-09 o Use reduced levels of detail in coarser alignment steps to increase speed. o Change perturbation step lower-bound check from less-than ('<') to less-than-or-equal-to ('<='). Change default lower bound to .125 from .1 (the behavior is the same, but the value makes more sense). o Change perturbation initial value to 32 pixels from 16 pixels, since coarse alignment is now less expensive. o Modify scale function so that the borders aren't corrupted (too badly). V 0.1.0 2002-Nov-26 o Add support for correction of rotation about the lens axis. o Add an optional match criterion for merging. o Add an option to adjust minimum step-size. o Add flags to specify which channels to use for alignment. Use a summation of all channels by default. o Add an option to modify the error metric exponent, and change the default value from 1 to 2. o Display information about how well a new image matches the accumulated image. o Add a rule for ale.exe to the Makefile. V 0.0.0 2002-Oct-11 /initial-release o Initial release. ale-0.9.0.3/doc/package/todo/0000755000175000017500000000000011164421452015753 5ustar dhilvertdhilvertale-0.9.0.3/doc/package/todo/index.xml0000644000175000017500000002070511164421407017610 0ustar dhilvertdhilvert
To-do list This article contains a tentative list of future versions and features.
0.9.0 Argument scope
  • Fix bugs in argument scope handling.
 Multiple-pass registration
  • Revise alignment algorithm to allow multiple passes for less sensitivity to noise and better estimation of tonal certainty.
 3D scenes and depth recovery
  • Revise 3D scene reconstruction algorithm to perform acceptably on a wider variety of scenes.
 PSF windowing and infinite-support PSFs for Irani-Peleg rendering
  • Add syntax for PSF windowing and new PSF types with infinite support, including the gaussian kernel, suggested by HJ Hornbeck.
Variable lighting
  • Add a facility for handling variation in lighting between input frames.
 Interchange formats
  • Add support for a commonly-used interchange format, such as autopano pto, suggested by Peter Miller.
 Raw file handling
  • Use Dave Coffin's dcraw program to extract information from raw files, including pixel data, as well as black level and other meta-data, as suggested by Gregory Maxwell.
Abstract and partial transformations
  • Add a generic 2D transformation class, supporting partial transformations.
    • 'partial transformation', as used here, means that it is expected that some points will fail to map.
  • Add a partial 2D transformation class with constructor taking as arguments a pair of 3D projective transformations and a 3D model.
File scoping
  • Add new file-scoped options
    • Irani-Peleg
    • black level
    • alignment type
    • focus details
Irani-Peleg for 3D models
  • Modify existing Irani-Peleg code to use generic (partial) 2D transformations.
    • in combination with the above, this should allow the algorithm to operate on 3D models.
Focus bracketing for depth-of-field expansion
  • Add facilities for handling depth-of-field and focus bracketing in input image sets, as suggested by Viktors Rotanovs and Gregory Maxwell. This change will likely involve:
    • using the 3D model for depth data, as suggested by Gregory Maxwell
    • using user-provided (file-scoped) focus details to determine depth of field
    • using variable PSF in the Irani-Peleg algorithm, as suggested by Gregory Maxwell
    • developing an approach to handle the incremental (non-Irani-Peleg) case.
Output image characteristics
  • Allow specification of output image characteristics, including exposure (e.g., gamma) and channel offsets within a pixel.
Output devices
  • Add support for specifying output devices, such as LCD monitors, to allow shorthand customization of exposure (e.g., gamma) and other characteristics, such as channel offset in the case of LCD screens for sub-pixel anti-aliasing.
Weight and certainty upper bounds
  • Add support for specifying weight and certainty upper bounds for rendering, either as an absolute constraint or relative to average weights, so that the overall contributions to an output pixel (or channel) are constrained by weight.
Time locality
  • In combination with weight and certainty upper bounds, time locality could be used to determine which frames are used to generate an output pixel. As a special case of this, video stream processing could favor frames having the smallest time difference from the target frame.
1.0.0 (Stable)
Performance
  • Refine rendering and alignment code for better performance.
Synchronized frame set syntax
  • Add syntax to identify synchronized frame sets.
Internationalization
  • Enhance the command-line interface in preparation for i18n. (?)
    • e.g., syntax for identifying synchronized frame sets
  • Internationalize the command-line interface and help text to accommodate translations.
Technical Manual Updates
  • Update the Technical Manual for information regarding 3D operation.
Unsorted
Documentation
  • Generate correctly indented book-level tables of contents when rendering the complete set of manuals.
  • Add a tutorial, and credit Metin Toyran for suggesting a step-by-step guide.
  • Remedy meaningless page numbers for book title pages in the set ToC.
  • Complete migration of existing documentation from the localhost sub-directory, removing superfluous license terms in the footers.
  • Centralize licensing and authorship information (e.g., there should be only one COPYING file and only one AUTHORS file).
  • Include license and copyright terms for the doc tree Makefile as copyright notices in the AUTHORS and/or COPYING files (or equivalent).
  • Complete the documentation.
  • Revise the user manual for new features and syntax.
    • Document new scoping operators {}, [], and [<>].
    • Document other changes in UI, including regularization of syntax.
      • in particular, commas can no longer appear in single-argument options when using assignment-delimited syntax; use space-delimited syntax instead. This behavior is inconsistent with 0.8.4.
Integer-value routines
  • Add facilities for manipulating images storing color as integer-valued data, possibly as library routines.
Library
  • Move image-processing routines into a library that can be used by other programs.
Language Bindings
  • Add bindings for other programming languages.
Packaging
Complete Package
  • Investigate options for distributing a 'complete' package including full revision history, pre-built documentation (if the ordinary distribution does not include this), and, possibly, example image sets. Direct download, bittorrent and CD are the most prominent candidates for distribution.
    • In the case of CD distribution, information should probably be added to the manuals regarding how to update CD-provided program source.
Windows Package
  • Investigate options for creating and distributing a combined source and binary Windows package containing sufficient software to ensure support for common image types (e.g., by statically linking with libraries for opening JPEG and PNG files). BitTorrent and CD are the most obvious candidates for distribution.
    • This package could build on the package described above, as a 'for Windows' variant or some such.
    • This package could make use of an application such as InstallJammer or Nullsoft Scriptable Install System for installation.
ale-0.9.0.3/doc/technical/0000755000175000017500000000000011164421407015345 5ustar dhilvertdhilvertale-0.9.0.3/doc/technical/index.xml0000644000175000017500000001373311164421407017205 0ustar dhilvertdhilvert Technical Manual
Purpose (foobar) This page summarizes program operation and command-line usage for ALE versions 0.8.0 through 0.8.4. Features specific to a particular version are annotated (e.g. [ALE 0.8.1 and later]). Manual pages linked from this section describe default settings, file output, alignment, rendering, exclusion regions, control points, user interfaces, devices, and 3D scene reconstruction. For more information on ALE, see the ALE Home Page.
Parameter Meta-syntax
<foo> A required parameter called foo.
[<foo>] An optional parameter called foo.
[<foo>]* Zero or more parameters foo.
Command-line syntax for Image Processing The following command-line invocation can be used to process a series of frames into an output file: 
ale [<option>]* <original-frame> [<supplemental-frame>]* <output-file>

Option Arguments

Certain basic modes of operation, emphasizing image quality, speed, or other rendering characteristics, are now established in the form of default settings. Other options are outlined in the manual pages describing file output, rendering, alignment, exclusion regions, devices, user interfaces, and 3D scene reconstruction.

Image Files

ALE can be configured at compile time to use one of two different file handlers. Execute 'ale --version' to determine which file handler is being used. The table below outlines the supported formats for each file handler.
Version MessageFile Types Supported
File handler:     ImageMagick
 Input and output files can be any of the formats supported by ImageMagick. 
File handler:     PPM
 Input files must be PPM, and output files are written as PPM.
Note that many external programs, including ImageMagick's command line utilities, can be used to convert between PPM and other formats. See the README included in the source distribution of ALE for more information about compile-time configuration of file handlers.
Command-line syntax for Version Information The following command-line invocation can be used to print version information and build options: 
ale --version
The following is sample output from this invocation: 
ALE Version:      0.8.4
File handler:     ImageMagick
Color data:       SINGLE
Coordinate data:  SINGLE
DFT:              FFTW3
Assertions:       Enabled
Optimizations:    Enabled
The first line of output indicates the version of ALE source code being used; the remaining lines reflect the build options selected at compile time. For more information about build options, see the README file included in the ALE source distribution.
Command-line syntax for Help Output When invoked with no arguments, or an insufficient number of file arguments, ALE outputs a help message specifying command-line usage and available help topics. The following is a sample invocation: 
ale

Help Topics

Summary

Between versions 0.5.1 and 0.7.0, alignment times show a steady improvement, but this can be partly explained by a change in the default alignment settings in 0.7.0. Rendering times, on the other hand, are about 6 times longer for 0.7.0 than for 0.5.1, as a consequence of renderer changes. More detailed summaries for alignment and rendering tests follow.

Alignment

Alignment times improve as the version number increases, through version 0.7.0, but note that version 0.7.0 with the --q0 option defaults to --mc 30, which offers less accurate alignment than is offered by other versions' configurations. (Instead of sampling the difference between images for each reference image pixel, --mc 30 specifies that differences be sampled at roughly 30% of reference image pixels.)

Rendering

Rendering times increase significantly with version number, through version 0.7.0, the most significant increase being between 0.6.0 and 0.7.0, as the latter uses a computationally more expensive rendering technique. Whether the improved rendering quality is worth the extra rendering time likely depends on subjective criteria, but the differences seem to be most apparent when performing relatively complex rendering tasks.

Option Arguments

Options are outlined in the manual pages describing file output, rendering and alignment.

Image Files

ALE can be configured at compile time to use one of two different file handlers. Execute 'ale --version' to determine which file handler is being used. The table below outlines the supported formats for each file handler.

Version MessageFile Types Supported 
File handler:     ImageMagick

Input and output files can be any of the formats supported by ImageMagick. 

File handler:     PPM

Input files must be PPM, and output files are written as PPM.

Note that many external programs, including ImageMagick's command line utilities, can be used to convert between PPM and other formats.

See the README included in the source distribution for more information about compile-time configuration of file handlers.

Command-line syntax for Version Information

The following command-line invocation can be used to print version information and build options: 

ale --version

ALE Rendering

Rendering determines how an output image is constructed from a series of aligned input frames. The incremental renderers, merging and drizzling, update the output image after reading each new frame from the series, whereas non-incremental renderers wait until the last frame has been loaded before producing output. More than one renderer can be involved in producing the final output. Available rendering options are outlined below.

Merging

Merging, the default incremental renderer, works most effectively on images that have no large changes in scale (e.g. camera zooming). Since it uses bilinear interpolation, output images are approximately convolved with the triangle, or Bartlett, filter, and may appear to have reduced contrast and resolution when compared with the output of other renderers.

Drizzling

The drizzling renderer is an incremental renderer that can usually produce better images than merging, but it works most effectively with devices having very little blur and optical distortion. Devices sampling very small angles of the scene at each pixel are ideal; hence, if very fine staircase aliasing is visible in the input frames, drizzling should work very well. (For creation of higher resolution images with drizzling, use also the --scale option described below.) 
--drizzle-diam=x  Drizzle with input pixel diameter x (where x > 0)
--drizzle-only    If drizzling, output black for pixels with no drizzle data.

For more information about drizzling, see the paper by Richard Hook and Andrew Fruchter, "Variable-Pixel Linear Combination", or the following URL:

http://www.cv.nrao.edu/adass/adassVI/hookr.html

Point-spread Function (PSF)

Non-incremental renderers use a point-spread function to model the optical and electronic properties of the capture device used. The PSF can be specified in terms of a linear and non-linear component. The non-linear component is disabled by default.

Determining the PSF

The point-spread function can be approximated through trial-and-error or based on known scenes. ALE includes a script that numerically approximates the point-spread function based on images captured from known scenes. This script can be found in the source distribution (d2/render/psf/ale-psf-calibrate).

Device Specification

If a device is known to ALE, then its PSF can be implicitly set with the device option. 
--device <d>      Set the capture device to <d>.
Available devices are as follows: 
xvp610_320x240    IBM PC Camera Pro (XVP610) in 320x240 mode.

PSF specification

The PSF can also be explicitly specified by using one or both of the psf options. These options have precedence over the device option. 

--lpsf <p>        Set linear colorspace point-spread function to <p>
--nlpsf <p>       Set non-linear colorspace point-spread function to <p>
Available explicit point-spread functions are as follows: 
box=<d>           Set the PSF to a box filter with diameter <d>.
stdin             Specify a custom filter at runtime.
<p>+<p>           Summation of two functions

Unsharp Mask (USM) Renderer

This non-incremental renderer uses an unsharp mask to compensate for blur introduced by the image capture device. It is fairly inexpensive computationally, but it may not be effective in all cases. 

--usm <m>         Apply an unsharp mask with multiplier <m>.

Irani-Peleg iterative solver

This non-incremental renderer is very general, and attempts to reconstruct the original scene based on the captured frames and the PSF. Unlike the USM renderer, it can compensate for blur introduced by the incremental renderers, and it may be more effective than the USM renderer in compensating for blur introduced by the image capture device.

Note that this method can take a long time to produce output. If incremental output is enabled (see below), output is written after each iteration is complete. Using more iterations will generally improve output, up to the point of convergence, when additional iterations have no effect. A dot is displayed to indicate the completion of each iteration. 

--ips <i>         Run <i> iterations.

For more information on the iterative backprojection technique of Michal Irani and Shmuel Peleg, see their paper, "Improving Resolution by Image Registration", at

ftp://ftp.wisdom.weizmann.ac.il/pub/irani/PAPERS/SR_CVGIP91.pdf

Exposure Registration

By default, ALE adjusts an exposure model to minimize differences in tone between frames. The option --exp-noregister indicates that exposure should be assumed uniform across all frames. In this case, no adjustment is performed.

--exp-register    Register exposure between frames.  [default]
--exp-noregister  Assume uniform exposure across all frames.
For more information about analyzing and processing images having differing exposures, see Steve Mann's comparametric paper, at

http://wearcam.org/comparam.htm

Certainty-weighted Rendering

The exposure model in ALE includes an associated certainty function, which quantifies the reliability of sensor measurements. By default, this function is raised to the zeroth power to obtain uniform certainty for all measurements. To specify a different certainty exponent, the option --cx can be used. 

--cx <x>          Render with certainty exponent <x>
--no-cx           Render with uniform certainty.  [default]
Note that ALE uses a one-sided certainty function, biased by backprojection value, in Irani-Peleg rendering. In some cases, this approach seems to offer better results than the unbiased function used in drizzling and merging. For more information on the certainty weighting approach used by ALE, see the ALE source code.

For more information on Steve Mann's original approach to certainty-weighted rendering, see his comparametric paper, at

http://wearcam.org/comparam.htm

Scale factor

Rendering with a larger scale factor causes internal data structures to store more information, resulting in image output of the specified larger scale. Larger scales can improve alignment precision and output image quality, but can also increase alignment and rendering times. 
--scale=x         Scale images by the factor x (where x is at least 1.0)

Image extents

The --extend option records pixel data that falls outside of the region of the first frame in the sequence. This can be useful for providing additional alignment constraints or creating panoramic image mosaics. (See also the description of the --follow option in the alignment section.) 
--extend          Increase image extents to accommodate all pixel data.
--no-extend       Don't increase extents; crop to original frame. [default]

Incremental output

By default, the output file is written every time a renderer completes an update cycle. In order to suppress output until the final image is rendered, specify the --no-inc option. 
--inc             Produce incremental output.  [default]
--no-inc          Don't produce incremental output.

Pixel replacement

When using the merging or drizzling renderer, --replace indicates that each new frame should replace the corresponding region of the rendering, instead of being averaged with data from previous frames. This option was originally suggested by Jeff Treece for use in stabilization of video streams. His approach to stabilization is outlined below.

Video Stabilization

If the files 

0.ppm, 1.ppm, ..., 9.ppm
represent frames from an unstabilized video stream, then the following sequence of commands may result in a stabilized sequence: 
ale --replace         0.ppm 1.ppm 1.stable.ppm
ale --replace  1.stable.ppm 2.ppm 2.stable.ppm
ale --replace  2.stable.ppm 3.ppm 3.stable.ppm
.
.
.
ale --replace  8.stable.ppm 9.ppm 9.stable.ppm

The resulting stabilized sequence would be: 

0.ppm, 1.stable.ppm, 2.stable.ppm, ..., 9.stable.ppm

Option Syntax

--replace         Replace overlapping areas when merging and drizzling.
--no-replace      Do not replace.  [default]

Alignment

Alignment compares each supplemental frame in the sequence with an intermediate rendering known as the reference image. Based on this comparison, a transformation is assigned to the supplemental frame. Many different transformations can be assigned before alignment of the frame is complete.

Match statistics

The match statistic is a single number indicating how well two frames are aligned; this number is used to select or reject transformations during alignment. After alignment is complete, ALE displays the final match statistic. If the value is close to 100%, then the frames are well aligned. Very low values can indicate misalignment. However, even frames that are very well aligned do not usually achieve 100% alignment, and, for improving image quality, ALE works most effectively when match values are less than 100%.

Match threshold

A match threshold can be specified; no images with final match statistics falling below this threshold will contribute to the final output. 
--threshold=x     Min. match threshold; a perfect match is 100.  (0 is default)

Alignment error metric exponent

The function calculated at each pixel to determine the match statistic is known as the alignment error metric, and is of the form (a-b)x. The value x is known as the error metric exponent, and is 2 by default. Larger numbers usually mean that alignment will be more influenced by smaller image features. 
--metric=x        Set the alignment error metric exponent.       (2 is default)

Alignment Channel Options

In calculating the per-pixel error metric, there are three ways in which ALE can handle color channels. By default, ALE adds the channels before calculating the match. However, ALE can also rely solely on the green color channel or use all three channels separately. 
--align-all       Align images using all color channels
--align-green     Align images using the green channel
--align-sum       Align images using a sum of channels [default]

Monte Carlo Alignment

Aligning large images can take a very long time if all pixels are examined in determining the match statistic, so it is often desirable to examine a smaller number of pixels. The Monte Carlo alignment option allows this. The number of pixels used is specified as a percentage, and smaller numbers usually mean faster, but less precise, alignment. 
--mc <x>          Align using, on average, x% of available pixels (0 < x < 100)
--no-mc           Align using all pixels.  [default]

Perturbation

Every dot displayed after an input filename indicates a change in perturbation size. The size is initially set to be high, allowing large changes in alignment to be evaluated, and is reduced as the locally optimal alignment is found for each size. When this size drops below a specified lower bound, the frame is considered to be aligned.

Perturbation bounds

These options determine the upper and lower bounds for perturbation size. The perturb-upper and perturb-lower bounds apply to rotation (in degrees), translation (in pixels), and the movement of the boundaries of a projected frame (in pixels). The rot-upper bound disables rotational perturbation above a certain perturbation size (in degrees). To disable alignment, set perturb-upper to zero. 
--perturb-upper=x Perturbation upper bound in pixels/degrees  (32.0 is default)
--perturb-lower=x Perturbation lower bound in pixels/degrees  (.125 is default)
--rot-upper=x     Rotation-specific perturbation upper bound  (32.0 is default)

Level of detail

Alignment at large perturbation sizes is usually carried out on reduced-detail images. To disable this, set lod-max to log2(perturb-upper). 

--lod-max=x       LOD scale factor is max(1, (2^floor(x))/perturb)  (1 is def.)

Transformations

The variables used to adjust alignment are called transformations, and map points from a source image to a target image.

There are three transformation classes that can be used by ALE. The translational class applies only translations to the inputs, changing only the position of images; the Euclidean class applies translations and rotations; and the projective class applies general projective transformations, which are the most general type of transformation supported by ALE.

The Euclidean class is most appropriate for use with scanners and as a first pass for projective transformations. The projective class is most appropriate for use with cameras.

Except when capturing flat scenes, ALE does not correct for perspective changes, so movement of cameras should ideally be constrained so that no large translations occur.

Transformation Class Options

--translation     Only adjust the position of images
--euclidean       Adjust the position and orientation of images [default]
--projective      Use projective transformations.  Best quality, but slow.

Transformation data file options

Transformations used in alignment can be loaded from a file or saved to a file. This can be useful when performing alignment in several passes, or when refining rendering options.

Note that projective transformation data saved to a file cannot be used to initialize other transformation types. 

--trans-load=x    Load initial transformation settings from file x
--trans-save=x    Save final transformation data in file x

Alignment following

When frames are more closely aligned with adjacent frames in the sequence than they are with the first frame in the sequence, alignment success can be improved by specifying the --follow option. This option can be effective even when initial alignment information is loaded from a file. 
--identity        Frames align closely with the original frame.  [default]
--follow          Frames align closely with their immediate predecessor.

ALE File Output

File output options determine the format in which rendered images are written. Depending on the compilation options used, available file output options vary.

PPM Output

All builds of ALE support PPM output. PPM can be written in plain (ASCII) or raw (binary) format. If ALE has been built without ImageMagick support, or if the file type cannot be automatically determined by file extension, then raw PPM output is used by default. 
--raw             Write raw PPM output
--plain           Write plain PPM output

Extension-based file type determination

If ALE has been built with ImageMagick support, then the output file type can be determined automatically by file extension. This is the default behavior for ImageMagick builds. The --auto flag explicitly specifies that the default behavior should be used. This flag generates an error on builds compiled without ImageMagick support. 
--auto            Determine file type automatically

Output Color Depth

Output color depth of 8 or 16 bits of precision per color channel can be specified, for 24-bit or 48-bit color, respectively. 
--8bpc            Write 8 bit per channel output [default]
--16bpc           Write 16 bit per channel output

ALE 0.5.1 User Manual

Purpose

This page summarizes ALE program operation and command-line usage.

Other manual pages in this section describe rendering and alignment.

For more information on ALE, see the ALE Home Page.

Program Operation and Usage

Parameter Meta-syntax

 <foo> A required parameter called foo.
[<foo>] An optional parameter called foo.
[<foo>]* Zero or more parameters foo.

Command-line syntax for Version Information

The following command-line invocation can be used to print version information and build options: 

ale --version
The following is sample output from this invocation: 
ALE Version:      0.5.1
File handler:     ImageMagick
Bits per channel: 8
The above output indicates that the ALE version is 0.5.1, that ImageMagick is being used to handle image files, and that a 24-bit color space is being used.

Command-line syntax for Help Output

When invoked with no options, or options detected as incorrect, ALE outputs a help message specifying command-line usage and available options. The following is a sample invocation: 
ale

Command-line syntax for Image Processing

The following is the normal command-line invocation for ALE, and is used to process a series of frames into an output file: 

ale [<option>]* <original-frame> [<supplemental-frame>]* <output-file>

The original-frame parameter, and each supplemental-frame parameter, should match the filename of an image file. Output will be written to the output file specified.

Depending on compile options, the file handler used may be ImageMagick or an internal PPM file handler (use the --version flag to check this). When ImageMagick is used for file handling, input files can be any of the types that ImageMagick can handle, and the output file type should be specified by file extension. The internal PPM file handler can be used to read and write PPM files only. However, on many platforms, ImageMagick's command line utilties can be used to convert between PPM and other file formats.

Options are outlined in the rendering and alignment subsections.

ALE Rendering

Rendering determines how an output image is constructed from a series of aligned input frames. The incremental renderers, merging and drizzling, update the output image after reading each new frame from the series, whereas the non-incremental renderers wait until the last frame has been loaded to produce output. More than one renderer can be involved in producing the final output image. Available rendering options are outlined below.

Merging

Merging, the default incremental renderer, works most effectively on images that have no large changes in scale (e.g. camera zooming). Since it uses bilinear interpolation, output images are approximately convolved with the triangle, or Bartlett, filter, and may appear to have reduced contrast and resolution in comparison with other renderers.

Drizzling

The drizzling renderer is an incremental renderer that can usually produce better images than merging, but it works most effectively with devices having very little blur and optical distortion. Devices sampling very small angles of the scene at each pixel are ideal; hence, if very fine staircase aliasing is visible in the input frames, drizzling should work very well. (For creation of higher resolution images with drizzling, use also the --scale option described below.) 
--drizzle-diam=x  Drizzle with input pixel diameter x (where 0 < x <= 1).
--drizzle-only    If drizzling, output black for pixels with no drizzle data.

For more information about drizzling, see the paper by Richard Hook and Andrew Fruchter, "Variable-Pixel Linear Combination", or the following URL:

http://www.cv.nrao.edu/adass/adassVI/hookr.html

High-frequency enhancement

This renderer uses an unsharp mask to enhance the contrast of high frequencies. It can be used to compensate for systematic blurriness introduced by merging, drizzling, or the image capture device. However, better results will generally be achievable by using a separate postprocessing tool, such as the GIMP or CinePaint (formerly called Film GIMP). In addition to the built-in unsharp mask, the GIMP can make use of Ernest Lippe's refocus plugin. 

--hf-enhance=x    Enhance high frequency details by factor x.  (0.0 is default)

Irani-Peleg iterative image reconstruction

This renderer is by far the most general, and can be used to compensate for blurring introduced by the image capture device. In order to use it most effectively, an approximation of the projection function for the capture device should be known. Two general classes of projection functions are supported: box filters and custom filters.

If rendering with the box filter option, manual experimentation can be used to find a diameter that works well. Alternatively, ALE includes a script that calibrates custom filters for devices, based on images captured from known scenes.

Two custom filter options are included: one for the IBM PC Camera Pro (XVP610) in 320x240 mode, and one for interactive filter specification.

Note that this option can take a long time to produce output, especially on large images. If incremental output is enabled (see below), output is written after each iteration is complete. Using more iterations will generally improve output, up to the point of convergence, when additional iterations have no effect. A dot is displayed to indicate the completion of each iteration. 

--ip <d> <i>      Solve for a box filter with diameter <d> over <i> iterations.
--ipc <c> <i>     Solve for device config <c> over <i> iterations.
The available device configurations are as follows: 
xvp610_320x240
stdin

ftp://ftp.wisdom.weizmann.ac.il/pub/irani/PAPERS/SR_CVGIP91.pdf

Scale factor

Rendering with a larger scale factor causes internal data structures to store more information, resulting in image output of the specified larger scale. Larger scales can improve alignment precision and output image quality, but can also increase alignment and rendering times. 
--scale=x         Scale images by the factor x (where x is at least 1.0)

Image extents

The --extend option records pixel data that falls outside of the region of the first frame in the sequence. This can be useful for providing additional alignment constraints or creating panoramic image mosaics. (See also the description of the --follow option in the alignment section.) 
--extend          Increase image extents to accommodate all pixel data.
--no-extend       Don't increase extents; crop to original frame. [default]

Incremental output

By default, the output file is written every time a renderer completes an update cycle. In order to suppress output until the final image is rendered, specify the --no-inc option. 
--inc             Produce incremental output.  [default]
--no-inc          Don't produce incremental output.

Pixel replacement

When using the merging renderer, --replace indicates that each new frame should replace the corresponding region of the rendering, instead of being merged with data from previous frames. This option was originally suggested by Jeff Treece for use in stabilization of video streams. His approach to stabilization is outlined below.

Video Stabilization

If the files 

0.ppm, 1.ppm, ..., 9.ppm
represent frames from an unstabilized video stream, then the following sequence of commands may result in a stabilized sequence: 
ale --replace         0.ppm 1.ppm 1.stable.ppm
ale --replace  1.stable.ppm 2.ppm 2.stable.ppm
ale --replace  2.stable.ppm 3.ppm 3.stable.ppm
.
.
.
ale --replace  8.stable.ppm 9.ppm 9.stable.ppm

The resulting stabilized sequence would be: 

0.ppm, 1.stable.ppm, 2.stable.ppm, ..., 9.stable.ppm

Option Syntax

--replace         Replace overlapping areas rather than merging.
--no-replace      Do not replace.  [default]

Alignment

Alignment compares each supplemental frame in the sequence with an intermediate rendering known as the accumulated image. Based on this comparison, a transformation is assigned to the supplemental frame. Many different transformations can be assigned before alignment of the frame is complete.

Match statistics

The match statistic is a single number indicating how well two frames are aligned. After alignment is complete, ALE displays the final match statistic. If the value is close to 100%, then the frames are well aligned. Very low values can indicate misalignment. However, even frames that are very well aligned do not usually achieve 100% alignment, and for improving image quality, ALE works most effectively when match values are less than 100%.

Match threshold

A match threshold can be specified; no images with final match statistics falling below this threshold will contribute to the final output. 
--threshold=x     Min. match threshold; a perfect match is 100.  (0 is default)

Error metric exponent

The function calculated at each pixel to determine the match statistic is known as the error metric, and is of the form (a-b)x. The value x is known as the error metric exponent, and is 2 by default. Larger numbers usually mean that alignment will be more influenced by smaller image features. 
--metric=x        Set the error metric exponent.                 (2 is default)

Alignment Channel Options

In calculating the per-pixel error metric, there are three ways in which ALE can handle color channels. By default, ALE adds the channels before calculating the match. However, ALE can also rely solely on the green color channel or use all three channels separately. 
--align-all       Align images using all color channels
--align-green     Align images using the green channel
--align-sum       Align images using a sum of channels [default]

Monte Carlo Alignment

Aligning large images can take a very long time if all pixels are examined in determining the match statistic, so it is often desirable to examine a smaller number of pixels. The Monte Carlo alignment option allows this. The number of pixels used is specified as a percentage, and smaller numbers usually mean faster, but less precise, alignment. 
--mc <x>          Align using, on average, x% of available pixels (0 < x < 100)
--no-mc           Align using all pixels.  [default]

Perturbation

Every dot displayed after an input filename indicates a change in perturbation size. The size is initially set to be high, allowing large changes in alignment to be evaluated, and is reduced as the locally optimal alignment is found for each size. When this size drops below a specified lower bound, the frame is considered to be aligned.

Perturbation bounds

These options determine the upper and lower bounds for perturbation size. The perturb-upper and perturb-lower bounds apply to rotation (in degrees), translation (in pixels), and the movement of the boundaries of a projected frame (in pixels). The rot-upper bound disables rotational perturbation above a certain perturbation size (in degrees). To disable alignment, set perturb-upper to zero. 
--perturb-upper=x Perturbation upper bound in pixels/degrees  (32.0 is default)
--perturb-lower=x Perturbation lower bound in pixels/degrees  (.125 is default)
--rot-upper=x     Rotation-specific perturbation upper bound  (32.0 is default)

Level of detail

Alignment at large perturbation sizes is usually carried out on reduced-detail images. To disable this, set lod-max to log2(perturb-upper). 

--lod-max=x       LOD scale factor is max(1, (2^floor(x))/perturb)  (1 is def.)

Transformations

The variables used to adjust alignment are called transformations, and map points from a source image to a target image.

There are three transformation classes that can be used by ALE. The translational class applies only translations to the inputs, changing only the position of images; the Euclidean class applies translations and rotations; and the projective class applies general projective transformations, which are the most general type of transformation supported by ALE.

The Euclidean class is most appropriate for use with scanners and as a first pass for projective transformations. The projective class is most appropriate for use with cameras.

Except when capturing flat scenes, ALE does not correct for perspective changes, so movement of cameras should ideally be constrained so that no large translations occur.

Transformation Class Options

--translation     Only adjust the position of images
--euclidean       Adjust the position and orientation of images [default]
--projective      Use projective transformations.  Best quality, but slow.

Transformation data file options

Transformations used in alignment can be loaded from a file or saved to a file. This can be useful when performing alignment in several passes, or when refining rendering options.

Note that projective transformation data saved to a file cannot be used to initialize other transformation types. 

--trans-load=x    Load initial transformation settings from file x
--trans-save=x    Save final transformation data in file x

Alignment following

When frames are more closely aligned with adjacent frames in the sequence than they are with the first frame in the sequence, alignment success can be improved by specifying the --follow option. This option can be effective even when initial alignment information is loaded from a file. 
--identity        Frames align closely with the original frame.  [default]
--follow          Frames align closely with their immediate predecessor.

Irani-Peleg Renderer

ALE implements an iterative image reconstruction algorithm based on Michal Irani and Shmuel Peleg's paper "Improving Resolution by Image Registration", published in Graphical Models and Image Processing, Vol. 53, No. 3, May, pp. 231-239, 1991, or available at:

http://www.wisdom.weizmann.ac.il/~irani/abstracts/superResolution.html

This algorithm iteratively performs two steps: first, an approximation of T is projected, based on a filter approximating dj, and data collected during alignment, to create a set of simulated input frames; second, the per-pixel error -- between these simulated input frames and the actual input frames -- is calculated, backprojected, and subtracted from the approximation of T, resulting in a new approximation of T.

Initial Image Approximation

ALE uses the results of previous rendering steps as the initial image approximation.

Projection and Back-projection filters

ALE provides command-line options for selecting forward-projection filters, including box filters (release 0.4.2 and later) and custom filters (release 0.4.7 and later). The back-projection filters are constructed from the forward-projection filters in such a way that condition (9) from Theorem 4.1 in the source paper is satisfied.

Transformation details

ALE's method of transforming pixel areas between coordinate systems approximates transformed pixel boundaries with axis-aligned rectangular regions. Since boundaries are transformed into the coordinate systems of the input frames, this approximation can be improved by using larger scale factors (and hence reducing the size of transformed pixels).

Multi-level operation

The following is an edited excerpt from the comment headers for the source file d2/render/ipc.h. For more information about ALE's implementation of multi-level operation, see the relevant source files.

ALE Version 0.6.0 Technical Description

Abstract

ALE combines a series of input frames into a single output image possibly having:

  • Reduced noise.
  • Reduced aliasing.
  • Increased tonal resolution.
  • Increased spatial resolution.

This page discusses related work, models of program input, renderers used by ALE, the alignment algorithm used, an overview of the structure of the program, and examples for which the above output image characteristics are satisfied.

ALE's approach to exposure registration and certainty-based rendering is not discussed in the current version of this document. See the source code for implementation details.

Related Work

The drizzling renderer used in ALE is based on Richard Hook and Andrew Fruchter's drizzling technique.

Steve Mann's discussions (e.g. here and here) of increased spatial extents, projective transformations, image processing on linear data, and weighting by certainty functions, have influenced features incorporated by ALE.

ALE incorporates an iterative solver based on Michal Irani and Shmuel Peleg's iterative deblurring and super-resolution technique (see here).

Camera Input Frame Sequences

For positive integer N, a sequence of camera snapshots { K1, K2, …, KN }, defined by the triples { Kj = (Sj, Vj, dj) } is a camera input frame sequence if, for all j and j', Sj = Sj'.

Projective transformations

A projective transformation is a transformation that maps lines to lines. For more details, see:

Heckbert, Paul. "Projective Mappings for Image Warping." Excerpted from his Master's Thesis (UC Berkeley, 1989). 1995. http://www.cs.cmu.edu/afs/cs/project/classes-ph/862.95/www/notes/proj.ps

Projective Snapshots

A projective snapshot is defined as an n-tuple consisting of:

  • A continuous image Σ.
  • A projective transformation q with restricted domain, such that composite(Σ, q) ∈ CC
  • A function d: CC → DD.

Projective Input Frame Sequences

For positive integer N, a sequence of projective snapshots { P1, P2, …, PN }, defined by the n-tuples { Pj = (Σj, qj, dj) }, is a projective input frame sequence if, for all j and j', Σj = Σj'.

The first frame in the sequence of input frames is called the original frame, and subsequent frames are called supplemental frames.

Construction of Projective Input Frame Sequences from Camera Input Frame Sequences

Given a camera input frame sequence { Kj = (S, Vj, dj) }, if there exists a continuous image Σ and a sequence { qj } of projective transformations with restricted domain such that, for all j, Vj(S) = qj(Σ), then this camera input frame sequence admits a corresponding projective input frame sequence { Pj = (Σ, qj, dj) }.

Informally, two cases where such construction is possible for an ideal pinhole camera are:

  • A sequence of frames taken from a fixed position in space, but with variable orientation.
  • A sequence of frames depicting a single flat, diffuse surface, taken from arbitrary positions and orientations.

For more information about the properties of projective transformations, see the first of Steve Mann's papers referenced in the Related Work section above.

Projective Renderer without Extension

For a projective input frame sequence { Pj = (Σ, qj, dj) }, a projective renderer without extension is an algorithm that outputs a discrete image approximation of composite(Σ, q1). The assumptions used in calculating the approximation vary across rendering methods.

Projective Renderer with Extension

For a projective input frame sequence { Pj = (Σ, qj, dj) }, a projective rendering method with extension is an algorithm that outputs a discrete image approximation of composite(Σ', q1'), where q1' extends the domain of q1 so that its range is a superset of the domain of Σ, and Σ' extends Σ to match the range of q1'. The assumptions used in calculating the approximation vary across rendering methods.

Renderers

Extension

All renderers can be used with or without extension (according to whether the --extend flag is used). The target image for approximation (either composite(Σ, q1) or composite(Σ', q1')) is generically called T.

Renderer Types

Renderers can be of incremental or non-incremental type. Incremental renderers update the rendering as each new frame is loaded, while non-incremental renderers update the rendering only after all frames have been loaded.

Incremental renderers contain two data structures that are updated with each new frame: an accumulated image A with elements Ax, y and the associated weight array W with elements Wx, y. The accumulated image stores the current rendering result, while the weight array stores information about contributions to each accumulated image pixel.

Renderer Details

These pages offer detailed descriptions of renderers.

Rendering Predicates

The following table lists predicates which may be useful in determining whether the discrete-image output of a rendering method approximates T. The section following this lists, for each renderer, a collection of predicates which should result in T being approximated.

Predicate Explanation
Alignment The projective input frame transformations qj are known.
Translation All projective input frame transformations qj are translations.
Point sampling (∀j) (∀x ∈ Domain[qj]) (dj(composite(T, qj))(x) = composite(T, qj)(x)).
Box Filter Approximation An acceptable discrete approximation of T can be achieved by partitioning it into a square grid and representing each square region by its mean value.
Jittering Assumption 1 The average of several point samples drawn uniformly from a region of T is an acceptable approximation for the mean value of the region.
Jittering Assumption 2 Each region in T corresponding to an output pixel has been sampled several times at points drawn uniformly from the region.
Small radius The radius parameter used for drizzling is chosen to be sufficiently small.
Barlett filter approximation Convolution of T with a Bartlett (aka triangle) filter remains an acceptable approximation of T.
Linear PSF only There is no non-linear PSF component.
USM approximation The Unsharp Mask technique provides an acceptable approximation of the inverse convolution for the given linear point-spread function.
Correct PSF The behavior of dj is equivalent to convolution with the given point-spread functions.
Low Response Approximation Frequencies to which dj has low response need not be accurately reconstructed in the program output.
Convergence The Irani-Peleg technique converges to the desired output for the given input sequence. This condition is proven for special cases in the source paper.

Rendering Predicates by Renderer

For each renderer, the following table gives a collection of rendering predicates that should result in rendered output being an acceptable approximation of T. Note that renderers may produce acceptable output even when these predicates are not satisfied. Justification for the entries in this table should appear in the detailed descriptions; if this is not the case, then the values given should be considered unreliable.

Space Complexity

Image storage space in memory for all renderers without extension is O(1) in the number of input frames and O(n) in the number of pixels per input frame. The worst-case image storage space in memory for all renderers with extension is O(n) in the size of program input.

Alignment Algorithm

Details on the alignment algorithm used in ALE are here.

Program Structure

First, a merging renderer is instantiated. Then, program flags are used to determine what other renderers should be instantiated.

An iterative loop supplies to the renderers each of the frames in sequence, beginning with the original frame. The drizzling and merging renderers are incremental renderers, and immediately update their renderings with each new frame, while the USM and Irani-Peleg renderers do not act until the final frame has been received.

In the case of the incremental renderers, the original frame is used without transformation, and each supplemental frame is transformed according to the results of the alignment algorithm, which aligns each new frame with the current rendering of the merging renderer.

Once all frames have been aligned and merged, non-incremental renderers produce renderings based on input frames, alignment information, and the output of other renderers.

Examples

Sections below outline examples of cases in which output images satisfy various criteria.

For a projective input frame sequence { Pk = (Σ, q, dk) }, these examples use the shorthand

I = composite(Σ, q)
and
Dk = dk(I).

Reduced Noise

Assume a projective input frame sequence { Pk } of K frames, defined by n-tuples { Pk = (Σ, q, dk) }, such that (∃a > 0) (∀x ∈ Domain[q]) (∀y ∈ {R, G, B}) (I(x)y > a/2) and, for one such a, (∀x) (∀y) (Dk(x)y = I(x)y + nk,x,y), where nk,x,y are i.i.d. additive noise terms having uniform distribution over the interval (-a/2, a/2).

In this case, rendering input frames by merging or drizzling averages the additive noise terms of the input images to produce an output additive noise term; when K ≥ 2, this output noise has a smaller expected absolute value than that of any given input noise term.

To prove this, first observe that rendered output image O (for drizzling or merging) averages the K inputs with equal weight:

O(x)y = ∑k (Dk(x)y / K)
Substituting for Dk:
O(x)y = ∑k [(I(x)y + nk,x,y) / K]
Moving the constant outside of the sum:
O(x)y = (I(x)y / K) * K + ∑k (nk,x,y / K)
O(x)y = I(x)y + ∑k (nk,x,y / K)
The last term in the equation above is the noise term for the output image. Leaving location and channel implicit, the expected absolute value for this term is:
Eout = E[|∑k (nk / K)|]
Since there is nonzero probability that both strictly negative and strictly positive terms appear in the sum, this gives rise to the strict inequality:
Eout < E[∑k |nk / K|]
By linearity of expectation, this is equivalent to:
Eout < ∑k E[|nk / K|]
Eout < ∑k E[|nk|] / K
Since the input noise distributions are identical, this reduces to:
Eout < Ein * K / K
Eout < Ein
where Ein = E[|nk|] for any choice of k.

Reduced Aliasing

Assume that an image has been sampled at the highest frequency to which the sensors respond (i.e., half of the Nyquist frequency), resulting in aliasing, and that four such images are available, dithered (i.e., in this case, translated) so that the collection of samples from all images forms a regular grid with twice the sampling rate of the original image. Rendering these four images with correct alignment into an output image having the same dimensions as this grid results in an image with no aliased frequencies.

Increased Tonal Resolution

Assume a projective input frame sequence { Pk } of K frames, defined by n-tuples { Pk = (Σ, q, dk) }, such that components of I assume a real value in the interval [0, 1] and (∀ x, y, k) (Probability[Dk(x)y = 1] = 1 - Probability[Dk(x)y = 0] = I(x)y]).

Since the transformations of all frames are identical, rendering with merging or drizzling averages the values for each pixel Dk(x) over all values of k. Since the expected value of Dk(x) is equal to I(x), the expected value of the corresponding pixel in the rendered output is always equal to I(x). However, the probability of obtaining a value within a small neighborhood of I(x) is generally not high for small numbers of frames.

As the number of frames increases, however, the probability of obtaining a value within a neighborhood of any given size approaches 1. Hence, arbitrarily high tonal resolution can be achieved with arbitrarily small (but non-zero) likelihood of error. The exact probability can be determined according to the binomial distribution.

(The above constitutes an outline of a proof, but there may be holes in it.)

Increased Spatial Resolution

The reduced aliasing example, above, serves also as an example of increased spatial resolution.

Increased Spatial Extents

Assume a projective input frame sequence such that each snapshot can be associated with a point in the scene invisible from that snapshot, but visible from some other snapshot.

In this case, for every snapshot in the input sequence, the output rendering will include at least one point not present in that snapshot.

Merging

Merging uses bilinear interpolation to determine each frame's contribution to the accumulated image, with each contribution assigned equal weight. Where bilinear interpolation does not define a value, the accumulated image pixel is not updated. Sections below outline the properties of this approach.

Properties

Convolution with the Bartlett (triangle) filter as the limiting case

Assuming predicates for translation and point sampling, bilinear interpolation is equivalent to convolution with a Bartlett filter. Combined with the box filter approximation, jittering assumptions, and Bartlett filter approximation, the result of merging should be an acceptable approximation of T. This should be proven at some point. Until then, this result should be considered unreliable.

Density and false local minima

Informally, the merging method outlined above always updates a dense set of pixels in the accumulated image. In particular, any accumulated image pixel whose center falls on a line between updated pixels is also an updated pixel.

It is conceivable that this property reduces the likelihood of alignment failure due to entrapment in local minima; hence, the merging renderer is always used as a reference for the alignment algorithm. Except in cases where a large radius is used, drizzling does not share these properties.

USM Renderer

The Unsharp Mask Renderer is a built-in post-processing step based on the unsharp mask technique, which has been used to enhance high frequencies since the days of photographic plate processing (see, for example, this page). This renderer acts after all other rendering steps have completed, except for Irani-Peleg rendering, which occurs afterward.

Properties

Given a sequence of images that satisfy all predicates for merging (or drizzling) except point sampling; given a known linear PSF; and given only translations between frames, the result of merging (or drizzling) will be an acceptable approximation of T convolved with the PSF. This does not imply that deconvolution of this result will be an acceptable approximation of T, however, since frequencies with low response may be reconstructed with poor fidelity due to reduced precision. We use the low-response approximation to ignore these frequencies. Assuming the USM approximation, the remaining frequencies are reconstructed to form an acceptable approximation of T. (Since this doesn't really constitute a proof, the results should be considered unreliable.)

Alignment

ALE aligns each supplemental frame, in sequence, with the merged rendering representing all previous frames. This page outlines the three supported transformation classes, the algorithm used for alignment, and the properties of the alignment algorithm. Following this is a discussion of practical use of alignment options, including alignment classes and alignment in the case of extended renderings.

Transformations

ALE offers three classes of transformations:

Translationsintroduced in version 0.0.0
Euclidean transformations (excluding reflections)introduced in version 0.1.0
Projective transformationsintroduced in version 0.2.0

Algorithm

Alignment proceeds by a deterministic search, beginning with an initial transformation and modifying this transformation through a series of perturbations.

The initial transformation may be loaded from a file or selected by default. The default initial transformation is either the identity transformation or (when the --follow option is specified) the most recently merged frame's final alignment. (Note that changes in release 0.5.0 are not reflected here; these changes affect the interaction of the --follow and --trans-load flags.)

Once the initial transformation is determined, an initial perturbation amount is selected, and represents the step size by which each of the transformation parameters are changed. In translational or Euclidean alignment, the perturbation amount is applied to translation -- in units of pixels on the two image axes -- and rotation -- in units of degrees about the image center. (In version 0.4.8 and later, an additional configurable upper bound constrains rotational perturbation separately, preventing, e.g., a 360 degree perturbation of rotation.) In the case of projective alignment, the perturbation amount is applied to the position of the corners of the projected quadrilateral in units of pixels, where the projection is from the boundary of the supplemental image into the coordinate system of the accumulated image.

If possible, transformation parameters are changed to decrease the error between the two images being aligned. The perturbation amount is halved whenever it is determined that no parameter change of this size improves the alignment of the images. A lower bound on the perturbation amount determines when the alignment is complete.

The order in which parameters are considered for change is specified in the source code, and has the following property: No modified parameter is considered for further change until all other parameters have been considered. A consequence of this property is that parameters are always considered in a fixed (round robin) order.

When multiple levels of detail are used, the error may be calculated on images with a reduced level of detail. ALE versions 0.1.1 through 0.4.7 use a level of detail twice as fine as the perturbation amount for perturbation amounts larger than two, and full detail otherwise. Later versions default to this behavior, but can be configured differently. Earlier versions do not use reduced levels of detail.

Properties

Several assumptions were made throughout the design and testing of the algorithm outlined above. These assumptions are outlined below.

The algorithm is based on a hill-climbing approach, which requires that any local minimum reachable from the starting point by traveling a path of decreasing error is also a global minimum (or, in this case, the correct alignment). While it is possible that the algorithm outlined above succeeds in some cases for which hill-climbing fails, it is still susceptible to entrapment in local minima.

As outlined above, depending on program options, transformation parameters may be changed by perturbations of several units (degrees or pixels) early in the alignment process. As long as no change of this magnitude moves the transformation out of the 'bowl' in which the minimum error -- and hence correct alignment -- lies, this is not a problem. However, it might break in some cases where a hill-climbing approach would succeed. (Notably, simulated annealing suffers from a similar problem, and it seems likely that a case could be constructed in such a way that the algorithm outlined above -- like simulated annealing -- could, contrarily, succeed where hill-climbing fails.)

Finally, the use of reduced level-of-detail relies on a high signal-to-noise ratio at low frequencies. Fortunately, this assumption seems to generally hold, but camera defects or radio interference could violate the assumption, possibly resulting in misalignment.

Use of Alignment Classes

ALE is likely to be most useful when corresponding regions of different frames can be aligned by one of the available alignment classes.

As described by Steve Mann in his work on Video Orbits, the projective transformation offers particular versatility for camera imaging of (ideal Lambertian) flat scenes. In this case, any change in camera position and orientation can be corrected as long as points always have a defined projection onto the rendering plane (for which ALE uses the base of the pyramid R1).

In camera imaging of scenes with depth, correction for orientation is almost the same as for flat scenes, since, if focus and lens distortion is ignored, a scene with depth is indistinguishable from a flat scene from the perspective of a camera whose position is fixed.

For sequences of camera images with small changes in position or orientation, the projective transformations for alignment may closely approximate Euclidean transformations; in this case, using Euclidean transformations may achieve similar results and may require less time for alignment, since there are fewer parameters to tweak (three parameters instead of eight).

In the case of flatbed scanners that preserve the relative height and width of scans, any change in the position or orientation of flat objects can be corrected using the Euclidean alignment class.

If a flatbed scanner does not preserve relative height and width, but does preserve straight lines, then any change in the position or orientation of flat objects can be corrected with the projective alignment class.

However, even if a transformation is within the alignment class used, the alignment algorithm may still be unable to approximate it.

Alignment in the case of Extended Renderings

By using the --extend flag, ALE can be used to create image mosaics spanning a spatial region larger than that represented by any single image in the frame sequence. In these cases, if adjacent frames in the sequence tend to be more closely aligned with each other than they are with the original frame, it may be helpful to also use the --follow flag as a hint to the alignment algorithm.

Monte Carlo Error Function

Monte Carlo alignment can decrease the time required to align large images, since performing coordinate transformations and memory accesses at every pixel can be expensive. Sections in this page describe the motivation for Monte Carlo alignment, the ratio calculations used, the sampling algorithm, cache behavior for the algorithm, randomization approaches, typical deviations from the specified ratios, special handling of level-of-detail, and practical observations regarding the use of Monte Carlo alignment.

Motivation

Performing large numbers of coordinate transformations and memory accesses in order to determine alignment error can be computationally expensive. One approach to mitigating this expense is to use reduced level-of-detail. However, using reduced level-of-detail can also reduce alignment precision. In particular, reducing the level of detail by a factor of two can make impossible the task of precisely aligning a horizontal line one pixel high. However, if just a few pixels from the line are sampled at full detail, exact alignment is possible.

Ratio Calculations

In Monte Carlo alignment, a ratio

s = (expected # of pixel samples) / (# of total pixels in the accumulated image)
is specified. From this ratio, a new ratio
u = (expected # of unsampled pixels) / (expected # of sampled pixels)
is calculated. Pixels are sampled in such a manner that u is approximately satisified.

At this stage, the region of overlap with the new frame is not considered. With a limited area of overlap, the number of actual samples contributing to the final error value will typically be reduced proportionally. (Angelo Pesce has pointed out that better approaches may be possible, wherein explicit calculation of overlapping areas reduces the number of coordinate transformations performed.)

Sampling Algorithm

Pixels are considered in order of index, where the accumulated image pixel at position (i, j) is numbered with an index (i * width + j). In order of index, we skip and sample pixels in such a manner that the expected size of a run of consecutive skipped pixels preceding a sampled pixel is u. We select the size of each run of consecutive skipped pixels as follows:

If 2 * u is an integer, then we draw uniformly from integer values in the interval [0,2u]. If it is not an integer, then we draw from integer values in the interval [0,2u + 1] in such a manner that integer values in [0,2u] are equally likely to be chosen. (There is only one probability distribution of this kind that satisfies the expected value u. Version 0.4.3 deviates slightly from this distribution, and so a deviation in the expected value of s occurs, as outlined in this table. This problem is fixed in version 0.4.4.)

(Also, see the section below on interaction with level-of-detail.)

Cache behavior

Since indices are monotonically increasing in memory address, this approach to sampling may make effective use of memory cache where other approaches (e.g. repeated random draws from the entire index space) would not.

Randomization

ALE versions 0.4.7 and earlier do not reseed the pseudorandom number generator, and so a new random subset is selected every time the error function is evaluated. Hence, as more or fewer of the pixels critical to alignment are sampled, the reported alignment can worsen or improve even in the absence of any change in transformation.

With this approach, since many transformations are inspected during the alignment of any given frame, it is likely, especially with greater precision of alignment, that some measured differences between transformations are due to a difference in sample sets rather than a difference in alignment accuracy.

By reseeding the pseudorandom number generator, ALE versions 0.4.8 and later instead use a consistent set of pixels from the accumulated image when comparing two transformations. Tests sampling 3% of pixels from a set of 320x240 frames indicate that this approach improves alignment.

Sampling characteristics

For an image with 100,000 pixels and specified s in the interval [0.005,0.995], ALE's sampling method results in a ratio s within 0.000003 of the specified s. This number improves with image size. These results are outlined in the table linked above. However, note that s only represents an expected value, and the actual number of sampled pixels may vary by more than the numbers given here.

Interaction with level-of-detail

When reduced level-of-detail is used, the number of reduced-detail pixels sampled is taken to be a percentage of the total number of pixels in the full-detail image, rather than as a percentage of the total number of pixels in the reduced-detail image. (When this fraction of pixels in the full-detail image is more than the number of reduced-detail pixels available, all reduced-detail pixels are used.) This may improve the likelihood of successful alignment, but may also add overhead to the alignment process.

Use of Monte Carlo Alignment

If it is not known in advance what settings will work well for a series of frames, it may be desirable to begin by sampling a small percentage of pixels, saving the results of alignment, and then, if the output suggests that proper alignment is occuring, performing more precise alignment with a larger percentage of pixels on later passes, using smaller perturbation upper bounds. If alignment problems occur on the first pass, the percentage of pixels can be increased and alignment performed again.

Error Functions

Error Functions



Error functions are used to determine whether a transformation is "good" or
not, and in particular, whether one transformation is better or worse than
another.  In particular, a smaller error indicates a better transformation.




ALE defines error functions for each pixel of the accumulated image, and
also a comprehensive error function that summarizes the error over all 
pixels.  


Pre-Alignment Exposure Registration



When exposure registration is enabled, ALE performs an exposure registration
step prior to alignment.  The resulting values are dependent on the initial
alignment (this can be either the default initial alignment or an alignment
loaded from a transformation data file).  See the source code for details.


Per-Pixel Error Functions






The per-pixel error function for pixel (i, j) in the accumulated
image A, frame B, and transformation T, is:




p(i, j, A, B, T) = Abs( A(i, j) - B(T_inverse(i, j)) )metric_exponent






where Abs() is the absolute value function and B(T_inverse(i,
j)) is determined by bilinear interpolation.  If not specified by the
--metric option, metric_exponent defaults to 2.0 for ALE versions 0.1.0
and later, or 1.0 for version 0.0.0.


For coordinates where B(T_inverse(i, j)) is not defined, the error is zero.
(Feedback from Angelo Pesce led to clarification of this point.)


In addition to the per-pixel error function, a per-pixel maximum error
estimator is calculated, as follows:




p_max(i, j, A, B, T) = Max( A(i, j), B(T_inverse(i, j)) )metric_exponent






For coordinates where B(T_inverse(i, j)) is not defined, the maximum error
estimator is zero.  (Feedback from Angelo Pesce led to clarification of this
point.)



Comprehensive Error Functions


There are two varieties of comprehensive error function used by ALE: an
exhaustive error function and, in versions 0.4.3 and later,  a
Monte Carlo error function.  Whereas the exhaustive function
evaluates the error for each pixel in the accumulated image, the Monte
Carlo function evaluates only a subset of pixels.  

If we consider Sum[] to provide the sum over whatever
subset of pixels we are sampling (including possibly the set of all pixels), then
the comprehensive error function, for accumulated image A, frame
B, and transformation T, is:




E(A, B, T) = (Sum [ p(i, j, A, B, T) ] / Sum [ p_max(i, j, A, B, T) ])(1/metric_exponent)

Drizzling Renderer



ALE versions 0.4.1 and later implement a drizzling algorithm based on that
outlined in research by Richard Hook and Andrew Fruchter.1  


Algorithm



In the drizzle rendering method, pixels from source images are associated
with a square region of given radius in the source image coordinate system.
Similarly, each pixel in the accumulated image, or target image, is associated
with a square region, such that each square region coincides with its neighbors
exactly at its edges.  The source regions are then transformed according to the
known alignment between source and target, and the regions from all transformed
source images are combined to form the target image, where each source pixel
region contributes to each target pixel region linearly with the area of
overlap between the regions (as calculated in the target coordinate system).


ALE uses an approximation to the above approach, wherein the area of overlap
is calculated in the coordinates of the source image and then multiplied by a
factor approximating any difference in scale between the source and target
images; for the purpose of these calculations, the region of the target pixel
is approximated by a rectangle in the source coordinate system having all sides
parallel to the source image coordinate axes.


Properties



Assuming small drizzling radius, drizzling is approximately the same as
convolution of discrete pixel data with a box filter having the same radius as
the chosen drizzling radius.  Given the box filter approximation, jittering
assumption, point sampling, and sufficiently small radius, drizzling should
provide an acceptable approximation of T.  Until this is proven,
however, this result should be considered unreliable.

"Variable-Pixel Linear Combination", published in vol. 125 of the ASP
Conference Series (eds. Gareth Hunt and H. E. Payne).  This paper was also

ALE Version 0.7.x/0.8.x Technical Description  



Purpose



This page discusses motivation, related work, models of program input,
renderers, and the alignment algorithm, but does not cover the 3D scene
reconstruction code in versions 0.7.2 and later.  Note also that some changes
in 0.8.x might not yet be covered.  For information on ALE program operation and
usage, see the User Manual for 0.7.x or 0.8.x.



Note: This document uses HTML 4 character entities.  Sigma is 'Σ'; summation is '∑'.



Motivation



Several factors in the imaging pipeline can affect output, sometimes
degrading image quality, either individually or through combination.  Lens
effects include barrel or pincushion distortion; the camera sensor and
electronics can produce blurring, signal aliasing, noise, quantization, and
non-linear effects; analog video signals can degrade in transmission; and
various compression techniques and digital enhancements on- or off-camera can
destroy image features.  In some cases, a better image can be produced through
combining information contained in different images.







Imaging Pipeline





Related Work



Richard Hook and Andrew Fruchter's drizzling technique was designed
to combine dithered undersampled images.  Previous versions of ALE supported this
technique; the current version supports an approximation.


Steve Mann's work (e.g. here and here), on spatial extents,
projective transformations, linear-colorspace image processing, and weighting
by certainty functions, motivated ALE's adoption of these features.  A
modified, "one-sided" approach to certainty is used by ALE's Irani-Peleg
renderer, to better accommodate extremely bright features that exceed the range
of all input images.  This approach is modified further in 0.8.0 to rely on
estimated (instead of measured) intensities, which may allow further reduction
of noise in some cases.


ALE incorporates an iterative solver based on Michal Irani and Shmuel
Peleg's iterative
deblurring and super-resolution technique.  It has been extended to handle
convolutions occurring in tandem in different colorspaces, and has been
modified for certainty weighting.


ALE's treatment of barrel distortion, using a polynomial in distance from
the image center, is based on that of Helmut Dersch's Panorama Tools.  ALE's
approach adjusts the linear (first-order) coefficient so that the corners of
the transformed frame remain in place.



Program Inputs



Define an image to be a function mapping a subset of 2D Euclidean space to
an RGB colorspace; define a discrete image to be an image defined only
at coordinates having integral components; define a spatial discretization 
to be an operator that restricts the domain of an image to a set of points
having integral components, thus producing a discrete image; define a spatial
extension to be an operator that extends the domain of a discrete image by 
assigning the value of the nearest neighbor point.


Ignoring noise and color quantization, ALE assumes that each input frame
dx is a discrete image that can be obtained by applying a
sequence of operators, including transformations, exposure adjustment,
convolutions, gamma correction, spatial discretization, and spatial extension,
to some image d, as follows:



dx = DNCGDLExBxPxd



Where:


    

  • Px is a projective transformation

  • Bx is a barrel/pincushion distortion transformation

  • Ex is linear exposure adjustment

  • L is a convolution in linear colorspace

  • D is a spatial discretization

  • G is gamma correction

  • C is a spatial extension

  • N is a convolution in non-linear colorspace



(When ALE aligns using Euclidean transformations, Px are
assumed to be Euclidean.)


The presence of an extension operator between G and N is
suspect, and is somewhat inelegant in the case of digitally processed data, but
although such extension may require careful selection of N, it does not
restrict the set of possible models.  It is only included because it creates a
parallelism between N and L that makes implementation easier.
In a more sophisticated implementation, it could be removed.



Incremental Rendering



If L and N are assumed to behave as identity operators, then each
pixel in each input frame corresponds to a single point in d.  In this
case, it may be possible to apply filtering operations to input frame pixels
directly.  One caveat, however, is that different parts of the output may be
sampled with unequal density in the input frame sequence; hence, a filtering
approach that is uniform over all regions could cause significant aliasing or
detail loss.  Instead, ALE uses a non-uniform approach.  If In(i,
j) is an output pixel, at position (i, j), updated for input frames
zero through n, then:



In(i, j) = ∑n'∈0..n∑(i',j')∈Dom[dn'] En'-1G-1dn'(i',j') * c(n, n', i, j, i', j', E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn)




Where c is a rendering chain.  Note that for most
types of rendering chains, the above expression can be simplified considerably.


Irani-Peleg Rendering


ALE's Irani-Peleg renderer iteratively updates the final output of incremental
rendering, with update operator U:



J0 = Ifinal


J1 = UJ0


.


.


.


Jk = UJk-1



Where U is the Irani-Peleg update rule.


Spatial Extension and Space Complexity



By default, the output image is of fixed size, limited to the extents of
d0, the first image in the input sequence; the 'extend' option
specifies that output should accommodate all regions of all input images.


When rendering an output image of fixed size, image storage space in memory
for all non-median rendering types is O(1) in the number of input frames
and O(n) in the number of pixels per input frame, since at most one
input image is loaded into memory at any time.  For median-value rendering,
storage is O(n) in the number of input frames.  When using projectively-aligned
input images, however, renderings that accommodate all regions of all input
images can generate arbitrarily large output for a bounded input size, and can
use an arbitrarily large amount of memory.


Alignment Algorithm



Details on the alignment algorithm used in ALE are here.



3D Scene Reconstruction



The scene reconstruction code is still very experimental and is not
currently covered by this document.  For more information, see the user manual
and source code.

ALE Irani-Peleg Update Rule


The Irani-Peleg update operator U is used iteratively to update the
final output of incremental rendering:



J0 = Ifinal


J1 = UJ0


J2 = UJ1


.


.


.


Jk = UJk-1




Modeling of the imaging process



Given transformations Px and Bx, linear
exposure adjustment Ex, linear and non-linear convolutions
L and N, discretization operator D, and extension operator
C, the imaging process can be modeled, starting with s, a
discrete approximation of the scene, as:



dx = DNCGDLExBxPxCs




Note the extension operator to the left of s, which was not present
in the similar equation appearing on the main page.  Since we are using only a
discrete approximation of the scene, it must first be made continuous, in order
to fit within the framework developed on the main page.  As noted before, the
second extension operator, between G and N, is included for
convenience of implementation, and does not restrict the generality of the model.


Pixel-to-pixel weighting



Since pixel values in DLExBxPxCs are
linear in pixel values of Cs, and hence linear in pixel values of
s, and since, similarly, pixel values of dx are linear
in pixel values of GDLExBxPxCs, we can
define arrays of values a and b such that:



DLExBxPxCs(i, j) = ∑(i', j') ax,i,j,i',j' * s(i', j')



dx(i, j) = ∑(i', j') bx,i,j,i',j' * GDLExBxPxCs(i', j')



Hence, using G as a gamma correction function:



dx(i, j) = ∑(i', j') bx,i,j,i',j' * G(∑(i'', j'') ax,i',j',i'',j'' * s(i'', j''))



Note that, since G is non-linear, the inner sum cannot be moved outside of the enclosing parentheses.


Error calculation



Given the model described above, we now have two ways to calculate a pixel value dx(i, j): directly, from the input frame, or indirectly, from the scene approximation s.  Hence, we can calculate an error between the two methods:



ex(i, j) = dx(i, j) - ∑(i', j') bx,i,j,i',j' * G(∑(i'', j'') ax,i',j',i'',j'' * s(i'', j''))




Backprojection (single stage)


Assume for the moment that our model of dx were restricted in the following way, using a scene approximation s':



dx(i, j) = ∑(i', j') bx,i,j,i',j' * s'(i', j')




This includes, as a special case, the scenario originally outlined by Irani and
Peleg, which considered a single convolution step.  In this case, we can use a
backprojection array c to produce an updated image Us':



Us'(i, j) = s'(i, j) + (1 / xmax) * ∑x ∑(i', j') cx,i,j,i',j' * ex(i', j')




For certain limited cases, Irani and Peleg have proved this update rule to
converge exponentially to the original scene.  However, since the model used by
ALE includes two convolution steps that cannot, in general, be combined, ALE
uses a different update rule.


Backprojection (two-stage)



The two-stage backprojection rule below could easily be extended to any
arbitrary number of stages, but ALE currently supports only two stages, in
accordance with the two-colorspace imaging model outlined above.  The rule,
using G-1 as an inverse gamma correction function, is:




Us(i, j) = s(i, j) + (1 / xmax) ∑x ∑(i', j') cx,i,j,i',j' * (G-1(GDLExBxPxCs(i', j') + ∑(i'', j'') fx,i',j',i'',j'' * ex(i'',j'')) - DLExBxPxCs(i', j'))




Where f is a second backprojection array.  Schematically, the update
process looks something like the diagram below, based on an excerpt from the
ALE source code.  The exposure re-estimation step shown in the diagram has not
been described here, but is available for inspection in the source.  Also,
since ALE stores images internally using a linear representation, they must
first be converted back to a non-linear representation, as shown at the very
bottom of the diagram.

Backprojection Arrays



The rules used for calculating backprojection arrays c and f are as follows:




cx,i,j,i',j' = Y * bx,i,j,i',j'



fx,i,j,i',j' = Z * ax,i,j,i',j'




Such that:





Y = - 0.9 / (maxω |FKb(ω)|)



Z = - 0.9 / (maxω |FKa(ω)|)




where F is the fourier transform, Ka is the convolution kernel for a
in its native coordinate system, and Kb is the convolution kernel for b in its native coordinate
system.


Convergence for special cases



In cases where at least one of L, N, or G is the
identity operator, or if G is linear, the technique outlined above can
be expressed in terms of the original method by Irani and Peleg, and will
converge exponentially if it meets the convergence criteria outlined in their
paper.  Note that ALE makes certain approximations to obtain projection and
backprojection arrays that may hinder convergence in some cases.  In particular,
the calculation of overlap areas involving non-identity transformations is not
exact.



Certainty



ALE's implementation of certainty for Irani-Peleg rendering modifies the rule
described above.  Write the original rule as:




Us(i, j) = s(i, j) + (1 / xmax) ∑x correctionx(i, j)




where correctionx represents the back-projected correction
for frame x.  Let the re-estimated linear value comp_real,
lreal(n) in the diagram above, be defined as:



comp_realx(i, j) = G-1(GDLExBxPxCs(i, j) + ∑(i'', j'') fx,i,j,i'',j'' * ex(i'',j''))



Then the certainty-based rule for versions 0.7.x is:



Us(i, j) = s(i, j) + ∑x Κ(correctionx, Excomp_realx, i, j) * correctionx(i, j) / ∑x K(correctionx, Excomp_realx, i, j)




Where Κ is the symmetrically one-sided certainty function.  


For version 0.8.0, the rule is:




Us(i, j) = s(i, j) + ∑x Κ'(correctionx, s, i, j) * correctionx(i, j) / ∑x Κ'(correctionx, s, i, j)




Where Κ' is the asymmetrically one-sided certainty function.  Note that this expression substitutes s for Excomp_realx, resulting in estimate-based certainty.

ALE Certainty



When used with a sequence of differently-exposed images, the certainty
techniques implemented in ALE may produce output having higher fidelity overall
than that of any single exposure.


Motivation



When multiple, differently-exposed images of the same scene are available,
variations of intensity visible in one image might not be visible in another.
In particular, if the difference between maximal light and dark values in the
scene exceeds the range of the image capture apparatus, then no single exposure
can faithfully record the scene.  Using multiple exposures allows discernment
of at least as many details as any single exposure in the set can provide, and
may allow discernment of more details, and better estimates of intensities.


Related Work



Steve Mann's original approach to certainty is described in his comparametric paper.  ALE extends
his approach to Irani-Peleg rendering by defining certainty for (intensity,
correction) pairs (in versions 0.7.x) and by basing certainty on estimated
intensities (in version 0.8.0).


Two-sided Certainty



Two-sided certainty operator κ is used by ALE's incremental
renderer, and applies a parameterized heuristic function:



κd(i, j) = max(0.001, [1 - 4 * (0.5 - d(i, j))2]k)



Where all operations are applied componentwise, and k is the certainty
exponent parameter.


Symmetrically One-sided Certainty



Symmetrically one-sided certainty is used by ALE's Irani-Peleg renderer in
versions 0.7.x, and is calculated using the direction of bias of a correction
c(i, j) against a modeled pixel value m(i, j).  The following
expression assumes the range of m to be [0, 1], and expresses
condition using the C trinary if-else operator:



Κ(c, m, i, j) = [c(i, j) * (m(i, j) - 0.5) > 0] ? 1 : κd(i, j)




Where all operations are applied componentwise, and κ is the
operator for two-sided certainty.



Asymmetrically one-sided certainty


Asymmetrically one-sided certainty applies the one-sided condition asymmetrically.



Κ'(c, m, i, j) = [c(i, j) > 0 && (m(i, j) - 0.5) > 0] ? 1 : κd(i, j)




Estimate-based Certainty



Estimate-based certainty uses an estimate of intensity, rather than measured
intensity, to determine certainty, and can be used in a one-sided or two-sided
way.  ALE version 0.8.0 uses estimate-based asymmetrically one-sided certainty
to weight Irani-Peleg correction values.

Alignment



ALE aligns each supplemental frame, in sequence, with an alignment
reference image constructed from previous frames.  This page outlines
supported transformation classes, the algorithm used for alignment, and the
properties of the alignment algorithm.  Following this is a discussion of
practical use of alignment options, including alignment classes and alignment
in the case of spatial extension.


Transformations



ALE offers the following classes of transformations: 





Translationsintroduced in version 0.0.0

Euclidean transformations (excluding reflections)introduced in version 0.1.0

Projective transformationsintroduced in version 0.2.0

Barrel distortion correctionintroduced in version 0.7.0




Algorithm



Alignment proceeds by a deterministic search, beginning with an initial
transformation and modifying this transformation through a series of
perturbations.


The initial transformation may be loaded from a file (when
--trans-load is used) or selected by default, or may be the
result of a global search (when --gs is used [0.7.1 only]).  The
default initial transformation is either the transformation of the original
frame (when the --identity option is specified) or the most
recently aligned frame's final alignment (when the --follow option
is specified).  When the initial transformation is loaded from a file, and if
the --follow option is specified, any changes to the alignment of
the previous frame are applied to the current frame at the outset.


Once the initial transformation is determined, an initial perturbation
amount determines the step size by which each of the transformation parameters
are changed.  In translational or Euclidean alignment, the perturbation amount
is applied to translation -- in units of pixels on the two image axes -- and
rotation -- in units of degrees about the image center.  An additional
configurable upper bound, --rot-upper, constrains rotational
perturbation separately, preventing, e.g., a 360 degree perturbation of
rotation.  In the case of projective alignment, the perturbation amount is
applied to the position of the corners of the projected quadrilateral in units
of pixels, where the projection is from the boundary of the supplemental frame
into the coordinate system of the alignment reference image.  In the case of barrel
distortion correction, the perturbation amount is scaled by a multiplier
(--bda-mult) before being applied to each barrel distortion
coefficient (if any have been defined).  The rate of change of barrel distortion
coefficients per frame can be limited with the option --bda-rate.


If possible, transformation parameters are changed to decrease the error between the supplemental frame and the alignment reference
image.  The perturbation amount is halved whenever it is determined that no
parameter change of the current perturbation size improves the alignment of the
images.  A lower bound on the perturbation amount determines when the alignment
is complete.




When multiple levels of detail are used, the error may be calculated on
images with a reduced level of detail.  By default, this version of ALE uses a
level of detail twice as fine as the perturbation amount for perturbation
amounts larger than two, and full detail otherwise.  This behavior can be changed
by adjusting the --lod-max option.

Monte Carlo Error



Use of Monte Carlo error can decrease the time required to align large images,
since performing coordinate transformations and memory accesses at every pixel
can be expensive.  Sections in this page describe the motivation for Monte
Carlo alignment, the ratio calculations used, the sampling algorithm, cache
behavior for the algorithm, randomization approaches, typical deviations from
the specified ratios, special handling of level-of-detail, and practical
observations regarding the use of Monte Carlo error.


Motivation



Performing large numbers of coordinate transformations and memory accesses in
order to determine alignment error can be computationally expensive.  One
approach to mitigating this expense is to use reduced level-of-detail.
However, using reduced level-of-detail can also reduce alignment precision.  In
particular, reducing the level of detail by a factor of two can make impossible
the task of precisely aligning a horizontal line one pixel high.  However, if
just a few pixels from the line are sampled at full detail, exact alignment is
possible.


Ratio Calculations



In Monte Carlo alignment, a ratio 



s = (expected # of pixel
samples) / (# of total pixels in the accumulated image)



is specified.  From this ratio, a new ratio 



u = (expected # of unsampled pixels) / (expected # of sampled pixels)



is calculated.  Pixels are sampled in such a manner that u is
approximately satisified.  


At this stage, the region of overlap with the new frame is not considered.
With a limited area of overlap, the number of actual samples contributing to
the final error value will typically be reduced proportionally.  (Angelo Pesce
has pointed out that better approaches may be possible, wherein explicit
calculation of overlapping areas reduces the number of coordinate
transformations performed.)


Sampling Algorithm



Pixels are considered in order of index, where the accumulated image pixel
at position (i, j) is numbered with an index (i * width + j).
In order of index, we skip and sample pixels in such a manner that the
expected size of a run of consecutive skipped pixels preceding a sampled pixel
is u.  We select the size of each run of consecutive skipped pixels as
follows:


If 2 * u is an integer, then we draw uniformly from integer values in
the interval [0,2u].  If it is not an integer, then we draw from integer values in
the interval [0,2u + 1] in such a manner that integer values in
[0,2u] are equally likely to be chosen.  


(Also, see the section below on interaction with level-of-detail.)


Cache behavior



Since indices are monotonically increasing in memory address, this approach
to sampling may make effective use of memory cache where other approaches (e.g.
repeated random draws from the entire index space) would not.  


Randomization



ALE versions 0.4.7 and earlier do not reseed the pseudorandom number generator,
and so a new random subset is selected every time the error is evaluated.
Hence, as more or fewer of the pixels critical to alignment are sampled, the
reported alignment can worsen or improve even in the absence of any change in
transformation.


With this approach, since many transformations are inspected during the
alignment of any given frame, it is likely, especially with greater precision
of alignment, that some measured differences between transformations are due to
a difference in sample sets rather than a difference in alignment accuracy.


By reseeding the pseudorandom number generator, ALE versions 0.4.8 and later
instead use a consistent set of pixels from the accumulated image when
comparing two transformations.  Tests sampling 3% of pixels from a set of
320x240 frames indicate that this approach improves alignment.


Sampling characteristics



For an image with 100,000 pixels and specified
s in the interval [0.005,0.995], ALE's sampling method results in
a ratio s within 0.000003 of the specified s.  This number 
improves with image size.  (The results are outlined in a table.)  However, note that s only represents an expected
value, and the actual number of sampled pixels may vary by more than the
numbers given here.


Interaction with level-of-detail



When reduced level-of-detail is used, the number of reduced-detail pixels
sampled is taken to be a percentage of the total number of pixels in the
full-detail image, rather than as a percentage of the total number of pixels in
the reduced-detail image.  (When this fraction of pixels in the full-detail
image is more than the number of reduced-detail pixels available, all
reduced-detail pixels are used.)  This may improve the likelihood of successful
alignment, but may also add overhead to the alignment process.

Error



Error calculations are used to determine whether a transformation is "good"
or not, and in particular, whether one transformation is better or worse than
another.  A smaller error indicates a better transformation, from the perspective
of the alignment algorithm.


ALE defines an error value for each pixel of the alignment reference image, and also
comprehensive error, which summarizes the error over all pixels.  


Pre-Alignment Exposure Registration



When exposure registration is enabled, ALE performs an exposure registration
step prior to alignment.  The result of this step is dependent on the initial
alignment (this can be either the default initial alignment or an alignment
loaded from a transformation data file).  See the source for more details.


Per-Pixel Error






The per-pixel error for pixel (i, j) in the alignment reference
image A, frame B, and transformation T, is:




p(i, j, A, B, T) = Abs( A(i, j) - B(T_inverse(i, j)) )metric_exponent






where Abs() is the absolute value function and B(T_inverse(i,
j)) is determined by bilinear interpolation (unless a different interpolant
is specified using --afilter).  If not specified by the --metric
option, metric_exponent defaults to 2.


For coordinates where B(T_inverse(i, j)) is not defined, the error is zero.
(Feedback from Angelo Pesce led to clarification of this point.)


In addition to per-pixel error, a per-pixel maximum error
estimator is calculated, as follows:




p_max(i, j, A, B, T) = Max( A(i, j), B(T_inverse(i, j)) )metric_exponent






For coordinates where B(T_inverse(i, j)) is not defined, the maximum error
estimator is zero.  (Feedback from Angelo Pesce led to clarification of this
point.)



Comprehensive Error



There are two varieties of comprehensive error used by ALE: exhaustive
error (enabled by --no-mc) and Monte Carlo error (enabled by --mc).
Whereas the exhaustive approach evaluates the error for each pixel in the
alignment reference image, the Monte Carlo approach evaluates
only a subset of pixels.  


If we consider Sum[] to provide the sum over whatever subset of
pixels we are sampling (including possibly the set of all pixels), then the
comprehensive error function, for alignment reference image A, frame
B, and transformation T, is:




E(A, B, T) = (Sum [ p(i, j, A, B, T) ] / Sum [ p_max(i, j, A, B, T) ])(1/metric_exponent)

ALE Rendering Chains



In cases of spatially non-uniform resolution, rendering chains can maintain low
aliasing in poorly-resolved regions while preserving detail in well-resolved
regions.  Each chain is based on a sequence of rendering invariants, each
allowing first, last, average, minimum, or maximum pixel values to be rendered.
For a given invariant, exclusion regions are honored by default, but can
optionally be ignored.  Finally, for a given invariant, resolution can be
limited to the minimum of the input and output images, to prevent aliasing, or
can use the full resolution of the output image, to prevent loss of fine
details.

Chains



A chain c is based on a sequence of rendering invariants v1, v2, ..., vmax.  For each vx, define wx:



wx(n, i, j, E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn) = ∑n'∈0..n ∑(i', j')∈Dom[dn'] vx(n, n', i, j, i', j', E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn)




If wt is the weight threshold (ALE option 'wt'), and there exists a smallest x such that:



wx(n, i, j, E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn) ≥ wt



Then c gives:



c(n, n', i, j, i', j', E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn) = vx(n, n', i, j, i', j', E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn) / wx(n, i, j, E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn)



Otherwise, c gives:



c(n, n', i, j, i', j', E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn) = vmax(n, n', i, j, i', j', E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn) / wmax(n, i, j, E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn)



If both of the expressions above are undefined, then c gives:



c(n, n', i, j, i', j', E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn) = 0





Invariants



There are five types of rendering invariants, all of which are parameterized
with a scaled sampling filter with exclusion, denoted here by the symbol e.  In particular, an
invariant can be of initial, final, maximal, minimal, or average type.  


Initial



If an invariant v is of initial type, then choose the smallest m such that
the following expression is non-zero:



∑(i',j')∈Dom[dm] e(m, i, j, i', j', Em, G, Pm, Bm, dm)



If such an m can be chosen, then, using the C trinary if-else operator to express condition:



v(n, n', i, j, i', j', E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn) = (n' == m) ? e(m, i, j, i', j', Em, G, Pm, Bm, dm) : 0



Otherwise:


 v(n, n', i, j, i', j', E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn) = 0

 


Final



If an invariant v is of final type, then choose the largest m such that
the following expression is non-zero:



∑(i',j')∈Dom[dm] e(m, i, j, i', j', Em, G, Pm, Bm, dm)



If such an m can be chosen, then, using the C trinary if-else operator to express condition:



v(n, n', i, j, i', j', E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn) = (n' == m) ? e(m, i, j, i', j', Em, G, Pm, Bm, dm) : 0



Otherwise:


 v(n, n', i, j, i', j', E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn) = 0

 


Minimal



If an invariant v is of minimal type, then choose m such that the following
expression is defined and minimal:



∑(i',j')∈Dom[dm] Em-1G-1dm(i',j') * e(m, i, j, i', j', Em, G, Pm, Bm, dm) / ∑(i',j')∈Dom[dm] e(m, i, j, i', j', Em, G, Pm, Bm, dm)



If such an m can be chosen, then, using the C trinary if-else operator to express condition:



v(n, n', i, j, i', j', E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn) = (n' == m) ? e(m, i, j, i', j', Em, G, Pm, Bm, dm) : 0



Otherwise:



v(n, n', i, j, i', j', E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn) = 0




Maximal



If an invariant v is of maximal type, then choose m such that the following
expression is defined and maximal:



∑(i',j')∈Dom[dm] Em-1G-1dm(i',j') * e(m, i, j, i', j', Em, G, Pm, Bm, dm) / ∑(i',j')∈Dom[dm] e(m, i, j, i', j', Em, G, Pm, Bm, dm)



If such an m can be chosen, then, using the C trinary if-else operator to express condition:



v(n, n', i, j, i', j', E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn) = (n' == m) ? e(m, i, j, i', j', Em, G, Pm, Bm, dm) : 0



Otherwise:



v(n, n', i, j, i', j', E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn) = 0




Average



If an invariant v is of average type, then:



v(n, n', i, j, i', j', E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn) = e(n', i, j, i', j', En', G, Pn', Bn', dn')




Scaled Sampling Filter with Exclusion (SSFE)



A scaled sampling filter with exclusion e is parameterized with a scaled sampling filter s, and
can be of two types: it can either honor exclusion regions or not.  Define
is_exclude(n', i, j) to be false if point (i, j) is not excluded
for frame n', or if exclusion regions are not being honored.  Then,
using the C trinary if-else operator to express condition:



e(n', i, j, i', j', E, G, P, B, d) = is_exclude(n', i, j) ? 0 : s(i, j, i', j', P, B, κG-1E-1d)




Where κ is the operator for certainty.


Scaled Sampling Filter (SSF)



Define bayer(i, j) to be a function that returns an RGB value whose
channels are either zero or one, depending on whether that color is sampled at
(i, j).


A scaled sampling filter s is parameterized with a sampling filter
f, and can be one of two types: fine or coarse.  If it is fine, then,
using P and B as functions:



s(i, j, i', j', P, B, k) = bayer(i', j') * k(i', j') * f(B(P(i', j')) - (i, j))




If SSF s is coarse, then color channels are handled separately,
depending on their density relative to the output image, at point (i, j)
in the output image.  In particular, bayer patterns can cause some colors to be
more dense than others.  If the local density of channel h is lower in
each dimension than the density of channel h in the output image, then:



[s(i, j, i', j', P, B, k)]h = [bayer(i', j') * k(i', j') * f((i', j') - P-1(B-1(i, j)))]h




Otherwise, if channel h is locally less dense by a factor d in
exactly one dimension of the input image, then set d_pair equal to
(1, d) or (d, 1), according to the dimension, and:



[s(i, j, i', j', P, B, k)]h = [bayer(i', j') * k(i', j') * f(d_pair * (B(P(i', j')) - (i, j)))]h




Otherwise, channel h is locally at least as dense in both dimensions of 
the input image as it is dense in the output image.  In this case:



[s(i, j, i', j', P, B, k)]h = [bayer(i', j') * k(i', j') * f(B(P(i', j')) - (i, j))]h






Sampling Filter



Sampling filters can be one of the following:

ALE Devices



Device specification is optional.  Specifying a device allows automatic
determination of point-spread functions,
refinement of the correspondence between incident light and pixel values (e.g.
power law), and refinement of certainty calculation.  


--device <d>      Set the capture device to <d>.




Available devices are as follows:





canon_300d_raw_linearCanon 300D (Digital Rebel) raw, linear data.  [0.7.2 and later]

canon_300d_raw_linear+50mm_1.4Canon 300D with EF 50mm f/1.4 lens, unspecified aperture.

canon_300d_raw_linear+50mm_1.4@1.4Canon 300D with EF 50mm f/1.4 lens, aperture 1.4.

canon_300d_raw_linear+50mm_1.8Canon 300D with EF 50mm f/1.8 lens, unspecified aperture.

canon_300d_raw_linear+85mm_1.8Canon 300D with EF 85mm f/1.8 lens, unspecified aperture.

ov7620_raw_linearOmniView OV7620 in raw RGB, linear mode.  [0.7.0-patch1 and later]

xvp610_640x480IBM PC Camera Pro (XVP610) in 640x480 mode.

xvp610_320x240IBM PC Camera Pro (XVP610) in 320x240 mode.




These device options are described in more detail below.


Canon 300D (Digital Rebel) [0.7.2 and later]



Direct support for CRW files depends on the ImageMagick configuration, and
may not be available on all platforms.  Dave Coffin's dcraw program, invoked with
arguments -d -4, will produce a raw, linear PPM file suitable for use with this
device configuration.  JPEG files produced by the 300D cannot be directly used
as inputs for this configuration, since they are gamma-corrected rather than
linear.



OV7620 [0.7.0-patch1 and later]



Standard OV7620 drivers may not include options for setting raw RGB or linear
modes.  Linux users may apply a driver patch to access
these modes.  Setting the module option rgb_raw=2 places the camera
into the desired mode.



XVP610



Users of XVP610 cameras and Linux may wish to apply a driver patch.  This version of ALE expects that this patch has been applied.

ALE 3D Modeling [Very Experimental]



When considering images captured by a camera, the projective class of 2D
transformations can compensate for arbitrary changes in position and
orientation when the scene consists of a diffuse flat surface, and arbitrary
changes in orientation (but not position) otherwise.  In order to support
changes of position and orientation in the general case, it is necessary to
construct a 3D model of the scene.  ALE currently has no reliable method for
doing this, but the scene reconstruction code included in versions 0.7.2 and
later may be a useful starting point for developing such a method.


View Angle



In versions 0.7.3 and above, the diagonal view angle of the camera can be
specified on the command line.  If no value is specified, the default value is
either device specific (if a device with a known view angle is specified), 43.7
degrees [ALE 0.7.3 and above], or 90 degrees [ALE 0.7.2].


--view-angle <x>  Set the diagonal view angle to <x> degrees.  [ALE 0.7.3 and above]




View Output [Very Experimental]


The view output option provides a reconstruction of the scene as viewed from a
particular frame's vantage point.


--3dv <n> <o>     Render file <o> from a 3D model using the <n>th frame view.  [Very Experimental]




Depth Output [Very Experimental]


The depth output option provides reconstructed depth information associated
with a view.


--3dd <n> <o>     Render 3D depth information <o> for the view from frame <n>.  [Very Experimental]

ALE Rendering Chains



The ALE incremental renderer is configured using rendering chains.  Rendering chains are
constructed hierarchically from: invariants, SSFEs (scaled sampling filters
with exclusion), SSFs (scaled sampling filters), and sampling filters.  Each of
these components is described in a section below.  Defaults are outlined in the
final section.


Chains



The chain is the top level of the rendering chain hierarchy, and is composed of a
sequence of invariants.  Syntactically, a chain is specified as a number of
invariants separated by commas:



invariant1,invariant2,invariant3,...,invariantn




Each rendered pixel is assigned a value at the first invariant whose weight
exceeds the weight threshold, or otherwise at the last invariant in the sequence.


Chain Options



--wt <w>          Set weight threshold for defined pixels    (default is 0.8).
--dchain <g>      Use chain <g> to render the default output.
--ochain <g> <o>  Use chain <g> to render output file <o>.
--achain <g>      Use chain <g> to render the alignment reference image.




Chain Examples

             fine:box:1                           Drizzling (roughly)
             fine:sinc*lanc:8                     High-frequency preservation
             last:nex:sinc*lanc:8                 Useful for video stabilization
             fine:box:1,triangle:2                Multi-resolution rendering
             fine:sinc*lanc:8,sinc*lanc:8         Multi-resolution rendering




Invariants



Invariants determine whether the rendered pixel value should be taken from a
single frame, or from an average of all frames.  If from a single frame, it can
be the first, last, minimal, or maximal pixel value.  By default, the average
is used.  The syntax is as follows:






Syntax
   
Description


avg:<SSFE>Average value

max:<SSFE>Maximum value

min:<SSFE>Minimum value

first:<SSFE>First value

last:<SSFE>Last value

<SSFE>Same as avg:<SSFE>






Scaled Sampling Filter with Exclusion (SSFE)



SSFEs qualify SSFs, indicating whether exclusion regions should be honored.






Syntax
   
Description


ex:<SSF>Honor exclusion regions

nex:<SSF>Don't honor exclusion regions

<SSF>Same as ex:<SSF>






Scaled Sampling Filter (SSF)



SSFs indicate whether filtering should occur at the resolution of the output
image, or at the minimum of input and output image resolutions.  The former prevents loss
of details; the latter prevents aliasing.






Syntax
   
Description


fine:<SF>Filter at full output image resolution

coarse:<SF>Filter at minimum resolution

<SF>Same as coarse:<SF>






SSF Options


--afilter <s>     Use SSF <s> to interpolate points in alignment.




Sampling Filter (SF)



SFs are used to limit bandwidth.  Primitive functions and pointwise multiplication of these
functions (windowing) are available.






Syntax
   
Description


sincSinc filter: (sin πx) / (πx)

lanc:<x>Lanczos, diameter x.

triangle:<x>Triangle, diameter x.

box:<x>Box, diameter x.

zeroZero function

<f>*<f>Pointwise multiplication (windowing)






Defaults



ALE defaults are as follows:



                     dchain         Varies by default setting
                     achain         Varies by default setting
                     afilter        internal (approximates triangle:2)

ALE Point Spread Functions



The ALE Irani-Peleg renderer uses a point-spread function to model the optical
and electronic properties of the capture device used.  The PSF can be specified
in terms of one linear and one non-linear component.


PSF specification



The PSF can be explicitly specified by using one or both of the psf options.


--lpsf <p>        Set linear colorspace point-spread function to <p>
--nlpsf <p>       Set non-linear colorspace point-spread function to <p>



Available explicit point-spread functions are as follows:


box=<d>           Set the PSF to a box filter with diameter <d>.
circle=<d>        Set the PSF to a circular filter with diameter <d>.  [ALE 0.7.1 and later.]
stdin             Specify a custom filter at runtime.
stdin_vg          stdin with vertically-oriented gaps after every 8th pixel.
<p>+<p>           Summation of two functions
<p>^<p>           Convolution of two functions.  [ALE 0.7.3 and later.]
<n>*<p>           Multiplication by a scalar <n>.  [ALE 0.7.3 and later.]



If a device is known to ALE, then its PSF can be implicitly set with the
--device option.  (See the device page
for more information.)  If a device is not specified, then the default linear
PSF component is box=1.  The non-linear PSF component is disabled
by default.


Determining the PSF



The PSF can be approximated based on images of known scenes.  The ALE source
distribution includes an experimental script that numerically approximates the
PSF in this way (d2/render/psf/ale-psf-calibrate).  Other, more
efficient methods for approximating the PSF are likely possible, however.

[ Up ]


ALE Rendering



Rendering determines how an output image is constructed from a series of
aligned input frames, and occurs in two stages: incremental rendering and
Irani-Peleg rendering.  Additional rendering options include exposure
registration, certainty-weighted rendering, spatial extension, range extension,
scaling, and bayer pattern specification.  Experimental options for video
stream processing are also available.


Incremental Rendering



The incremental renderer uses configurable rendering
chains to determine the output image.  It can increase resolution and
reduce aliasing, but it cannot reduce blur.


Irani-Peleg Rendering



The Irani-Peleg renderer uses configurable point-spread
functions to model blur, which is then reduced by an iterative
backprojection technique.  For iteration defaults, see the  default settings page.


--ips <i>         Run <i> iterations.




Exposure Registration



By default, ALE adjusts an exposure model to minimize differences in tone
between frames.  The option --exp-noregister indicates that
exposure should be assumed uniform across all frames.  In this case, no
adjustment is performed.



--exp-register    Register exposure between frames.  [default]
--exp-noregister  Assume uniform exposure across all frames.




Certainty-weighted Rendering



The exposure model in ALE includes an associated certainty function, which
quantifies the reliability of sensor measurements.  By default, this function
is raised to the zeroth power, to obtain uniform certainty for all measurements.
To specify a different certainty exponent, the option --cx can be
used.  This option is best used in combination with --exp-extend
(see below) and --ips.  For defaults, see the 
default settings page.


--cx <x>          Render with certainty exponent <x>
--no-cx           Render with uniform certainty.




Scale factor



Rendering with a larger scale factor results in image output of the specified
larger scale.  Larger scales can improve alignment precision and output image
quality, but can also increase alignment and rendering times.


--scale=x         Scale images by the factor x (where x is at least 1.0)




Image extents



The --extend option records pixel data that falls outside of the region of the
first frame in the sequence.  This can be useful for providing additional
alignment constraints or creating panoramic image mosaics.  (For mosaics, see
also the description of the --follow option in the alignment section.)


--extend          Increase image extents to accommodate all pixel data.
--no-extend       Don't increase extents; crop to original frame. [default]




Exposure extents



By default, ALE restricts the output range to that of the original frame.
To adjust the output range to accommodate the ranges of all input frames,
specify --exp-extend.  For defaults, see the 
default settings page.


--exp-extend      Extend range to include all calculated values.
--exp-noextend    Restrict to the original frame's range.




Bayer pattern specification



Many cameras sample only one color channel per output pixel.  To ignore the
other channels, a bayer pattern can be specified.  In versions prior to 0.7.3,
device-specific bayer patterns override the command-line specification.  In
version 0.7.3 and later, the reverse holds.


--bayer <b>       Set default bayer pattern to <b>, one of:
                    (clockwise from top left pixel)
                      rgbg      Red-green-blue-green
                      gbgr      Green-blue-green-red
                      grgb      Green-red-green-blue
                      bgrg      Blue-green-red-green
                      none      RGB-RGB-RGB-RGB
                  Default is none or device-specific.




Video stream processing (Experimental)



If a sequence of frames represents a video stream, then, in addition to
producing a single output image, ALE can also produce one or more sequences of
processed frames, corresponding to one or more occurrences of the
--visp option.  This option has its own associated scaling option,
as well as an option to show excluded regions as dimmed wherever possible.



--visp <args>     Process a video sequence.
                     <args> are:
                         <chain> <stabilization-type> <prefix> <suffix>
                     <chain> is an incremental rendering chain.
                     <stabilization-type> is one of:
                         ma:<x>     Moving average over 2*<x> + 1 frames
                         sf:<x>     Stabilize to single frame number <x>
                         identity   Same as ma:0
                     <prefix> is an output file prefix
                     <suffix> is an output file suffix
--visp-scale=<x>  Use scale <x> for VISP output.  (default is 1.0)
--exshow          For single-invariant chains, show --ex regions dimmed.




Video stream processing example



To mimic the behavior of repeated applications of the 0.6.0
--replace option over a sequence of frames, the following
--visp option could be used.


--visp last:nex:triangle:2 sf:0 frame .jpg




For better filtering, the following option could be used instead:


--visp last:nex:sinc*lanc:6 sf:0 frame .jpg

more information about these options, see the alignment and rendering
manual pages.  Details regarding these defaults are provided in the following sections.


High speed (--q0)


--q0 emphasizes speed over image quality.  This option is default, and
sets other options' defaults as follows:


   --dchain fine:box:1,triangle:2
   --achain triangle:2
   --mc 30
   --ips 0
   --exp-noextend
   --no-cx




Low noise (--qn)


--qn emphasizes low noise over resolution and rendering speed, and
sets the following defaults:


   --dchain sinc*lanc:6
   --achain sinc*lanc:6
   --mc 50
   --ips 0
   --exp-noextend
   --no-cx




Balanced quality and speed (--q1)


--q1 balances image quality and rendering speed, offering higher
resolution than --qn.  It sets the following defaults:


   --dchain fine:sinc*lanc:6,sinc*lanc:6
   --achain sinc*lanc:6
   --mc 50
   --ips 0
   --exp-noextend

--q2 favors image quality over rendering speed, offering greater
emphasis for high-frequency details than --q0, --qn,
or --q1.  It depends on the --lpsf and
--nlpsf options, which can be set indirectly via the
--device option.  (More information about these options can be
found on the PSF and device pages.)  --q2
sets the following defaults:


   --dchain sinc*lanc:8
   --achain sinc*lanc:8
   --no-mc
   --ips 4
   --exp-noextend
   --no-cx




Range extension (--qr)



--qr is similar to --q2, but offers improved
rendering when input images have been taken with unequal exposures.  In other
cases, it might exacerbate noise in light and dark regions, and so should not
be used.  This option sets the following defaults:


   --dchain sinc*lanc:8
   --achain sinc*lanc:8
   --no-mc
   --ips 6
   --exp-extend
   --cx 0.7

ALE Exclusion Regions



ALE offers exclusion regions as a way to disallow certain areas from being
used in alignment and (optionally) rendering.  Spatial coordinates are
expressed in the rendering coordinate system (prior to scaling).  In cases
where the default transformation is used with the original frame, this is
identical to the unscaled original frame coordinate system, taking the
upper-left corner to be (0, 0).  Frame numbering begins with 0, which represents
the original frame.


All specified volumes are excluded from alignment (except where they affect
the alignment reference image), and are excluded from rendering by default.
(See the rendering chains page for
information on how to ignore exclusion regions.)  Exclusion region syntax is
as follows:


--ex <args>       Exclude a specified volume.
                     <args> are space-delimited horizontal,
                     vertical, and frame limits:
                         <xmin> <xmax> <ymin> <ymax> <fmin> <fmax>

Alignment



Alignment compares each supplemental frame in the sequence with an intermediate
incremental rendering known as the alignment reference image.  Based on this
comparison, a transformation is assigned to the supplemental frame.  Many
different transformations can be assigned before alignment of the frame is
complete.


This manual page offers an overview of alignment options; linked from this
page is a sub-page offering more detail on transformation
data files.


Transformations



The variables used to adjust alignment are called transformations; they map
points from the source image coordinate system to a target coordinate system
(the rendering coordinate system).


ALE supports three transformation classes -- translational, euclidean, and
projective -- as well as barrel/pincushion distortion correction.  The
translational class applies only translations to the inputs, changing only the
positions of images; the Euclidean class applies translations and rotations;
and the projective class applies general projective transformations.
Additionally, barrel/pincushion distortion correction can be applied to each
frame.  The Euclidean class is most appropriate for use with scanners, or as a
first pass for projective transformations.  The projective class and
barrel/pincushion distortion correction are most appropriate for use with
cameras.  Except when capturing flat scenes, ALE does not correct perspective
changes, so movement of cameras should ideally be constrained so that no large
translations occur.


Transformation Class Options



--translation     Only adjust the position of images
--euclidean       Adjust the position and orientation of images [default]
--projective      Use projective transformations.  Best quality, but slow.



For more information on barrel distortion correction, see the sub-page on 
transformation data files.


Transformation data file options



Transformations used in alignment can be loaded from, or saved to, a transformation data file.  This can be useful when performing
alignment in several passes, or when refining rendering options.  A
transformation data file is required for barrel/pincushion distortion
correction.


--trans-load=x    Load initial transformation settings from file x
--trans-save=x    Save final transformation data in file x




Alignment following



The --follow option hints that frames tend to be more closely aligned with
adjacent frames in the sequence than with the original frame.  This hint can be
useful even when initial alignment information is loaded from a file.


--identity        Frames align closely with the original frame.  [default]
--follow          Frames align closely with their immediate predecessor.




Match statistics



The match statistic indicates how well a transformed frame aligns with the
alignment reference image; it is used to select or reject transformations
during alignment.  After alignment of a particular frame is complete, ALE
displays the corresponding final match statistic.  If the value is close to
100%, then the frames are well aligned; very low values can indicate
misalignment; but even frames that are very well aligned typically do not
achieve 100% alignment.  For improving image quality, ALE works most
effectively when match values are lower than 100%.


Match threshold



A match threshold can be specified; no images with final match statistics
falling below this threshold will contribute to the final output.


--threshold=x     Min. match threshold; a perfect match is 100.  (0 is default)




Alignment failure



When an image fails to meet the match threshold, a transformation is still
assigned to the frame (e.g., for writing to a transformation
data file).  The assigned transformation can be either the optimal
alignment found (this is default) or the default transformation.


--fail-optimal    Frames beneath threshold are aligned optimally.  [default]
--fail-default    Frames beneath threshold keep their default alignment.




Alignment error metric exponent



The function calculated at each pixel to determine the match statistic is called
the alignment error metric, and is of the form (a-b)x.
The value x is called the error metric exponent, and is 2 by default.
Larger numbers indicate that alignment will be more influenced by smaller
image features.


--metric=x        Set the alignment error metric exponent.       (2 is default)




Alignment Channel Options



In calculating the per-pixel error metric, there are three ways in which ALE
can handle color channels.  By default, ALE adds the channels before
calculating the match, but it can also be configured to rely solely on the
green color channel, or to use all three channels separately.


--align-all       Align images using all color channels
--align-green     Align images using the green channel
--align-sum       Align images using a sum of channels [default]




Monte Carlo Alignment



Aligning large images can take a very long time if all pixels are examined in
determining the match statistic, so it is often desirable to examine a smaller
subset of pixels.  The Monte Carlo alignment option allows this.  The number of
pixels used is specified as a percentage, and smaller numbers usually mean
faster, but less precise, alignment.  For defaults, see the 
default settings page.


--mc <x>          Align using, on average, x% of available pixels (0 < x < 100)
--no-mc           Align using all pixels.




Alignment weight map



Typically, measured differences at each pixel in the alignment reference
image contribute equally to the match statistic.  To weight pixels differently,
a weight map can be used.  The scale of the map should correspond with that of
the alignment reference image, and if the upper-left corner of the map does not
coincide with the upper-left corner of the first frame in the sequence, then a
non-zero offset should be specified to indicate the difference.  See also exclusion regions.


--wm <f> <x> <y>  Use weight map image <f> at offset (<x>, <y>)




Frequency weighting



If ALE is compiled with FFTW support, then a high-pass-filtered version of
the alignment reference image can be used to weight reference image pixels'
contributions to the match statistic.  Frequency limiting can occur as a
fraction of the highest horizontal frequency, the highest vertical frequency,
or the highest average frequency.  Limit values should range between 0 (pass
all) and 1 (pass none).  If any limit is assigned a value of 1, no alignment
will occur, since all frequencies will have been excluded.  An output file can
optionally be specified for high-pass filtered data.



--fl <h> <v> <a>  High-pass filters: horizontal <h>, vertical <v>, average <a>.
--flshow <o>      Write high-pass filtered data to file <o>.




Algorithmic weighting



This option writes the current alignment reference image and definition map
to specified files, executes a specified program with these arguments, and then
reads back alignment weights.  This option requires POSIX libraries, and
requires that ALE have been built with POSIX support enabled.



--wmx <e> <r> <d> Write reference <r>, definition <d>, execute `<e> <f> <d>`,
                  read weights <r> back.




Perturbation



The perturbation size determines the magnitude by which alignment parameters
are changed.  The size is initially set to be large, allowing large changes in
alignment to be evaluated, and is reduced as the locally optimal alignment is
found for each size.  When this size drops below a specified lower bound, the
frame is considered to be aligned.


Perturbation bounds



These options determine the upper and lower bounds for perturbation size.  The
perturb-upper and perturb-lower bounds apply to rotation (in degrees),
translation (in pixels), and the movement of the boundaries of a projected
frame (in pixels).  By appending the '%' character, values may optionally be
specified as a percentage of the number of pixels in the smallest image
dimension (0.7.1-patch1 and later).  The rot-upper bound disables rotational
perturbation above a certain perturbation size (in degrees).  To disable
alignment, set perturb-upper to zero.


--perturb-upper=x Perturbation upper bound in pixels/degrees   (14% is default)   [0.7.1, and earlier, default to 32.0]
                     ('x%' uses a fraction of the smallest image dimension.)      [0.7.1-patch1 and later]
--perturb-lower=x Perturbation lower bound in pixels/degrees  (.125 is default)
                     ('x%' uses a fraction of the smallest image dimension.)      [0.7.1-patch1 and later]
--rot-upper=x     Rotation-specific perturbation upper bound  (32.0 is default)




Barrel/pincushion distortion adjustment multiplier and rate



When using barrel/pincushion distortion parameters, any frame-to-frame
adjustments to these parameters are made in a manner dependent on the
perturbation size.  A multiplier, the barrel distortion adjustment multiplier,
is used to determine the perturbation of these parameters, based on the generic
perturbation size.  Additionally, the frame-to-frame rate of change of each
barrel distortion parameter can be limited to a specified maximum.  To disable
frame-to-frame adjustment of barrel/pincushion distortion parameters, set
bda-mult to zero.  Setting bda-rate to zero disables rate limitation.


--bda-mult=x      Barrel distortion adjustment multiplier   (0.0001 is default)
--bda-rate=x      Barrel distortion rate of change maximum  (0.0004 is default)




Level of detail



Alignment at large perturbation sizes is usually carried out on
reduced-detail images.  To disable this, set lod-max to
log2(perturb-upper).


--lod-max=x       LOD scale factor is max(1, (2^floor(x))/perturb)  (1 is def.)




Perturbation Types (experimental; 0.7.1-patch1 and later)



Perturbations are normally performed in output image coordinates.  To perform
perturbations in source image coordinates, specify --perturb-source.


--perturb-output  Apply perturbations in output image coordinates. [default]  [0.7.1-patch1 and later]
--perturb-source  Apply perturbations in source image coordinates.            [0.7.1-patch1 and later]




Global Searching (experimental; 0.7.0-patch1 and later)



In cases where important image features do not have sufficient overlap using
default alignment parameters (determined by --identity and
--follow), a number of translations can be applied to the default
parameters in order to find a new alignment starting point.  Since this process
searches the entire region of the alignment reference image, it is called a
global (as opposed to local) search.  To avoid misalignment, a minimum overlap
area can be specified [0.7.1-patch2 and later].


--gs <type>       Set global search to <type>, one of:                             [0.7.0-patch1 and later]
                     local     Local alignment only [default]
                     inner     Alignment reference image inner region
                     outer     Alignment reference image outer region
                     all       Union of inner and outer
                     central   inner if below threshold or better; else, outer.

--gs-mo <x>       Set <x> pixel min. overlap for global search. (16 is default)    [0.7.1-patch2 and later]

ALE Transformation Data Files


Transformation data files are useful when performing alignment in several
passes or refining rendering options, and are necessary for specifying
barrel/pincushion distortion parameters.  They also offer a way to manually
specify alignment when ALE cannot automatically align images.  


Multiple-pass alignment


To align images in multiple passes, load the saved results of each previous
pass, as follows:


$ ale --trans-save=a.t <first pass arguments>
$ ale --trans-load=a.t --trans-save=b.t <second pass arguments>
$ ale --trans-load=b.t --trans-save=c.t <third pass arguments>
.
.
.




Rendering option refinement


To refine rendering options using the same alignment, first save the alignment
for the first option set, and then load the saved alignment information with
each subsequent option set, setting the perturbation upper bound to zero to
prevent a new alignment pass from occurring:


$ ale --trans-save=a.t <first option set>
$ ale --trans-load=a.t --perturb-upper=0 <second option set>
$ ale --trans-load=a.t --perturb-upper=0 <third option set>
.
.
.




Alignment file syntax (version 2)


There are two varieties of alignment file syntax that are both read and written
by ALE 0.7.0.  The most basic of these is version 2.  Version 3 is slightly
more complex, and is covered in the next section.

At the highest level, version 2 transformation data files contain the following
components: (a) a version command, and (b) a sequence of transformation
commands, one for each supplemental frame.  Each line of text should contain at
most one command, between which optional comments may be interspersed.  A
transformation command can be Euclidean, projective, or default.  Euclidean and
projective commands take several arguments, including the width and height of
the supplemental frame.  Default commands take no arguments.  Commands are
outlined in more detail below.


Version command



The version 2 version command is as follows:



V 2




Euclidean commands



The structure of a Euclidean command is as follows:



E <image width> <image height> <x-offset> <y-offset> <rotation-angle>




Projective commands



Projective commands map the four corners of the supplemental frame to four
points in the rendering coordinate system:



P <image width> <image height> <top-left-x> <top-left-y> <blx> <bly> <brx> <bry> <trx> <try>




Default commands


Default commands can be explicitly written as follows:


D



Alternatively, if there are more frames than alignment commands (euclidean,
projective, or default), then the last supplemental frames in the frame
sequence will be assigned the default command.


Comments


Comments can be inserted with the following syntax:


# This comment extends to the end of this line.  I can write anything I want here.




Alignment file syntax (version 3)


Version 3 syntax is required for specifying transformations for the original
frame, and for specifying barrel/pincushion distortion parameters.  


In version 3, the first transformation command is associated with the
original frame, instead of being associated with the first supplemental frame.
Also, barrel/pincushion distortion commands can precede each projective,
Euclidean, or default command.


Version command



The version 3 version command is as follows:



V 3




Barrel/pincushion distortion command


In version 3, barrel/pincushion distortion commands are supported.  Distortion
is modeled as a transformation affecting the distance of image features from the
image center.  The distorted distance is expressed as a polynomial function of
the undistorted distance.  Zeroth and first order coefficients are fixed or
automatically determined; additional coefficients can be specified explicitly,
using the following syntax:


B <n> <coefficient 2> <coefficient 3> ... <coefficient n+1>




Barrel/pincushion distortion commands should precede the projective, Euclidean,
or default transformation command for the corresponding frame.

ALE File Output



File output options determine the format in which rendered images are written,
and how frequently they are written.  Depending on the compilation options used,
available file output options vary.


Output Color Depth



Output color depth of 8 or 16 bits of precision per color channel can be specified,
for 24-bit or 48-bit color, respectively.  


--8bpc            Write 8 bit per channel output [default]
--16bpc           Write 16 bit per channel output




Extension-based file type determination



If ALE has been built with ImageMagick support, then the output file type can
be determined automatically by file extension.  This is the default behavior
for ImageMagick builds.  The --auto flag explicitly specifies that
the default behavior should be used; it generates an error on builds compiled
without ImageMagick support.  


--auto            Determine file type automatically




PPM Output



All builds of ALE support PPM output.  PPM can be written in plain (ASCII) or
raw (binary) format.  If ALE has been built without ImageMagick support, or if
the file type cannot be automatically determined by file extension, then raw
PPM output is used by default.


--raw             Write raw PPM output
--plain           Write plain PPM output




Incremental Output



By default, ALE writes intermediate results periodically throughout the rendering
process.  This behavior can be disabled, however, so that output is written only
after rendering is complete.


--inc             Produce incremental output.  [default]
--no-inc          Don't produce incremental output.

Device specification is optional.  Specifying a device allows automatic
determination of point-spread functions,
refinement of the correspondence between incident light and pixel values (e.g.
power law), and refinement of certainty calculation.

These device options are described in more detail below.


Canon 300D (Digital Rebel)



Direct support for CRW files depends on the ImageMagick configuration, and
may not be available on all platforms.  Dave Coffin's dcraw program, invoked with
arguments -d -4, will produce a raw, linear PPM file suitable for use with this
device configuration.  JPEG files produced by the 300D cannot be directly used
as inputs for this configuration, since they are gamma-corrected rather than
linear.



OV7620



Standard OV7620 drivers may not include options for setting raw RGB or linear
modes.  Linux users may apply a driver patch to access
these modes.  Setting the module option rgb_raw=2 places the camera
into the desired mode.



XVP610



Users of XVP610 cameras and Linux may wish to apply a driver patch.  This version of ALE expects that this patch has been applied.

ALE 3D Scene Reconstruction



In general, 3D modeling of scenes may allow handling of cases that per-frame
projective transformations do not allow, such as registering frames having
different viewpoints over a non-flat or specular scene, or recovery of depth
from frames having different viewpoints.  ALE's implementation of 3D scene
reconstruction is considered experimental in versions prior to 0.8.3.


Models



The method of modeling used in 0.8.2 and later is spatial subdivision based on
regions of interest, followed by iterative update of the estimated occupancy
and color of each region of interest.  (For a general discussion of occupancy,
see Hans Moravec's work on depth recovery.)  In 0.8.1, the method of modeling
is decomposition and deformation of a surface.  In earlier versions, a
per-frame, per-pixel model of depth is used.


Recovered Color and Depth Output



The color and depth output options provide a reconstruction of the scene as
viewed from a particular frame's vantage point, or from an arbitrary camera
view [0.8.2 and later].  In 0.8.2 and later, normalization of output values by
accumulated occupancy can optionally be disabled for unfiltered views.  Version
0.8.3 adds support for options --et and --3dpx, which can be useful for 3D
cropping applications.  --et specifies the minimum accumulated weight required
for a pixel to be defined, allowing refinements of crops based on clip planes
(--rc and --fc) established prior to scene
reconstruction, whereas --3dpx specifies a region of space to be removed 
after scene reconstruction.  0.8.3 uses depth image pixels to determine such spatial regions,
leaving the pixels undefined, whereas 0.8.4 removes scene geometry prior to
rendering, allowing rendering of background objects after the foreground has been removed.

                         <xmin> <xmax> <ymin> <ymax> <zmin> <zmax>




Filtering [0.8.4 and later]


Version 0.8.4 adds support for filtering color values from the inputs to
produce final color renderings.  This is now the default.  Determining surface
depth and gradient for filtering the inputs draws from a set of depth pixels
within a disc whose radius can be specified with the --3d-dmr and --3d-fmr
options.

Filtering color from views distributed on a disc (about the camera origin) of
specified aperture allows simulation of focus effects; such effects can be
controlled with the --focus option.


--3d-filter       Use filtering for 3D color output.                    [default]
--3d-nofilter     Don't use filtering for 3D color output.
--3d-dmr <x>      Set radius for filtering median depth to <x>        [default 0]
--3d-fmr <x>      Set radius for filtering median diff to <x>         [default 0]
--focus <ft> <op> Create focus region with type <ft> and options <op>:
                     Focus type:
                        d <d>           focus at distance <d>
                        p <x> <y>       focus at point (x, y)
                     Space-separated options may include zero or more of:

                        sr=<sr>  view sample randomization:
                            aperture  per aperture            [default]

                            median    median of views





Camera parameter adjustment



In versions 0.8.1 and later, camera parameters can be adjusted according to
control points to decrease the error between points in different frames.
Perturbation bounds for adjustment can be specified, including an additional
upper bound on view angle perturbation, and a stereo threshold can be set for
discarding control points after adjustment is complete.  An initial camera view
angle can also be specified.  Versions 0.8.2 and later allow calculation of
error by median rather than mean, and also allow disabling of adjustment of
orientation and/or position.


--view-angle <x>  Set the initial diagonal view angle to <x> degrees.
                     (Default is 43.7 degrees or device-specific.)
--cpp-upper=<x>   Set upper bound <x> for camera parameter perturbation,           [0.8.1 and later]
                  in pixels or degrees [default is 32]                            
--cpp-lower=<x>   Set lower bound <x> for camera parameter perturbation,           [0.8.1 and later]
                  in pixels or degrees [default is 0.125]                    
--va-upper=<x>    View-angle perturbation upper bound in degrees  [default is 32]  [0.8.1 and later]
--st <x>          Control point stereo threshold is <x> pixels.    [default is 4]  [0.8.1 and later]
--cpp-err-mean    Use RMS error to determine camera parameters.         [default]        [0.8.2 and later]
--cpp-err-median  Use median error to determine camera parameters.                       [0.8.2 and later]
--vp-adjust       Adjust the view point                                 [default]        [0.8.2 and later]
--vp-noadjust     Do not adjust the view point                                           [0.8.2 and later]
--vo-adjust       Adjust the view orientation                           [default]        [0.8.2 and later]
--vo-noadjust     Do not adjust the view orientation                                     [0.8.2 and later]




Transformation data files [0.8.2 and later]


Transformation data file options allow reading and writing of camera position,
orientation, and view angle information.


--3d-trans-load=x Load initial transformation settings from file x                       [0.8.2 and later]
--3d-trans-save=x Save final transformation data in file x                               [0.8.2 and later]




Transformation data file format [0.8.2 and later]



The transformation data file uses the following format, starting with a version
command, and then describing view angle and euclidean transformation of each
frame in turn:


W 0
V <view angle>
E <width> <height> <X> <Y> <Z> <P> <Y> <R>
V <view angle>
E <width> <height> <X> <Y> <Z> <P> <Y> <R>
.
.
.
V <view angle>
E <width> <height> <X> <Y> <Z> <P> <Y> <R>




Model costs [0.8.1 only]



After the cameras are adjusted, a 2D surface is decomposed and deformed to
reduce local cost measures, calculated from angles between neighboring
triangles, edge lengths, and differences in color between different views.
Multipliers for edge length and angle costs can be specified on the
command line.



--ecm <x>         Set edge length cost multiplier <x>.         [default is 0.001]  [0.8.1 only]
--acm <x>         Set angle cost multiplier <x>.               [default is 0.001]  [0.8.1 only]




Model rules [0.8.2 and later]



In versions 0.8.2 and later, clip planes can be specified, and a color falloff
exponent for pairwise occupancy estimation can be specified.  Larger exponents
are more forgiving of color differences between pixels in different frames.
In versions 0.8.3 and later, error contributions from cameras outside of the
generating pair can be assigned non-zero multipliers (--tcem), the
number of occupancy and color update iterations can be specified
(--oui), the number of points in space generated for each pixel
pair can be specified (--pa), and the type of frame pairings can
be specified (--pc).


--di-upper <x>    Decimate primary input resolution by at most 2^x [default is 0]  [0.8.4 and later]
--di-lower <x>    Decimate input resolutions by at least 2^x       [default is 0]  [0.8.4 and later]

--no-oc           Do not clip scene to output regions.                  [default]  [0.8.4 and later]
--fc <x>          Set front-clip to <x> (0 < x < 1)                [default is 0]  [0.8.2 and later]

--tcem <x>        Set third-camera error multiplier to <x>         [default is 0]  [0.8.3 and later]
--oui <x>         Set occupancy update iterations to <x>          [default is 10]  [0.8.3 and later]
--pa <x>          Set pairwise ambiguity to <x>                    [default is 3]  [0.8.3 and later]
--pc <type>       Set the type of pairwise comparisons:                            [0.8.3 and later]
                     auto     Determine comparisons automatically.      [default]
                     all      Perform all comparisons.

settings, file output, alignment, rendering, exclusion regions, control points, user interfaces, devices, and 3D scene reconstruction.


For more information on ALE, see the ALE Home Page.


Parameter Meta-syntax






 <foo>
A required parameter called foo.




[<foo>]
An optional parameter called foo.




[<foo>]*
Zero or more parameters foo.






Command-line syntax for Image Processing



The following command-line invocation can be used to process a series of
frames into an output file:


ale [<option>]* <original-frame> [<supplemental-frame>]* <output-file>



Option Arguments



Certain basic modes of operation, emphasizing image quality, speed, or other
rendering characteristics, are now established in the form of default settings.


Other options are outlined in the manual pages describing file output, rendering, alignment, exclusion
regions, devices, user interfaces,
and 3D scene reconstruction.


Image Files



ALE can be configured at compile time to use one of two different file
handlers.  Execute 'ale --version' to determine which file handler is being
used.  The table below outlines the supported formats for each file handler.









Version MessageFile Types Supported




File handler:     ImageMagick

  ALE User Manual: Rendering Chains











ALE


Image Processing Software




Deblurring, Anti-aliasing, and Superresolution.




Local Operation

[ Up ]


ALE Rendering Chains



The ALE incremental renderer is configured using rendering chains.  Rendering chains are
constructed hierarchically from: invariants, SSFEs (scaled sampling filters
with exclusion), SSFs (scaled sampling filters), and sampling filters.  Each of
these components is described in a section below.  Defaults are outlined in the
final section.


Chains



The chain is the top level of the rendering chain hierarchy, and is composed of a
sequence of invariants.  Syntactically, a chain is specified as a number of
invariants separated by commas:



invariant1,invariant2,invariant3,...,invariantn




Each rendered pixel is assigned a value at the first invariant whose weight
exceeds the weight threshold, or otherwise at the last invariant in the sequence.


Chain Options



--wt <w>          Set weight threshold for defined pixels [default is 0.8 in v0.8.0; 0.1 in v0.8.1 and later]
--dchain <g>      Use chain <g> to render the default output.
--ochain <g> <o>  Use chain <g> to render output file <o>.
--achain <g>      Use chain <g> to render the alignment reference image.
--3d-chain <g>    Use chain  by default to render 3d output.  [0.8.4 and later]





Chain Examples



             triangle:2                           ALE 0.6.0 merging (roughly)
             fine:box:1                           Drizzling (roughly)
             fine:sinc*lanc:8                     High-frequency preservation
             last:nex:sinc*lanc:8                 Useful for video stabilization
             fine:box:1,triangle:2                Multi-resolution rendering
             fine:sinc*lanc:8,sinc*lanc:8         Multi-resolution rendering




Invariants



Invariants determine whether the rendered pixel value should be taken from a
single frame, or from an average of all frames.  If from a single frame, it can
be the first, last, minimal, or maximal pixel value.  Averages include mean
and, in versions 0.8.1 and later, the median.  By default, the mean is used.
(Note that using the median value may require allocation of a quantity of
memory linear in the number of frames.)  The syntax is as follows:






Syntax
   
Description


avg:<SSFE>Mean value

median:<SSFE>Median value  [0.8.1 and later]

max:<SSFE>Maximum value

min:<SSFE>Minimum value

first:<SSFE>First value

last:<SSFE>Last value

<SSFE>Same as avg:<SSFE>






Scaled Sampling Filter with Exclusion (SSFE)



SSFEs qualify SSFs, indicating whether exclusion regions should be honored.






Syntax
   
Description


ex:<SSF>Honor exclusion regions

nex:<SSF>Don't honor exclusion regions

<SSF>Same as ex:<SSF>






Scaled Sampling Filter (SSF)



SSFs indicate whether filtering should occur at the resolution of the output
image, or at the minimum of input and output image resolutions.  The former prevents loss
of details; the latter prevents aliasing.






Syntax
   
Description


fine:<SF>Filter at full output image resolution

coarse:<SF>Filter at minimum resolution

<SF>Same as coarse:<SF>






SSF Options


--afilter <s>     Use SSF <s> to interpolate points in alignment.




Sampling Filter (SF)



SFs are used to limit bandwidth.  Primitive functions and pointwise multiplication of these
functions (windowing) are available.






Syntax
   
Description


sincSinc filter: (sin πx) / (πx)

lanc:<x>Lanczos, diameter x.

triangle:<x>Triangle, diameter x.

box:<x>Box, diameter x.

zeroZero function

<f>*<f>Pointwise multiplication (windowing)






Defaults



ALE defaults are as follows:



                     dchain         Varies by default setting
                     achain         Varies by default setting
                     afilter        internal (approximates triangle:2)

ALE Point Spread Functions



The ALE Irani-Peleg renderer uses a point-spread function to model the optical
and electronic properties of the capture device used.  The PSF can be specified
in terms of one linear and one non-linear component.


PSF specification



The PSF can be explicitly specified by using one or both of the psf options.


--lpsf <p>        Set linear colorspace point-spread function to <p>
--nlpsf <p>       Set non-linear colorspace point-spread function to <p>



Available explicit point-spread functions are as follows:


box=<d>           Set the PSF to a box filter with diameter <d>.
circle=<d>        Set the PSF to a circular filter with diameter <d>.
stdin             Specify a custom filter at runtime.
stdin_vg          stdin with vertically-oriented gaps after every 8th pixel.
<p>+<p>           Summation of two functions

If a device is known to ALE, then its PSF can be implicitly set with the
--device option.  (See the device page
for more information.)  If a device is not specified, then the default linear
PSF component is box=1.  The non-linear PSF component is disabled
by default.


Determining the PSF



The PSF can be approximated based on images of known scenes.  The ALE source
distribution includes an experimental script that numerically approximates the
PSF in this way (d2/render/psf/ale-psf-calibrate).  Other, more
efficient methods for approximating the PSF are likely possible, however.

ALE Rendering



Rendering determines how an output image is constructed from a series of
aligned input frames, and occurs in two stages: incremental rendering and
Irani-Peleg rendering.  Additional rendering options include exposure
registration, certainty-weighted rendering, spatial extension, range extension,
scaling, and bayer pattern specification.  Experimental options for video
stream processing are also available.


Incremental Rendering



The incremental renderer uses configurable rendering
chains to determine the output image.  It can increase resolution and
reduce aliasing, but it cannot reduce blur.


Irani-Peleg Rendering



The Irani-Peleg renderer uses configurable point-spread
functions to model blur, which is then reduced by an iterative
backprojection technique.  (For iteration defaults, see the  default settings page.)  In versions 0.8.1 and
later, using the median correction value can be specified.  By default,
the mean correction value is used.


--ips <i>         Run <i> iterations.
--ip-mean         Use the mean correction [default]   [0.8.1 and later]
--ip-median       Use the median correction           [0.8.1 and later]




Exposure Registration



By default, ALE adjusts an exposure model to minimize differences in tone
between frames.  The option --exp-noregister indicates that
exposure should be assumed uniform across all frames.  In this case, no
adjustment is performed.  The option --exp-meta-only indicates
that only exposure information included in the image files should be used for
registration.  Currently, EPPM is the only type of exposure
metadata supported by this option.



--exp-register    Register exposure between frames.  [default]
--exp-noregister  Assume uniform exposure across all frames.
--exp-meta-only   Use only image metadata for registering exposure.




Color Adjustment [0.8.1 and later]



To adjust the color of the output image (e.g., for white balance) in
versions 0.8.1 and later, the --exp-mult= option can be used.



--exp-mult=c,r,b   Adjust all channels by <c>, red by <r>, and blue by <b>.  [0.8.1 and later]




Certainty-weighted Rendering



The exposure model in ALE includes an associated certainty function, which
quantifies the reliability of sensor measurements.  By default, this function
is raised to the zeroth power, to obtain uniform certainty for all measurements.
To specify a different certainty exponent, the option --cx can be
used.  This option is best used in combination with --exp-extend
(see below) and --ips.  For defaults, see the 
default settings page.


--cx <x>          Render with certainty exponent <x>
--no-cx           Render with uniform certainty.




Scale factor



Rendering with a larger scale factor results in image output of the specified
larger scale.  Larger scales can improve alignment precision and output image
quality, but can also increase alignment and rendering times.


--scale=x         Scale images by the factor x, where x > 0.     (1 is default)




Image extents



The --extend option records pixel data that falls outside of the region of the
first frame in the sequence.  This can be useful for providing additional
alignment constraints or creating panoramic image mosaics.  (For mosaics, see
also the description of the --follow option in the alignment section.)


--extend          Increase image extents to accommodate all pixel data.
--no-extend       Don't increase extents; crop to original frame. [default]




Exposure extents



By default, ALE restricts the output range to that of the original frame.
To adjust the output range to accommodate the ranges of all input frames,
specify --exp-extend.  For defaults, see the 
default settings page.


--exp-extend      Extend range to include all calculated values.
--exp-noextend    Restrict to the original frame's range.




Bayer pattern specification



Many cameras sample only one color channel per output pixel.  To ignore the
other channels, a bayer pattern can be specified.


--bayer <b>       Set the bayer pattern to <b>, one of:
                    (clockwise from top left pixel)
                      rgbg      Red-green-blue-green
                      gbgr      Green-blue-green-red
                      grgb      Green-red-green-blue
                      bgrg      Blue-green-red-green
                      none      RGB-RGB-RGB-RGB
                  Default is none or device-specific.




Video stream processing (Experimental)



If a sequence of frames represents a video stream, then, in addition to
producing a single output image, ALE can also produce one or more sequences of
processed frames, corresponding to one or more occurrences of the
--visp option.  This option has its own associated scaling option,
as well as an option to show excluded regions as dimmed wherever possible.



--visp <args>     Process a video sequence.
                     <args> are:
                         <chain> <stabilization-type> <prefix> <suffix>
                     <chain> is an incremental rendering chain.
                     <stabilization-type> is one of:
                         ma:<x>     Moving average over 2*<x> + 1 frames
                         sf:<x>     Stabilize to single frame number <x>
                         identity   Same as ma:0
                     <prefix> is an output file prefix
                     <suffix> is an output file suffix
--visp-scale=<x>  Use scale <x> for VISP output.  (default is 1.0)
--exshow          For single-invariant chains, show --ex regions dimmed.




Video stream processing example



To mimic the behavior of repeated applications of the 0.6.0
--replace option over a sequence of frames, the following
--visp option could be used.


--visp last:nex:triangle:2 sf:0 frame .jpg




For better filtering, the following option could be used instead:


--visp last:nex:sinc*lanc:6 sf:0 frame .jpg

ALE currently supports two user interface types.  The traditional interface
is the stream interface, which produces only printing characters and
whitespace.  If ALE is compiled with IOCTL support, additional information can
be provided through the tty interface, which is default.

ALE Default Settings



ALE offers five different default settings, each of which emphasizes
image quality, speed, or some other rendering characteristic, as follows:



--q0              Low quality, high speed. [default]
--qn              Low noise, moderate speed.
--q1              Moderate quality and speed.
--q2              High quality, low speed.
--qr              Range-extended high quality.




These settings specify defaults for other options: --dchain, --achain,
--mc, --ips, --exp-extend, and --cx.  For
more information about these options, see the alignment and rendering
manual pages.  Details regarding these defaults are provided in the following sections.


High speed (--q0)


--q0 emphasizes speed over image quality.  This option is default, and
sets other options' defaults as follows:


   --dchain fine:box:1,triangle:2
   --achain triangle:2
   --mc 30
   --ips 0
   --exp-noextend
   --no-cx




Low noise (--qn)


--qn emphasizes low noise over resolution and rendering speed, and
sets the following defaults:


   --dchain sinc*lanc:6
   --achain sinc*lanc:6
   --mc 50
   --ips 0
   --exp-noextend
   --no-cx




Balanced quality and speed (--q1)


--q1 balances image quality and rendering speed, offering higher
resolution than --qn.  In versions 0.8.1 and later, this option
uses median values, which can be very memory-intensive to calculate.  The
following defaults are used in versions 0.8.1 and later:


   --dchain median:fine:sinc*lanc:8,triangle:2  [0.8.1 and later]
   --achain triangle:2                          [0.8.1 and later]
   --mc 50
   --ips 0
   --exp-noextend
   --no-cx



In 0.8.0, the following defaults are used:


   --dchain fine:sinc*lanc:6,sinc*lanc:6        [0.8.0]
   --achain sinc*lanc:6                         [0.8.0]
   --mc 50
   --ips 0
   --exp-noextend
   --no-cx




High quality (--q2)



--q2 favors image quality over rendering speed, offering greater
emphasis for high-frequency details than --q0, --qn,
or --q1.  It depends on the --lpsf and
--nlpsf options, which can be set indirectly via the
--device option.  (More information about these options can be
found on the PSF and device pages.)  --q2
sets the following defaults:


   --dchain sinc*lanc:8
   --achain sinc*lanc:8
   --no-mc
   --ips 4
   --exp-noextend
   --no-cx




Range extension (--qr)



--qr is similar to --q2, but offers improved
rendering when input images have been taken with unequal exposures.  In other
cases, it might exacerbate noise in light and dark regions, and so should not
be used.  This option sets the following defaults:


   --dchain sinc*lanc:8
   --achain sinc*lanc:8
   --no-mc
   --ips 6
   --exp-extend
   --cx 0.7

ALE Exclusion Regions



ALE offers exclusion regions as a way to disallow certain areas from being
used in alignment and (optionally) rendering.  Spatial coordinates are
expressed in the rendering coordinate system (prior to scaling).  In cases
where the default transformation is used with the original frame, this is
identical to the unscaled original frame coordinate system, taking the
upper-left corner to be (0, 0).  Frame numbering begins with 0, which represents
the original frame.


Rectangular Exclusion



All specified volumes are excluded from alignment (except where they affect
the alignment reference image), and are excluded from rendering by default.
(See the rendering chains page for
information on how to ignore exclusion regions.)  Exclusion region syntax is
as follows:


--ex <args>       Exclude a specified volume.
                     <args> are space-delimited horizontal,
                     vertical, and frame limits:
                         <xmin> <xmax> <ymin> <ymax> <fmin> <fmax>




Cropping


Cropping excludes the spatial complement of an area over a specified set of
frames.


--crop <args>     Exclude the spatial complement of an area over a
                  specified set of frames.  <args> are:
                         <xmin> <xmax> <ymin> <ymax> <fmin> <fmax>

Alignment



Alignment compares each supplemental frame in the sequence with an intermediate
incremental rendering known as the alignment reference image.  Based on this
comparison, a transformation is assigned to the supplemental frame.  Many
different transformations can be assigned before alignment of the frame is
complete.


This manual page offers an overview of alignment options; linked from this
page is a sub-page offering more detail on transformation
data files.


Transformations



The variables used to adjust alignment are called transformations; they map
points from the source image coordinate system to a target coordinate system
(the rendering coordinate system).


ALE supports three transformation classes -- translational, euclidean, and
projective -- as well as barrel/pincushion distortion correction.  The
translational class applies only translations to the inputs, changing only the
positions of images; the Euclidean class applies translations and rotations;
and the projective class applies general projective transformations.
Additionally, barrel/pincushion distortion correction can be applied to each
frame.  The Euclidean class is most appropriate for use with scanners, or as a
first pass for projective transformations.  The projective class and
barrel/pincushion distortion correction are most appropriate for use with
cameras.  Except when capturing flat scenes, ALE does not correct perspective
changes, so movement of cameras should ideally be constrained so that no large
translations occur.


Transformation Class Options



--translation     Only adjust the position of images
--euclidean       Adjust the position and orientation of images [default]
--projective      Use projective transformations.  Best quality, but slow.



For more information on barrel distortion correction, see the sub-page on 
transformation data files.


Transformation data file options



Transformations used in alignment can be loaded from, or saved to, a transformation data file.  This can be useful when performing
alignment in several passes, or when refining rendering options.  A
transformation data file is required for barrel/pincushion distortion
correction.


--trans-load=x    Load initial transformation settings from file x
--trans-save=x    Save final transformation data in file x




Alignment following



The --follow option hints that frames tend to be more closely aligned with
adjacent frames in the sequence than with the original frame.  This hint can be
useful even when initial alignment information is loaded from a file.


--identity        Frames align closely with the original frame.  [default]
--follow          Frames align closely with their immediate predecessor.




Match statistics



The match statistic indicates how well a transformed frame aligns with the
alignment reference image; it is used to select or reject transformations
during alignment.  After alignment of a particular frame is complete, ALE
displays the corresponding final match statistic.  If the value is close to
100%, then the frames are well aligned; very low values can indicate
misalignment; but even frames that are very well aligned typically do not
achieve 100% alignment.  For improving image quality, ALE works most
effectively when match values are lower than 100%.


Match threshold



A match threshold can be specified; no images with final match statistics
falling below this threshold will contribute to the final output.


--threshold=x     Min. match threshold; a perfect match is 100.  (0 is default)




Alignment failure



When an image fails to meet the match threshold, a transformation is still
assigned to the frame (e.g., for writing to a transformation
data file).  The assigned transformation can be either the optimal
alignment found (this is default) or the default transformation.


--fail-optimal    Frames beneath threshold are aligned optimally.  [default]
--fail-default    Frames beneath threshold keep their default alignment.




Alignment error metric exponent



The function calculated at each pixel to determine the match statistic is called
the alignment error metric, and is of the form (a-b)x.
The value x is called the error metric exponent, and is 2 by default.
Larger numbers indicate that alignment will be more influenced by smaller
image features.


--metric=x        Set the alignment error metric exponent.       (2 is default)




Alignment Channel Options



In calculating the per-pixel error metric, there are three ways in which ALE
can handle color channels.  By default, ALE adds the channels before
calculating the match, but it can also be configured to rely solely on the
green color channel, or to use all three channels separately.


--align-all       Align images using all color channels
--align-green     Align images using the green channel
--align-sum       Align images using a sum of channels [default]




Monte Carlo Alignment



Aligning large images can take a very long time if all pixels are examined in
determining the match statistic, so it is often desirable to examine a smaller
subset of pixels.  The Monte Carlo alignment option allows this.  The number of
pixels used is specified as a percentage, and smaller numbers usually mean
faster, but less precise, alignment.  For defaults, see the 
default settings page.


--mc <x>          Align using, on average, x% of available pixels (0 < x < 100)
--no-mc           Align using all pixels.




Alignment weight map



Typically, measured differences at each pixel in the alignment reference
image contribute equally to the match statistic.  To weight pixels differently,
a weight map can be used.  The scale of the map should correspond with that of
the alignment reference image, and if the upper-left corner of the map does not
coincide with the upper-left corner of the first frame in the sequence, then a
non-zero offset should be specified to indicate the difference.  See also exclusion regions.


--wm <f> <x> <y>  Use weight map image <f> at offset (<x>, <y>)




Frequency weighting



If ALE is compiled with FFTW support, then a high-pass-filtered version of
the alignment reference image can be used to weight reference image pixels'
contributions to the match statistic.  Frequency limiting can occur as a
fraction of the highest horizontal frequency, the highest vertical frequency,
or the highest average frequency.  Limit values should range between 0 (pass
all) and 1 (pass none).  If any limit is assigned a value of 1, no alignment
will occur, since all frequencies will have been excluded.  An output file can
optionally be specified for high-pass filtered data.



--fl <h> <v> <a>  High-pass filters: horizontal <h>, vertical <v>, average <a>.
--flshow <o>      Write high-pass filtered data to file <o>.




Certainty weighting



Certainty weighting causes contributions to alignment error to be weighted
by certainty values.



--cw              Weight alignment error by certainty.
--no-cw           Don't weight alignment error by certainty. [default]




Algorithmic weighting



This option writes the current alignment reference image and definition map
to specified files, executes a specified program with these arguments, and then
reads back alignment weights.  This option requires POSIX libraries, and
requires that ALE have been built with POSIX support enabled.



--wmx <e> <r> <d> Write reference <r>, definition <d>, execute `<e> <f> <d>`,
                  read weights <r> back.




Perturbation



The perturbation size determines the magnitude by which alignment parameters
are changed.  The size is initially set to be large, allowing large changes in
alignment to be evaluated, and is reduced as the locally optimal alignment is
found for each size.  When this size drops below a specified lower bound, the
frame is considered to be aligned.


Perturbation bounds



These options determine the upper and lower bounds for perturbation size.  The
perturb-upper and perturb-lower bounds apply to rotation (in arclength),
translation (in pixels), and the movement of the boundaries of a projected
frame (in pixels).  By appending the '%' character, values may optionally be
specified as a percentage of the number of pixels in the smallest image
dimension.  The rot-upper bound disables rotational perturbation above a
certain perturbation size (in degrees).  To disable alignment, set
perturb-upper to zero.


--perturb-upper=x Perturbation upper bound pixels/arclength    (14% is default)
                     ('x%' uses a fraction of the smallest image dimension.)
--perturb-lower=x Perturbation lower bound pixels/arclength   (.125 is default)
                     ('x%' uses a fraction of the smallest image dimension.)
--rot-upper=x     Rotation-specific upper bound in degrees    (32.0 is default)




Barrel/pincushion distortion adjustment multiplier and rate



When using barrel/pincushion distortion parameters, any frame-to-frame
adjustments to these parameters are made in a manner dependent on the
perturbation size.  A multiplier, the barrel distortion adjustment multiplier,
is used to determine the perturbation of these parameters, based on the generic
perturbation size.  Additionally, the frame-to-frame rate of change of each
barrel distortion parameter can be limited to a specified maximum.  To disable
frame-to-frame adjustment of barrel/pincushion distortion parameters, set
bda-mult to zero.  Setting bda-rate to zero disables rate limitation.


--bda-mult=x      Barrel distortion adjustment multiplier   (0.0001 is default)
--bda-rate=x      Barrel distortion rate of change maximum  (0.0004 is default)




Level of detail



Alignment at large perturbation sizes is usually carried out on
reduced-detail images.  To disable this, set lod-max to
log2(perturb-upper).


--lod-max=x       LOD scale factor is max(1, (2^floor(x))/perturb)  (1 is def.)




Perturbation Types (experimental)



Perturbations are normally performed in output image coordinates.  To perform
perturbations in source image coordinates, specify --perturb-source.


--perturb-output  Apply perturbations in output image coordinates. [default]
--perturb-source  Apply perturbations in source image coordinates.




Global Searching



In cases where important image features do not have sufficient overlap using
default alignment parameters (determined by --identity and
--follow), a number of translations can be applied to the default
parameters in order to find a new alignment starting point.  Since this process
searches the entire region of the alignment reference image, it is called a
global (as opposed to local) search.  To avoid misalignment, a minimum overlap
area can be specified.  In versions 0.8.1 and later, the search type 'points'
searches for a control point metric minimum.


--gs <type>       Set global search to <type>, one of:
                     local     Local alignment only [default]
                     inner     Alignment reference image inner region
                     outer     Alignment reference image outer region
                     all       Union of inner and outer
                     central   inner if below threshold or better; else, outer.
		     points    Align by control points.  Ignores gs-mo.   [0.8.1 and later]

--gs-mo <x>       Set <x> pixel min. overlap for global search. (16 is default)

Transformation data files are useful when performing alignment in several
passes or refining rendering options, and are necessary for specifying
barrel/pincushion distortion parameters.  They also offer a way to manually
specify alignment when ALE cannot automatically align images.  


Multiple-pass alignment


To align images in multiple passes, load the saved results of each previous
pass, as follows:


$ ale --trans-save=a.t <first pass arguments>
$ ale --trans-load=a.t --trans-save=b.t <second pass arguments>
$ ale --trans-load=b.t --trans-save=c.t <third pass arguments>
.
.
.




Rendering option refinement


To refine rendering options using the same alignment, first save the alignment
for the first option set, and then load the saved alignment information with
each subsequent option set, setting the perturbation upper bound to zero to
prevent a new alignment pass from occurring:


$ ale --trans-save=a.t <first option set>
$ ale --trans-load=a.t --perturb-upper=0 <second option set>
$ ale --trans-load=a.t --perturb-upper=0 <third option set>
.
.
.




Alignment file syntax (version 2)


There are two varieties of alignment file syntax that are both read and written
by ALE 0.7.0.  The most basic of these is version 2.  Version 3 is slightly
more complex, and is covered in the next section.

At the highest level, version 2 transformation data files contain the following
components: (a) a version command, and (b) a sequence of transformation
commands, one for each supplemental frame.  Each line of text should contain at
most one command, between which optional comments may be interspersed.  A
transformation command can be Euclidean, projective, or default.  Euclidean and
projective commands take several arguments, including the width and height of
the supplemental frame.  Default commands take no arguments.  Commands are
outlined in more detail below.


Version command



The version 2 version command is as follows:



V 2




Euclidean commands



The structure of a Euclidean command is as follows:



E <image width> <image height> <x-offset> <y-offset> <rotation-angle>




Projective commands



Projective commands map the four corners of the supplemental frame to four
points in the rendering coordinate system:



P <image width> <image height> <top-left-x> <top-left-y> <blx> <bly> <brx> <bry> <trx> <try>




Default commands


Default commands can be explicitly written as follows:


D



Alternatively, if there are more frames than alignment commands (euclidean,
projective, or default), then the last supplemental frames in the frame
sequence will be assigned the default command.


Comments


Comments can be inserted with the following syntax:


# This comment extends to the end of this line.  I can write anything I want here.




Alignment file syntax (version 3)


Version 3 syntax is required for specifying transformations for the original
frame, and for specifying barrel/pincushion distortion parameters.  


In version 3, the first transformation command is associated with the
original frame, instead of being associated with the first supplemental frame.
Also, barrel/pincushion distortion commands can precede each projective,
Euclidean, or default command.


Version command



The version 3 version command is as follows:



V 3




Barrel/pincushion distortion command


In version 3, barrel/pincushion distortion commands are supported.  Distortion
is modeled as a transformation affecting the distance of image features from the
image center.  The distorted distance is expressed as a polynomial function of
the undistorted distance.  Zeroth and first order coefficients are fixed or
automatically determined; additional coefficients can be specified explicitly,
using the following syntax:


B <n> <coefficient 2> <coefficient 3> ... <coefficient n+1>




Barrel/pincushion distortion commands should precede the projective, Euclidean,
or default transformation command for the corresponding frame.

ALE File Output



File output options determine the format in which rendered images are written,
and how frequently they are written.  Depending on the compilation options used,
available file output options vary.


Output Color Depth



Output color depth of 8 or 16 bits of precision per color channel can be specified,
for 24-bit or 48-bit color, respectively.  


--8bpc            Write 8 bit per channel output [default]
--16bpc           Write 16 bit per channel output




Extension-based file type determination



If ALE has been built with ImageMagick support, then the output file type can
be determined automatically by file extension.  This is the default behavior
for ImageMagick builds.  The --auto flag explicitly specifies that
the default behavior should be used; it generates an error on builds compiled
without ImageMagick support.  


--auto            Determine file type automatically




PPM Output



All builds of ALE support PPM output.  PPM can be written in plain (ASCII) or
raw (binary) format.  If ALE has been built without ImageMagick support, or if
the file type cannot be automatically determined by file extension, then raw
PPM output is used by default.


--raw             Write raw PPM output
--plain           Write plain PPM output




Incremental Output



By default, ALE writes intermediate results periodically throughout the rendering
process.  This behavior can be disabled, however, so that output is written only
after rendering is complete.


--inc             Produce incremental output.  [default]
--no-inc          Don't produce incremental output.




Undefined Values [0.8.3 and later]



By default, ALE colors undefined values black.  To assign nearest-neighbor colors
to undefined pixels, the --def-nn option can be used.  This option is only
available in versions 0.8.3 and later.


--def-nn <R>      Use nearest-neighbor defined values within             [0.8.3 and later]
                  radius <R>, zero outside.  Default radius is 0.

Control Points  [0.8.1 and later]



Control points are used for 2D and 3D alignment, and to constrain 3D scene
models.  Control point data is loaded from a control point file.  Scripts to
generate and manipulate control point files are included in the
scripts directory of the source distribution; the file
specification is outlined in the final section below.


Loading a Control Point File


The --cpf-load= option is used to load data from a control point file.


--cpf-load=<f>    Load control point data from file <f>   [0.8.1 and later]




Control Point File Format (version 0)


The version 0 control point file format consists of a version command followed
by a sequence of control points, with one control point per line of the file.


V 0
Control Point 1
Control Point 2
Control Point 3
.
.
.




Control points can be one of three types:



Type A control points


Type A control points specify a sequence of 2D points, one for each frame,
where each point is specified as a pair of floating point numbers.  If there is
no data for a frame, then "nan" should be specified.  E.g.:


A 20  30  nan nan 10  10  10  15
A 23  22  25  25  nan nan nan nan




Type B control points


Type B control points specify a 3D coordinate.  E.g.:


B 10 30 -400
B 10 15 -425




Type C control points


Type C control points specify both 2D and 3D data.  There is a single 3D point
specified, as well as one 2D point for each frame.  The 3D point appears at the
end of the line.  E.g.:


C 20  30  nan nan 10  10  10  15  10 30 -400
C 23  22  25  25  nan nan nan nan 10 15 -425

Irani-Peleg Renderer



ALE implements an iterative image reconstruction algorithm based on Michal
Irani and Shmuel Peleg's paper "Improving Resolution by Image Registration",
published in Graphical Models and Image Processing, Vol. 53, No. 3, May,
pp. 231-239, 1991, or available at:


http://www.wisdom.weizmann.ac.il/~irani/abstracts/superResolution.html


This algorithm iteratively performs two steps: first, an
approximation of T is projected, based on a filter approximating
dj, and data collected during alignment, to create a set of simulated input frames;
second, the per-pixel error -- between these simulated input frames and the
actual input frames -- is calculated, backprojected, and subtracted from the
approximation of T, resulting in a new approximation of T.


Initial Image Approximation



ALE uses the results of previous rendering steps as the initial image
approximation.



Projection and Back-projection filters


ALE provides command-line options for selecting forward-projection filters,
including box filters (release 0.4.2 and later) and custom filters (release
0.4.7 and later).  The back-projection filters are constructed so that the
normalized back-projection weight between a given pixel in the approximation of
T and a given pixel in an input frame is always equal to the
corresponding normalized forward-projection weight.  This differs from the
approach taken by Irani and Peleg.


Box Filter


ALE versions 0.4.2 and later implement a box filter with user-specified
diameter.  This is somewhat similar to the 'blur' operator used by some image
editing applications, and in some cases, may be an adequate approximation
for dj.


Custom Filters


ALE versions 0.4.7 and later implement support for device-specific custom
filters, including a filter calibrated for the IBM PC Camera Pro (XVP610) in
320x240 mode.  Configurability by color channel and pixel position in the input
frame is also supported, although the latter is not currently used by any
filter included with ALE.


stdin Filter


ALE versions 0.4.7 and later support limited configuration of filters at
runtime from standard input, implemented through a custom filter called
'stdin'.  This filter can be used with a script included in the source
distribution to calibrate filters for devices with unknown properties.


Transformation details



ALE's method of transforming pixel areas between coordinate systems
approximates transformed pixel boundaries with axis-aligned rectangular
regions.  Since boundaries are transformed into the coordinate systems of the
input frames, this approximation can be improved by using larger scale factors
(and hence reducing the size of transformed pixels).

ALE Technical Description  



Abstract



ALE combines a series of input frames into a single output image possibly
having:



    

  • Reduced noise.

  • Reduced aliasing.

  • Increased dynamic range.

  • Increased spatial resolution.

  • Increased spatial extents.




This page provides information on related work, models of program input, an
outline of renderers, and an overview of the algorithm used in ALE.  



Note: This document uses PNGs and HTML 4 character entities.



Related Work


ALE derives one of its rendering techniques from a
method developed by Richard Hook and Andrew Fruchter for combining dithered
images.


Steve Mann's work in Video Orbits
on increased spatial extents and the use of projective transformations has
influenced features incorporated by ALE.


ALE incorporates an iterative solver based on the work
of Michal Irani and Shmuel Peleg on image reconstruction.


Models of Program Input



Definition of Discrete and Continuous Images



Using R+ to represent the non-negative real numbers, a
discrete image D of size (d1,
d2) is a function 



D: {0, 1, …, d1 - 1}×{0, 1, …, d2 - 1} → R+×R+×R+



A continuous image I of size (c1, c2) is a function



I: [0, c1]×[0, c2] → R+×R+×R+






In this document, a member of the set
R+×R+×R+ is sometimes called an
RGB triple.


Definition of a Camera Snapshot



A camera snapshot is defined as an n-tuple consisting of:



    

  • A scene S.

  • A pyramid R with rectangular base.

  • A continuous image I.

  • A discrete image D.

  • A function i such that i(S, R) = I. 

  • A function d such that d(I) = D.




S represents a physical scene.



R represents the viewing volume of a physical camera.


The value I(x, y) is the RGB triple representing the radiance
that would be recorded from S by a directional light sensor
located at the apex of R and aimed at the point (x,
y) on the base of R.  The only constraint on the sensor
is that, given a fixed scene S,  it must return a unique value
for a given position and orientation.  This sensor is assumed to be the same
for all camera snapshots, and is called the canonical sensor.









Positioning of the canonical sensor







D represents the discrete pixel values reported by the
camera.



The composite function composite(d, i) represents the optical
and electronic properties of the camera. 


Definition of a Camera Input Frame Sequence



For positive integer N, a sequence of camera snapshots
{ C1, C2, …, CN }, defined by the
n-tuples { Cj = (Sj, Rj, Ij, Dj,
ij, dj) } is a camera input frame sequence if,
for all j and j', Sj =
Sj' and ij = ij'.


Definition of a Diffuse Surface


Given a camera input frame sequence { C1, C2,
…, CN }, defined by the n-tuples
{ Cj = (S, Rj, Ij, Dj, i,
dj) }, a surface in S is diffuse if the
radiance of each point on the surface (as measured by the canonical sensor) is
the same for all views Rj from which the point is visible.


Definition of the Extended Pyramid



If the view pyramids { R1, R2, …,
RN } of a sequence of N camera input frames all share a
common apex and can be enclosed in a single rectangular-base pyramid R
sharing the same apex and having base edges parallel to the base edges of
R1, then the smallest such R is the extended pyramid.
Otherwise, the extended pyramid is undefined.



If a camera input frame sequence has an extended pyramid R, then an
extended image is defined from R in a manner analogous to the definition
of the image I from the view pyramid R in the
definition of a camera snapshot.


Definition of a Projective Snapshot



A projective snapshot is defined as an n-tuple consisting of:



    

  • A continuous image Σ.

  • A continuous image I.

  • A discrete image D.

  • A projective transformation q such that I = composite(Σ, q)

  • A function d such that d(I) = D.




Σ represents the subject of the
snapshot (somewhat analogous to S in the camera snapshot).


D represents discrete pixel values reported by the physical
imaging device.


Definition of a Projective Input Frame Sequence



For positive integer N, a sequence of projective snapshots {
P1, P2, …, PN }, defined by the
n-tuples { Pj = (Σj, Ij,
Dj, qj, dj) } is a projective input
frame sequence if, for all j and j', Σj =
Σj'.


The first frame in the sequence of input frames is called the original
frame, and subsequent frames supplemental frames.


Construction of Projective Input Frame Sequences from Camera Input Frame Sequences



From a camera input frame sequence, define a continuous image
Σ as follows:


    


  • If an extended pyramid is defined for the set of camera input frames, then
Σ is the associated extended image.  

    


  • If an extended pyramid would be defined if all pyramids
Rj were translated to share a common apex, and the scene
S represents a physical configuration presenting to the camera only a
single planar, diffuse surface, then define Σ so that there
exists some projective transformation p such that Σ(p(x))
indicates the radiance at point x on the surface.




If such a Σ exists, then each camera input frame 



Cj = (S, Rj, Ij, Dj, i,
dj)



admits a projective input frame



Pj = (Σ, Ij, Dj, qj, dj)



for some qj, and these { Pj } form a
projective input frame sequence.


Definition of a Projective Renderer without Extension



For a projective input frame sequence { Pj = (Σ,
Ij, Dj, qj, dj) }, a
projective renderer without extension is an algorithm that outputs a
discrete image approximation of I1.  The assumptions used in
calculating the approximation vary across rendering methods.


Definition of a Projective Renderer with Extension



For a projective input frame sequence { Pj = (Σ,
Ij, Dj, qj, dj) }, a
projective rendering method with extension is an algorithm that outputs
a discrete image approximation of Σ.  The assumptions used in
calculating the approximation vary across rendering methods.


Renderers




Extension



All renderers can be used with or without extension (according to whether the
--extend flag is used).  The target image for approximation (either
Σ or I1) is generically called T.


Renderer Types



Renderers can be of incremental or non-incremental type.  Incremental
renderers update the rendering as each new frame is loaded, while
non-incremental renderers update the rendering only after all frames have been
loaded.



Incremental renderers contain two data structures that are updated with each
new frame: an accumulated image A with elements Ax, y
and the associated weight array W with elements Wx, y.
The accumulated image stores the current rendering result, while the weight
array stores information about contributions to each accumulated image pixel.


Renderer Details


These pages offer detailed descriptions of renderers.




Rendering Predicates



Renderers should output approximations of T when certain predicates
are satisfied.  Not all of these predicates are required for all renderers, and
renderers may produce acceptable output even when their predicates are not
satisfied.








Predicate
Explanation


Alignment
The projective input frame transformations qj are known.


Translation
All projective input frame transformations qj are 
translations.


Point sampling with simple optics
dj assigns Dj(x) = Ij(x).


Very large, uniform input sequence
A large number of input frames are provided, uniformly sampling the domain
of T.


Small radius
The radius parameter used with the rendering method is chosen to be
sufficiently small.


Barlett filter approximation
Convolution of T with a Bartlett filter remains an acceptable
approximation of T.


USM approximation
Applying the unsharp mask employed by the ALE --hf-enhance option to the
output of drizzling or merging produces an acceptable approximation of
T.


Correct Projection Filter
The projection filter used in Irani-Peleg rendering approximates
dj.


Low Response Approximation
Frequencies having low response in the Fourier domain representations of
dj need not be accurately reconstructed in the Fourier
domain representation of program output.


Convergence
Iterating Irani-Peleg on the input frames will eventually produce an
acceptable approximation of T, and the number of iterations chosen is
adequate to achieve this.  This predicate may entail the very large, uniform
input sequence predicate.






Summary of Rendering Predicates by Renderer



The following table indicates which rendering predicates are associated with
each renderer.  Note that renderers may produce acceptable output even when
these predicates are not satisfied.  Justification for non-obvious entries in
this table should appear in the detailed descriptions; for entries where this
is not the case, the value given should be considered unreliable.

Space Complexity


Image storage space in memory for all renderers without extension is
O(1) in the number of input frames and O(n) in the number of pixels per
input frame.  The worst-case image storage space in memory for all renderers
with extension is O(n) in the size of program input.


Algorithm



First, a merging renderer is instantiated.  Then,
program flags are used to determine what other renderers should be
instantiated.


An iterative loop supplies to the renderers each of the frames in sequence,
beginning with the original frame.  The drizzling and
merging renderers are incremental renderers, and
immediately update their renderings with each new frame, while the high-frequency enhancement and Irani-Peleg renderers do not act until the final frame
has been received.


In the case of the incremental renderers, the original frame is used without
transformation, and each supplemental frame is transformed according to the
results of the alignment algorithm, which aligns each
new frame with the current rendering of the merging
renderer.


Once all frames have been aligned and merged, non-incremental renderers
produce renderings based on input frames, alignment information, and the output
of other renderers.

Merging


Merging uses bilinear interpolation to determine each frame's contribution to
the accumulated image, and each contribution is assigned equal weight.
Sections below outline the merging algorithm and its properties.


Calculating the Overlapping Value



(This section is a very verbose explanation of bilinear interpolation.)


Determining what values from the new frame overlap pixels in the accumulated
image is an important part of merging.  Since transformations may involve
sub-pixel alignment, and the accumulated image may be configured to be of finer
resolution than the input frames, the manner in which these values are
determined is not necessarily obvious.  


ALE uses the following rules to determine the overlapping value:


    

  1. If the new frame overlaps the accumulated image pixel in such a manner that
the accumulated image pixel is aligned with a pixel in the new frame, then the
value of this pixel is the overlapping value.  

    


  2. If the point overlapping the accumulated image pixel falls on a line between
two pixels in the new frame, then the overlapping value is a linear
interpolation between these pixels in the coordinate system of the new frame.


    


  3. If the point overlapping the accumulated image pixel falls within a
quadrilateral outlined by the four closest pixels in the new frame, then the
overlapping value is a bilinear interpolation among these pixels in the
coordinate system of the new frame.

    


  4. If none of the above conditions apply, then there is no overlapping value
for the accumulated image pixel in the new frame.

    




Calculating the Merged Value



The merged value for an accumulated image pixel is a weighted average
between the current accumulated image pixel value and the overlapping value.
The weights are selected so that overlapping values from all frames contribute
with equal weight.


Definition of Merging



Merging a new frame replaces the existing value of each accumulated
image pixel with the merged value.


Properties



Density and false local minima



The merging method outlined above has the property of always updating a
dense set of pixels in the accumulated image, even when the accumulated image
is of finer resolution than the new frame.  This ensures that the area of
defined pixels in the accumulated image is dense and that any uniform change in
intensity is reflected uniformly over a dense area.  The absence of these
properties may cause alignment to fail due to entrapment in local minima, and
so merging is always used internally to create the renderings used by the
alignment algorithm.  Except in the case of a large pixel footprint, drizzling does not share these properties.


Convolution with the Bartlett (triangle) filter as the limiting case



Assuming predicates for translation, point sampling with simple optics, and
a very large, uniform input sequence, the result of merging is equivalent to
convolution of pixel data with the Bartlett, or triangle, filter.  This is
derived from the fact that bilinear interpolation of an image defined at
discrete points is equivalent to convolution with a Barlett filter.  This
property is still approximately true even when the translation predicate is not
satisfied, so long as large changes in scale do not occur.

High-Frequency Enhancement Renderer



The High-Frequency Enhancement Renderer is a built-in post-processing
step based on the unsharp mask technique, which has been used to enhance high
frequencies since the days of photographic plate processing (see, for example,
this
page).  This renderer acts after all other rendering steps have completed,
except for Irani-Peleg Iterative Image Reconstruction, which occurs afterward.


(The remainder of this text outlines version-specific information and offers no
further justification for rendering predicates.)













  







Release 0.3.1



The filter in release 0.3.1 acts on a square region, centered on the pixel
to be filtered, where the length of each side of the square is linear with the
scale factor (arbitrarily selected to be 2.5 times the scale factor).  The
pixel being filtered makes a positive contribution weighted with the total area
of the filter region, and all pixels coincident with the filter region make a
negative contribution weighted with the area in which the pixel is coincident
with the filter region.  


This filter was chosen primarily due to its implementation simplicity and
also for its satisfaction of the following two criteria: 


First, the filter value returned for a uniformly valued pixel array is zero.
 Hence, when the pixels in the region of the filter support do not vary in
value, the high-frequency filter returns zero.  This seems to be a
reasonable requirement for a high-frequency filter.  


Second, the filter support for a pixel closely corresponding to given pixel
in the original (unscaled) frame spans a region corresponding to a neighborhood
of pixels in the original frame that is roughly independent of the scale factor.  


In release 0.3.1, the filter result described above was divided by 100, so that
an enhancement factor of 1.0 would look reasonable for an image that had been
scaled up by a factor of 4.  This division step is replaced by a more general
and elegant normalization step in release 0.4.0.


Since this filter requires a square region of pixels centered on the pixel
to be filtered, it cannot operate near the boundary of an image.  We avoid this
problem in release 0.3.1 by not filtering near the boundary of images.


Release 0.4.0 and later



The filter in release 0.4.0 was modified from the filter in release 0.3.1 in two 
ways: 


First, the filter was extended to operate near the boundaries of an image.  When
necessary, the filter region is constrained so that it fits within the boundary
of the image.  (However, the notion of boundary used does not yet elegantly accommodate 
the non-rectangular boundaries that may occur when image extents are increased.)


Second, the filter was normalized so that the filtered pixel makes a
positive contribution with unit (1) weight, and all pixels coincident with the
filter region make a negative contribution with weight a/A, where
a is the area in which the pixel is coincident with the
filter region and A is the total area of the filter region.  


This change provides the following nice property that did not hold for the
filter in release 0.3.1:


Filtering and then scaling is almost the same as scaling and then filtering.


Hence, a given high-frequency enhancement argument in ALE will achieve
roughly similar results regardless of scale factor.  This behavior should be
less surprising than the behavior in 0.3.1, in which merely increasing the
scale factor argument could cause pixel values to become distorted as they
eventually collided with the limits of the image format.

Alignment


ALE aligns each supplemental frame, in sequence, with the merged rendering
representing all previous frames.  This page outlines the three supported
transformation classes, the algorithm used for alignment, and the properties of
the alignment algorithm.  Following this is a discussion of practical use of
alignment options, including alignment classes and alignment in the case of
extended renderings.


Transformations



ALE offers three classes of transformations: 





Translationsintroduced in version 0.0.0

Euclidean transformations (excluding reflections)introduced in version 0.1.0

Projective transformationsintroduced in version 0.2.0






Algorithm



Alignment proceeds by a deterministic search, beginning with an initial
transformation and modifying this transformation through a series of
perturbations.


The initial transformation may be loaded from a file or selected by default.
The default initial transformation is either the identity transformation or
(when the --follow option is specified) the most recently merged
frame's final alignment.  (Note that changes in release 0.5.0 are not reflected
here; these changes affect the interaction of the --follow and --trans-load
flags.)


Once the initial transformation is determined, an initial perturbation
amount is selected, and represents the step size by which each of the
transformation parameters are changed.  In translational or Euclidean
alignment, the perturbation amount is applied to translation -- in units of
pixels on the two image axes -- and rotation -- in units of degrees about the
image center.  (In version 0.4.8 and later, an additional configurable upper
bound constrains rotational perturbation separately, preventing, e.g., a
360 degree perturbation of rotation.)  In the case of projective alignment, the
perturbation amount is applied to the position of the corners of the projected
quadrilateral in units of pixels, where the projection is from the boundary
of the supplemental image into the coordinate system of the accumulated image.


If possible, transformation parameters are changed to decrease the error between the two images being
aligned.  The perturbation amount is halved whenever it is determined that no
parameter change of this size improves the alignment of the images.  A lower
bound on the perturbation amount determines when the alignment is complete.


The order in which parameters are considered for change is specified in the
source code, and has the following property: No modified parameter is
considered for further change until all other parameters have been considered.
A consequence of this property is that parameters are always considered in a
fixed (round robin) order.


When multiple levels of detail are used, the error may be calculated on
images with a reduced level of detail.  ALE versions 0.1.1 through 0.4.7 use a
level of detail twice as fine as the perturbation amount for perturbation
amounts larger than two, and full detail otherwise.  Later versions default to
this behavior, but can be configured differently.  Earlier versions do not use
reduced levels of detail.


Properties



Several assumptions were made throughout the design and testing of the
algorithm outlined above.  These assumptions are outlined below.


The algorithm is based on a hill-climbing approach, which requires that any
local minimum reachable from the starting point by traveling a path of
decreasing error is also a global minimum (or, in this case, the correct
alignment).  While it is possible that the algorithm outlined above succeeds in
some cases for which hill-climbing fails, it is still susceptible to entrapment
in local minima.


As outlined above, depending on program options, transformation parameters
may be changed by perturbations of several units (degrees or pixels) early in
the alignment process.  As long as no change of this magnitude moves the
transformation out of the 'bowl' in which the minimum error -- and hence
correct alignment -- lies, this is not a problem.  However, it might break in
some cases where a hill-climbing approach would succeed.  (Notably, simulated
annealing suffers from a similar problem, and it seems likely that a case could
be constructed in such a way that the algorithm outlined above -- like
simulated annealing -- could, contrarily, succeed where hill-climbing fails.)


Finally, the use of reduced level-of-detail relies on a high signal-to-noise
ratio at low frequencies.  Fortunately, this assumption seems to generally
hold, but camera defects or radio interference could violate the assumption,
possibly resulting in misalignment.


Use of Alignment Classes



ALE is likely to be most useful when corresponding regions of different
frames can be aligned by one of the available alignment classes.


As described by Steve Mann in his work on Video Orbits, the projective
transformation offers particular versatility for camera imaging of (ideal
Lambertian) flat scenes.  In this case, any change in camera position and
orientation can be corrected as long as points always have a defined projection
onto the rendering plane (for which ALE uses the base of the pyramid
R1).


In camera imaging of scenes with depth, correction for orientation is almost
the same as for flat scenes, since, if focus and lens distortion is ignored, a
scene with depth is indistinguishable from a flat scene from the perspective of
a camera whose position is fixed.


For sequences of camera images with small changes in position or
orientation, the projective transformations for alignment may closely
approximate Euclidean transformations; in this case, using Euclidean
transformations may achieve similar results and may require less time for
alignment, since there are fewer parameters to tweak (three parameters
instead of eight).


In the case of flatbed scanners that preserve the relative height and width
of scans, any change in the position or orientation of flat objects can be
corrected using the Euclidean alignment class.



If a flatbed scanner does not preserve relative height and width, but does
preserve straight lines, then any change in the position or orientation of flat
objects can be corrected with the projective alignment class.


However, even if a transformation is within the alignment class used, the
alignment algorithm may still be unable to determine large transformations.


Alignment in the case of Extended Renderings



By using the --extend flag, ALE can be used to create image mosaics spanning
a spatial region larger than that represented by any single image in the frame
sequence.  In these cases, if adjacent frames in the sequence tend to be more
closely aligned with each other than they are with the original frame, it may
be helpful to also use the --follow flag as a hint to the alignment algorithm.

Monte Carlo Error Function


Monte Carlo alignment can decrease the time required to align large images,
since calculating transformations for every pixel is usually expensive.
Sections in this page describe the motivation for Monte Carlo alignment, the
ratio calculations used, the sampling algorithm, cache behavior for the
algorithm, randomization approaches, typical deviations from the specified
ratios, special handling of level-of-detail, and practical observations
regarding the use of Monte Carlo alignment.


Motivation


Transforming large numbers of points in order to determine alignment error can
be very computationally expensive.  One approach to mitigating this expense is
to use reduced level-of-detail.  However, using reduced level-of-detail can
also reduce alignment precision.  In particular, reducing the level of detail
by a factor of two can make impossible the task of precisely aligning a
horizontal line one pixel high.  However, if just a few pixels from the line
are sampled at full detail, exact alignment is possible.


Ratio Calculations



In Monte Carlo alignment, a ratio 



s = (expected # of pixel
samples) / (# of total pixels in the accumulated image)



is specified.  From this ratio, a new ratio 



u = (expected # of unsampled pixels) / (expected # of sampled pixels)



is calculated.  Pixels are sampled in such a manner that u is
approximately satisified.  


Sampling Algorithm



Pixels are considered in order of index, where the accumulated image pixel
at position (i, j) is numbered with an index (i * width + j).
In order of index, we skip and sample pixels in such a manner that the
expected size of a run of consecutive skipped pixels preceding a sampled pixel
is u.  We select the size of each run of consecutive skipped pixels as
follows:


If 2 * u is an integer, then we draw uniformly from integer values in
the interval [0,2u].  If it is not an integer, then we draw from integer values in
the interval [0,2u + 1] in such a manner that integer values in
[0,2u] are equally likely to be chosen.  (There is only one probability
distribution of this kind that satisfies the expected value u.  Version
0.4.3 deviates slightly from this distribution, and so a deviation in the
expected value of s occurs, as outlined in this table.  This problem is fixed in version 0.4.4.)


(Also, see the section below on interaction with level-of-detail.)


Cache behavior



Since indices are monotonically increasing in memory address, this approach
to sampling may make effective use of memory cache where other approaches (e.g.
repeated random draws from the entire index space) would not.  


Randomization


ALE versions 0.4.7 and earlier do not reseed the pseudorandom number generator,
and so a new random subset is selected every time the error function is
evaluated.  Hence, as more or fewer of the pixels critical to alignment are
sampled, the reported alignment can worsen or improve even in the absence of
any change in transformation.


With this approach, since many transformations are inspected during the
alignment of any given frame, it is likely, especially with greater precision
of alignment, that some measured differences between transformations are due to
a difference in sample sets rather than a difference in alignment accuracy.


By reseeding the pseudorandom number generator, ALE versions 0.4.8 and later
instead use a consistent set of pixels from the accumulated image when
comparing two transformations.  Tests sampling 3% of pixels from a set of
320x240 frames indicate that this approach improves alignment.


Sampling characteristics


For an image with 100,000 pixels and specified
s in the interval [0.005,0.995], ALE's sampling method results in
a ratio s within 0.000003 of the specified s.  This number 
improves with image size.  These results are outlined in the table linked
above.  However, note that s only represents an expected value, and the actual number
of sampled pixels may vary by more than the numbers given here.


Interaction with level-of-detail



When reduced level-of-detail is used, the number of reduced-detail pixels
sampled is taken to be a percentage of the total number of pixels in the
full-detail image, rather than as a percentage of the total number of pixels in
the reduced-detail image.  (When this fraction of pixels in the full-detail
image is more than the number of reduced-detail pixels available, all
reduced-detail pixels are used.)  This may improve the likelihood of successful
alignment, but may also add overhead to the alignment process.


Use of Monte Carlo Alignment



  If it is not known in advance what settings will work well for a series of
frames, it may be desirable to begin by sampling a small percentage of pixels,
saving the results of alignment, and then, if the output suggests that proper
alignment is occuring, performing more precise alignment with a larger
percentage of pixels on later passes, using smaller perturbation upper bounds.
If alignment problems occur on the first pass, the percentage of pixels can be
increased and alignment performed again.

Error Functions










ALE


Image Processing Software

Local Operation

[ Up | Monte Carlo ]


Error Functions



Error functions are used to determine whether a transformation is "good" or
not, and in particular, whether one transformation is better or worse than
another.  In particular, a smaller error indicates a better transformation.




ALE defines error functions for each pixel of the accumulated image, and
also a comprehensive error function that summarizes the error over all 
pixels.  


Per-Pixel Error Functions



Since differences in exposure may alter the absolute values of pixels even
in images that are perfectly aligned, ALE usually normalizes the images so that
overall image intensity matches.  This normalization step does not affect the
pixel values contributing to the merged image, but it does affect the values
with which the per-pixel error function is calculated.  (The normalization
step is skipped when --extend or --follow is specified.)





The per-pixel error function for pixel (i, j) in the accumulated
image A, frame B, and transformation T, is:




p(i, j, A, B, T) = Abs( A(i, j) - B(T_inverse(i, j)) )metric_exponent






where Abs() is the absolute value function and B(T_inverse(i, j))
is the overlapping value described in the merging section.
If not specified by the --metric option, metric_exponent defaults to 2.0
for ALE versions 0.1.0 and later, or 1.0 for version 0.0.0.


In addition to the per-pixel error function, a per-pixel maximum error
estimator is calculated, as follows:




p_max(i, j, A, B, T) = Max( A(i, j), B(T_inverse(i, j)) )metric_exponent







Comprehensive Error Functions


There are two varieties of comprehensive error function used by ALE: an
exhaustive error function and, in versions 0.4.3 and later,  a
Monte Carlo error function.  Whereas the exhaustive function
evaluates the error for each pixel in the accumulated image, the Monte
Carlo function evaluates only a subset of pixels.  

If we consider Sum[] to provide the sum over whatever
subset of pixels we are sampling (including possibly the set of all pixels), then
the comprehensive error function, for accumulated image A, frame
B, and transformation T, is:




E(A, B, T) = (Sum [ p(i, j, A, B, T) ] / Sum [ p_max(i, j, A, B, T) ])(1/metric_exponent)

Drizzling Renderer



ALE versions 0.4.1 and later implement a drizzling algorithm based on that
outlined in research by Richard Hook and Andrew Fruchter.1  


Algorithm



In the drizzle rendering method, pixels from source images are considered to
span an area smaller than the original source pixel (a 'reduced footprint');
these source images with reduced pixel footprint are transformed for alignment,
and the reduced-area pixels from all transformed source images are combined to
form the target image, where each source pixel contributes to each target pixel
linearly with the area of overlap after transformation.  


ALE uses an approximation to the above approach, wherein the area of overlap
is calculated in the coordinates of the source image and then multiplied by a
factor approximating any difference in scale between the source and target
images; for the purpose of these calculations, the region of the target pixel
is approximated by a rectangle in the source coordinate system having all sides
parallel to the source image coordinate axes.


Properties



Assuming small drizzling radius, drizzling is approximately the same as
convolution of discrete pixel data with a box filter having the same radius as
the chosen drizzling radius.  For a very large, uniform input sequence, point
sampling with simple optics, and sufficiently small radius, drizzling should
provide an acceptable approximation of T.



1 More information on drizzling can be found in the paper by Hook and Fruchter,
"Variable-Pixel Linear Combination", published in vol. 125 of the ASP
Conference Series (eds. Gareth Hunt and H. E. Payne).  This paper was also

Using an 8-bit ALE build with 16-bit ImageMagick truncates the most
significant bits of pixel data on 16-bit input image files.  This does not
affect 8-bit input files.  This bug does not affect the Windows package.

Fixed in patch 1.

        projective transformations as described in the file a.t.





ale --3dv 0 out.png --projective frame*.png null:



        Render output file out.png from inputs frame*.png, using a
        3D scene model to determine transformations.





ale --visp last:sinc*lanc:6 sf:0 out/ .jpg in/*.jpg null:



        Render a video stream from files in/*.jpg to the directory out/,
        stabilizing to the first frame, with a lanczos-windowed sinc filter.

More detailed manuals describing options and internal algorithms are available
for certain versions of ALE.  See SEE ALSO below for more details on other
manuals.



HELP OPTIONS
A listing of available help options can be obtained by invoking ale --hu.



ENVIRONMENT
The wrapper script ale recognizes the following environment variables:




ALE_BIN



        ALE executable to use.





DCRAW



        dcraw raw extraction tool to use.





EXIF_UTILITY



        EXIF extraction utility to use.

Devices


Device specification is optional.  Specifying a device allows automatic
determination of point-spread functions,
refinement of the correspondence between incident light and pixel values (e.g.
power law), and refinement of certainty calculation.



--device <d>      Set the capture device to <d>.




Available devices are as follows:




Available device types

canon_300d_raw_linearCanon 300D (Digital Rebel) raw, linear data.


canon_300d_raw_linear+50mm_1.4Canon 300D with EF 50mm f/1.4 lens, unspecified aperture.

canon_300d_raw_linear+85mm_1.8Canon 300D with EF 85mm f/1.8 lens, unspecified aperture.


ov7620_raw_linearOmniView OV7620 in raw RGB, linear mode.


xvp610_640x480IBM PC Camera Pro (XVP610) in 640x480 mode.


xvp610_320x240IBM PC Camera Pro (XVP610) in 320x240 mode.





These device options are described in more detail below.


Canon 300D (Digital Rebel)


Direct support for CRW files depends on the ImageMagick configuration, and
may not be available on all platforms.  Dave Coffin's dcraw program, invoked with
arguments -d -4, will produce a raw, linear PPM file suitable for use with this
device configuration.  JPEG files produced by the 300D cannot be directly used
as inputs for this configuration, since they are gamma-corrected rather than
linear.


OV7620


Standard OV7620 drivers may not include options for setting raw RGB or linear
modes.  Linux users may apply a driver patch to access
these modes.  Setting the module option rgb_raw=2 places the camera
into the desired mode.


XVP610


Users of XVP610 cameras and Linux may wish to apply a driver patch.  This version of ALE expects that this patch has been applied.

Rendering Chains

The ALE incremental renderer is configured using rendering chains.  Rendering chains are
constructed hierarchically from: invariants, SSFEs (scaled sampling filters
with exclusion), SSFs (scaled sampling filters), and sampling filters.  Each of
these components is described in a section below.  Defaults are outlined in the
final section.


Chains


The chain is the top level of the rendering chain hierarchy, and is composed of a
sequence of invariants.  Syntactically, a chain is specified as a number of
invariants separated by commas:



invariant1,invariant2,invariant3,...,invariantn



Each rendered pixel is assigned a value at the first invariant whose weight
exceeds the weight threshold, or otherwise at the last invariant in the sequence.


Chain Options


--wt <w>          Set weight threshold for defined pixels [default is 0.8 in v0.8.0; 0.1 in v0.8.1 and later]
--dchain <g>      Use chain <g> to render the default output.
--ochain <g> <o>  Use chain <g> to render output file <o>.
--achain <g>      Use chain <g> to render the alignment reference image.
--3d-chain <g>    Use chain <g> by default to render 3d output.  [0.8.4 and later]

Invariants


Invariants determine whether the rendered pixel value should be taken from a
single frame, or from an average of all frames.  If from a single frame, it can
be the first, last, minimal, or maximal pixel value.  Averages include mean
and, in versions 0.8.1 and later, the median.  By default, the mean is used.
(Note that using the median value may require allocation of a quantity of
memory linear in the number of frames.)  The syntax is as follows:




Invariant types

SyntaxDescription


avg:<SSFE>Mean value


median:<SSFE>Median value


max:<SSFE>Maximum value


min:<SSFE>Minimum value


first:<SSFE>First value


last:<SSFE>Last value


<SSFE>Same as avg:<SSFE>




Scaled Sampling Filter with Exclusion (SSFE)


SSFEs qualify SSFs, indicating whether exclusion regions should be honored.

Scaled Sampling Filter (SSF)


SSFs indicate whether filtering should occur at the resolution of the output
image, or at the minimum of input and output image resolutions.  The former prevents loss
of details; the latter prevents aliasing.

Point Spread Functions

The ALE Irani-Peleg renderer uses a point-spread function to model the optical
and electronic properties of the capture device used.  The PSF can be specified
in terms of one linear and one non-linear component.


PSF specification


The PSF can be explicitly specified by using one or both of the psf options.


--lpsf <p>        Set linear colorspace point-spread function to <p>
--nlpsf <p>       Set non-linear colorspace point-spread function to <p>



Available explicit point-spread functions are as follows:


box=<d>           Set the PSF to a box filter with diameter <d>.
circle=<d>        Set the PSF to a circular filter with diameter <d>.
stdin             Specify a custom filter at runtime.
stdin_vg          stdin with vertically-oriented gaps after every 8th pixel.
<p>+<p>           Summation of two functions
<p>^<p>           Convolution of two functions.
<n>*<p>           Multiplication by a scalar <n>.



If a device is known to ALE, then its PSF can be implicitly set with the
--device option.  (See the device page
for more information.)  If a device is not specified, then the default linear
PSF component is box=1.  The non-linear PSF component is disabled
by default.


Determining the PSF


The PSF can be approximated based on images of known scenes.  The ALE source
distribution includes an experimental script that numerically approximates the
PSF in this way (d2/render/psf/ale-psf-calibrate).  Other, more
efficient methods for approximating the PSF are likely possible, however.

3D Scene Reconstruction (Experimental)


In general, 3D modeling of scenes may allow handling of cases that per-frame
projective transformations do not allow, such as registering frames having
different viewpoints over a non-flat or specular scene, or recovery of depth
from frames having different viewpoints.  ALE's implementation of 3D scene
reconstruction is considered experimental in versions prior to 0.8.3.


Models


The method of modeling used in 0.8.2 and later is spatial subdivision based on
regions of interest, followed by iterative update of the estimated occupancy
and color of each region of interest.  (For a general discussion of occupancy,
see Hans Moravec's work on depth recovery.)  In 0.8.1, the method of modeling
is decomposition and deformation of a surface.  In earlier versions, a
per-frame, per-pixel model of depth is used.


Recovered Color and Depth Output


The color and depth output options provide a reconstruction of the scene as
viewed from a particular frame's vantage point, or from an arbitrary camera
view [0.8.2 and later].  In 0.8.2 and later, normalization of output values by
accumulated occupancy can optionally be disabled for unfiltered views.  Version
0.8.3 adds support for options --et and --3dpx, which can be useful for 3D
cropping applications.  --et specifies the minimum accumulated weight required
for a pixel to be defined, allowing refinements of crops based on clip planes
(--rc and --fc) established prior to scene
reconstruction, whereas --3dpx specifies a region of space to be removed 
after scene reconstruction.  0.8.3 uses depth image pixels to determine such spatial regions,
leaving the pixels undefined, whereas 0.8.4 removes scene geometry prior to
rendering, allowing rendering of background objects after the foreground has been removed.

                         <xmin> <xmax> <ymin> <ymax> <zmin> <zmax>



Filtering [0.8.4 and later]


Version 0.8.4 adds support for filtering color values from the inputs to
produce final color renderings.  This is now the default.  Determining surface
depth and gradient for filtering the inputs draws from a set of depth pixels
within a disc whose radius can be specified with the --3d-dmr and --3d-fmr
options.



Filtering color from views distributed on a disc (about the camera origin) of
specified aperture allows simulation of focus effects; such effects can be
controlled with the --focus option.



--3d-filter       Use filtering for 3D color output.                    [default]
--3d-nofilter     Don't use filtering for 3D color output.

                     Space-separated options may include zero or more of:

                            median    median of views




Camera parameter adjustment


In versions 0.8.1 and later, camera parameters can be adjusted according to
control points to decrease the error between points in different frames.
Perturbation bounds for adjustment can be specified, including an additional
upper bound on view angle perturbation, and a stereo threshold can be set for
discarding control points after adjustment is complete.  An initial camera view
angle can also be specified.  Versions 0.8.2 and later allow calculation of
error by median rather than mean, and also allow disabling of adjustment of
orientation and/or position.



--view-angle <x>  Set the initial diagonal view angle to <x> degrees.
                     (Default is 43.7 degrees or device-specific.)
--cpp-upper=<x>   Set upper bound <x> for camera parameter perturbation,           [0.8.1 and later]
                  in pixels or degrees [default is 32]                            
--cpp-lower=<x>   Set lower bound <x> for camera parameter perturbation,           [0.8.1 and later]
                  in pixels or degrees [default is 0.125]                    
--va-upper=<x>    View-angle perturbation upper bound in degrees  [default is 32]  [0.8.1 and later]
--st <x>          Control point stereo threshold is <x> pixels.    [default is 4]  [0.8.1 and later]
--cpp-err-mean    Use RMS error to determine camera parameters.         [default]        [0.8.2 and later]
--cpp-err-median  Use median error to determine camera parameters.                       [0.8.2 and later]
--vp-adjust       Adjust the view point                                 [default]        [0.8.2 and later]
--vp-noadjust     Do not adjust the view point                                           [0.8.2 and later]
--vo-adjust       Adjust the view orientation                           [default]        [0.8.2 and later]
--vo-noadjust     Do not adjust the view orientation                                     [0.8.2 and later]



Transformation data files [0.8.2 and later]


Transformation data file options allow reading and writing of camera position,
orientation, and view angle information.



--3d-trans-load=x Load initial transformation settings from file x                       [0.8.2 and later]
--3d-trans-save=x Save final transformation data in file x                               [0.8.2 and later]



Transformation data file format [0.8.2 and later]


The transformation data file uses the following format, starting with a version
command, and then describing view angle and euclidean transformation of each
frame in turn:



W 0
V <view angle>
E <width> <height> <X> <Y> <Z> <P> <Y> <R>
V <view angle>
E <width> <height> <X> <Y> <Z> <P> <Y> <R>
.
.
.
V <view angle>
E <width> <height> <X> <Y> <Z> <P> <Y> <R>



Model costs [0.8.1 only]


After the cameras are adjusted, a 2D surface is decomposed and deformed to
reduce local cost measures, calculated from angles between neighboring
triangles, edge lengths, and differences in color between different views.
Multipliers for edge length and angle costs can be specified on the
command line.



--ecm <x>         Set edge length cost multiplier <x>.         [default is 0.001]  [0.8.1 only]
--acm <x>         Set angle cost multiplier <x>.               [default is 0.001]  [0.8.1 only]



Model rules [0.8.2 and later]


In versions 0.8.2 and later, clip planes can be specified, and a color falloff
exponent for pairwise occupancy estimation can be specified.  Larger exponents
are more forgiving of color differences between pixels in different frames.
In versions 0.8.3 and later, error contributions from cameras outside of the
generating pair can be assigned non-zero multipliers (--tcem), the
number of occupancy and color update iterations can be specified
(--oui), the number of points in space generated for each pixel
pair can be specified (--pa), and the type of frame pairings can
be specified (--pc).

Rendering

Rendering determines how an output image is constructed from a series of
aligned input frames, and occurs in two stages: incremental rendering and
Irani-Peleg rendering.  Additional rendering options include exposure
registration, certainty-weighted rendering, spatial extension, range extension,
scaling, and Bayer pattern specification.  Experimental options for video
stream processing are also available.


Incremental Rendering


The incremental renderer uses configurable rendering chains to determine the
output image.  It can increase resolution and reduce aliasing, but it cannot
reduce blur.  For more information on rendering chains, see .


Irani-Peleg Rendering


The Irani-Peleg renderer uses configurable point-spread functions to model
blur, which is then reduced by an iterative backprojection technique.  By
default, mean correction values are used at each iteration step, but median
correction can also be specified.  For more information about point-spread
functions, see .  For iteration defaults, see
.




--ips <i>         Run <i> iterations.
--ip-mean         Use the mean correction [default]
--ip-median       Use the median correction


Exposure Registration


By default, ALE adjusts an exposure model to minimize differences in tone
between frames.  The option --exp-noregister indicates that exposure
should be assumed uniform across all frames.  In this case, no adjustment is
performed.  The option --exp-meta-only indicates that only exposure
information included in the image files should be used for registration.
Currently, EPPM is the only type of exposure metadata supported by this option;
for more information, see .


--exp-register    Register exposure between frames.  [default]
--exp-noregister  Assume uniform exposure across all frames.
--exp-meta-only   Use only image metadata for registering exposure.


Color Adjustment


To adjust the color of the output image (e.g., for white balance), the
--exp-mult= option can be used.


--exp-mult=c,r,b   Adjust all channels by <c>, red by <r>, and blue by <b>.


Certainty-weighted Rendering


The exposure model includes an associated certainty function, which
quantifies the reliability of sensor measurements.  By default, this function
is raised to the zeroth power, to obtain uniform certainty for all measurements.
To specify a different certainty exponent, the option --cx can be
used.  This option is best used in combination with --exp-extend (see
below) and --ips.  For defaults, see .


--cx <x>          Render with certainty exponent <x>
--no-cx           Render with uniform certainty.


Scale factor


Rendering with a larger scale factor results in image output of the specified
larger scale.  Larger scales can improve alignment precision and output image
quality, but can also increase alignment and rendering times.


--scale=x         Scale images by the factor x, where x > 0.     (1 is default)


Image extents


The --extend option records pixel data that falls outside of the region of the
first frame in the sequence.  This can be useful for providing additional
alignment constraints or creating panoramic image mosaics.  (For mosaics, see
also the description of the --follow option in .)


--extend          Increase image extents to accommodate all pixel data.
--no-extend       Don't increase extents; crop to original frame. [default]


Exposure extents


By default, ALE restricts the output range to that of the original frame.
To adjust the output range to accommodate the ranges of all input frames,
specify --exp-extend.  For defaults, see 


--exp-extend      Extend range to include all calculated values.
--exp-noextend    Restrict to the original frame's range.


Bayer pattern specification


Many cameras sample only one color channel per output pixel.  To ignore the
other channels, a Bayer pattern can be specified.


--bayer <b>       Set the Bayer pattern to <b>, one of:
                    (clockwise from top left pixel)
                      rgbg      Red-green-blue-green
                      gbgr      Green-blue-green-red
                      grgb      Green-red-green-blue
                      bgrg      Blue-green-red-green
                      none      RGB-RGB-RGB-RGB
                  Default is none or device-specific.


Video stream processing (Experimental)


If a sequence of frames represents a video stream, then, in addition to
producing a single output image, ALE can also produce one or more sequences of
processed frames, corresponding to one or more occurrences of the
--visp option.  This option has its own associated scaling option,
as well as an option to show excluded regions as dimmed wherever possible.


--visp <args>     Process a video sequence.
                     <args> are:
                         <chain> <stabilization-type> <prefix> <suffix>
                     <chain> is an incremental rendering chain.
                     <stabilization-type> is one of:
                         ma:<x>     Moving average over 2*<x> + 1 frames
                         sf:<x>     Stabilize to single frame number <x>
                         identity   Same as ma:0
                     <prefix> is an output file prefix
                     <suffix> is an output file suffix
--visp-scale=<x>  Use scale <x> for VISP output.  (default is 1.0)
--exshow          For single-invariant chains, show --ex regions dimmed.


Video stream processing example


To mimic the behavior of repeated applications of the 0.6.0
--replace option over a sequence of frames, the following
--visp option could be used.


--visp last:nex:triangle:2 sf:0 frame .jpg



For better filtering, the following option could be used instead:


--visp last:nex:sinc*lanc:6 sf:0 frame .jpg

User Interfaces


ALE currently supports two user interface types.  The traditional interface
is the stream interface, which produces only printing characters and
whitespace.  If ALE is compiled with IOCTL support, additional information can
be provided through the tty interface, which is default.



--ui=<type>       Set user interface to <type>, one of:
                     stream
                     tty [default]





ale-0.9.0.3/doc/user/defaults/0000755000175000017500000000000011164421407016200 5ustar  dhilvertdhilvertale-0.9.0.3/doc/user/defaults/index.xml0000644000175000017500000000566411164421407020044 0ustar  dhilvertdhilvert




  Default Settings


ALE offers five different default settings, each of which emphasizes
image quality, speed, or some other rendering characteristic, as follows:


--q0              Low quality, high speed. [default]
--qn              Low noise, moderate speed.
--q1              Moderate quality and speed.
--q2              High quality, low speed.
--qr              Range-extended high quality.



These settings specify defaults for other options: --dchain,
--achain, --3d-chain, --ips, --exp-extend, and
--cx.  For more information about these options, see  and .  Details regarding
these defaults are provided in the following sections.


High speed (--q0)


--q0 emphasizes speed over image quality.  This option is default, and
sets other options' defaults as follows:


--dchain fine:box:1,triangle:2
--achain triangle:2
--ips 0
--exp-noextend
--no-cx
--3d-chain fine:box:1,triangle:2



Low noise (--qn)


--qn emphasizes low noise over resolution and rendering speed, and
sets the following defaults:


--dchain sinc*lanc:6
--achain sinc*lanc:6
--ips 0
--exp-noextend
--no-cx
--3d-chain sinc*lanc:6




Balanced quality and speed (--q1)


--q1 balances image quality and rendering speed, offering higher
resolution than --qn.  As this option uses median values, its memory use
is linear in the number of input images (rather than constant).


--dchain median:fine:sinc*lanc:8,triangle:2
--achain triangle:2
--ips 0
--exp-noextend
--no-cx
--3d-chain median:fine:sinc*lanc:8,triangle:2




High quality (--q2)


--q2 favors image quality over rendering speed, offering greater
emphasis for high-frequency details than --q0, --qn,
or --q1.  It depends on the --lpsf and
--nlpsf options, which can be set indirectly via the
--device option.  (More information about these options can be
found in  and .)  --q2
sets the following defaults:


--dchain triangle:2
--achain triangle:2
--ips 4
--exp-noextend
--no-cx
--3d-chain median:fine:sinc*lanc:8,triangle:2




Range extension (--qr)


--qr is similar to --q2, but offers improved
rendering when input images have been taken with unequal exposures.  In other
cases, it may exacerbate noise in light and dark regions.  This option sets the
following defaults:


--dchain triangle:2
--achain triangle:2
--ips 6
--exp-extend
--cx 0.7
--3d-chain median:fine:sinc*lanc:8,triangle:2

Exclusion Regions


ALE offers exclusion regions as a way to disallow certain areas from being
used in alignment and (optionally) rendering.  Spatial coordinates are
expressed in the rendering coordinate system (prior to scaling).  In cases
where the default transformation is used with the original frame, this is
identical to the unscaled original frame coordinate system, taking the
upper-left corner to be (0, 0).  Frame numbering begins with 0, which represents
the original frame.


Rectangular Exclusion


All specified volumes are excluded from alignment (except where they affect
the alignment reference image), and are excluded from rendering by default.
(See  for information on how to ignore exclusion
regions.)  Exclusion region syntax is as follows:


--ex <args>       Exclude a specified volume.
                     <args> are space-delimited horizontal,
                     vertical, and frame limits:
                         <xmin> <xmax> <ymin> <ymax> <fmin> <fmax>


Cropping


Cropping excludes the spatial complement of an area over a specified set of
frames.


--crop <args>     Exclude the spatial complement of an area over a
                  specified set of frames.  <args> are:
                         <xmin> <xmax> <ymin> <ymax> <fmin> <fmax>

Extended PPM (EPPM) Files


EPPM is an extension to the PPM file format that allows specification of
metadata.  The header of an EPPM file conforms to the following template:



P6#E
# Tag1: Value
# Tag2: Value
# Tag3: Value
# .
# .
# .
Width Height Maxval
Data




Tags recognized by ALE are outlined below.


Black level


The black level tag specifies a value that should be subtracted from
all pixels in order to achieve linearity.  A modified version of dcraw (darcs repository) can be used to generate files
containing this tag.



# Black-level: <value>



Exposure tags


Exposure tags can be used for determining tonal registration through
specification of shutter speed, aperture, and ISO sensitivity (or gain).



# Shutter: <value>
# Shutter: 1/<value>
# Aperture: <f-number>
# ISO: <value>
# Gain: <value>

Alignment


Alignment compares each supplemental frame in the sequence with an intermediate
incremental rendering known as the alignment reference image.  Based on this
comparison, a transformation is assigned to the supplemental frame.  Many
different transformations can be assigned before alignment of the frame is
complete.



This manual page offers an overview of alignment options; see also .


Transformations


The variables used to adjust alignment are called transformations; they map
points from the source image coordinate system to a target coordinate system
(the rendering coordinate system).



ALE supports three transformation classes -- translational, euclidean, and
projective -- as well as barrel/pincushion distortion correction.  The
translational class applies only translations to the inputs, changing only the
positions of images; the Euclidean class applies translations and rotations;
and the projective class applies general projective transformations.
Additionally, barrel/pincushion distortion correction can be applied to each
frame.  The Euclidean class is most appropriate for use with scanners, or as a
first pass for projective transformations.  The projective class and
barrel/pincushion distortion correction are most appropriate for use with
cameras.  Except when capturing flat scenes, ALE does not correct perspective
changes, so movement of cameras should ideally be constrained so that no large
translations occur.


Transformation Class Options

--translation     Only adjust the position of images
--euclidean       Adjust the position and orientation of images [default]
--projective      Use projective transformations.  Best quality, but slow.



For more information on barrel distortion correction, see .


Transformation data file options


Transformations used in alignment can be loaded from, or saved to, a
transformation data file..  This can be useful when performing alignment in
several passes, or when refining rendering options.  A transformation data file
is required for barrel/pincushion distortion correction.  For more information, 
see .


--trans-load=x    Load initial transformation settings from file x
--trans-save=x    Save final transformation data in file x


Alignment following


The --follow option hints that frames tend to be more closely aligned with
adjacent frames in the sequence than with the original frame.  --identity 
indicates that frames tend to closely align with the original frame.  These hints can be
useful even when initial alignment information is loaded from a file.


--follow          Frames align closely with their predecessor.  [default]
--identity        Frames align closely with the original frame.


Match statistics


The match statistic indicates how well a transformed frame aligns with the
alignment reference image; it is used to select or reject transformations
during alignment.  After alignment of a particular frame is complete, ALE
displays the corresponding final match statistic.  If the value is close to
100%, then the frames are well aligned; very low values can indicate
misalignment; but even frames that are very well aligned typically do not
achieve 100% alignment.  For improving image quality, ALE works most
effectively when match values are lower than 100%.


Match threshold


A match threshold can be specified; no images with final match statistics
falling below this threshold will contribute to the final output.


--threshold=x     Min. match threshold; a perfect match is 100.  (0 is default)


Alignment failure


When an image fails to meet the match threshold, a transformation is still
assigned to the frame (e.g., for writing to a transformation data file).  The assigned
transformation can be either the optimal alignment found (this is default) or
the default transformation.


--fail-optimal    Frames beneath threshold are aligned optimally.  [default]
--fail-default    Frames beneath threshold keep their default alignment.


Alignment error metric exponent


The function calculated at each pixel to determine the match statistic is of
the form (a-b)x.  The exponent value x
is 2 by default.  Larger numbers give greater influence to smaller image
features.


--metric=x        Set the alignment error metric exponent.       (2 is default)


Alignment Channel Options


In calculating the per-pixel error metric, there are three ways in which ALE
can handle color channels.  By default, ALE adds the channels before
calculating the match, but it can also be configured to rely solely on the
green color channel, or to use all three channels separately.


--align-all       Align images using all color channels
--align-green     Align images using the green channel
--align-sum       Align images using a sum of channels [default]


Monte Carlo Alignment


As aligning large images can take a long time if all pixels are examined, it
is often desirable to examine a smaller subset of pixels.  The Monte Carlo
alignment option samples a subset of pixels, specified as a percentage of the
total pixel count, with smaller numbers providing faster, but less precise,
alignment.  For defaults, see .


--mc <x>          Align using, on average, x% of available pixels (0 < x < 100)
--no-mc           Align using all pixels.


Alignment weight map


Typically, measured differences at each pixel in the alignment reference
image contribute equally to the match statistic.  To weight pixels differently,
a weight map can be used.  The scale of the map should correspond with that of
the alignment reference image, and if the upper-left corner of the map does not
coincide with the upper-left corner of the first frame in the sequence, then a
non-zero offset should be specified to indicate the difference.  See also .


--wm <f> <x> <y>  Use weight map image <f> at offset (<x>, <y>)


Frequency weighting


If ALE is compiled with FFTW support, then a high-pass-filtered version of
the alignment reference image can be used to weight reference image pixels'
contributions to the match statistic.  Frequency limiting can occur as a
fraction of the highest horizontal frequency, the highest vertical frequency,
or the highest average frequency.  Limit values should range between 0 (pass
all) and 1 (pass none).  If any limit is assigned a value of 1, no alignment
will occur, since all frequencies will have been excluded.  An output file can
optionally be specified for high-pass filtered data.


--fl <h> <v> <a>  High-pass filters: horizontal <h>, vertical <v>, average <a>.
--flshow <o>      Write high-pass filtered data to file <o>.


Certainty weighting


Certainty weighting causes contributions to alignment error to be weighted
by certainty values.


--cw              Weight alignment error by certainty.
--no-cw           Don't weight alignment error by certainty. [default]


Algorithmic weighting


This option writes the current alignment reference image and definition map
to specified files, executes a specified program with these arguments, and then
reads back alignment weights.  This option requires POSIX libraries, and
requires that ALE have been built with POSIX support enabled.


--wmx <e> <r> <d> Write reference <r>, definition <d>, execute `<e> <f> <d>`,
                  read weights <r> back.


Perturbation


The perturbation size determines the magnitude by which alignment parameters
are changed.  The size is initially set to be large, allowing large changes in
alignment to be evaluated, and is reduced as the locally optimal alignment is
found for each size.  When this size drops below a specified lower bound, the
frame is considered to be aligned.


Perturbation bounds


These options determine the upper and lower bounds for perturbation size.  The
perturb-upper and perturb-lower bounds apply to rotation (in arclength),
translation (in pixels), and the movement of the boundaries of a projected
frame (in pixels).  By appending the '%' character, values may optionally be
specified as a percentage of the number of pixels in the smallest image
dimension.  The rot-upper bound disables rotational perturbation above a
certain perturbation size (in degrees).  To disable alignment, set
perturb-upper to zero.


--perturb-upper=x Perturbation upper bound pixels/arclength    (14% is default)
                     ('x%' uses a fraction of the smallest image dimension.)
--perturb-lower=x Perturbation lower bound pixels/arclength   (.125 is default)
                     ('x%' uses a fraction of the smallest image dimension.)
--rot-upper=x     Rotation-specific upper bound in degrees    (32.0 is default)


Barrel/pincushion distortion adjustment multiplier and rate


When using barrel/pincushion distortion parameters, any frame-to-frame
adjustments to these parameters are made in a manner dependent on the
perturbation size.  A multiplier, the barrel distortion adjustment multiplier,
is used to determine the perturbation of these parameters, based on the generic
perturbation size.  Additionally, the frame-to-frame rate of change of each
barrel distortion parameter can be limited to a specified maximum.  To disable
frame-to-frame adjustment of barrel/pincushion distortion parameters, set
bda-mult to zero.  Setting bda-rate to zero disables rate limitation.


--bda-mult=x      Barrel distortion adjustment multiplier   (0.0001 is default)
--bda-rate=x      Barrel distortion rate of change maximum  (0.0004 is default)


Level of detail


Alignment at large perturbation sizes is usually carried out on
reduced-detail images.  To disable this, set lod-max to
log2(perturb-upper).


--lod-max=x       LOD scale factor is max(1, (2^floor(x))/perturb)  (1 is def.)


Perturbation Types (experimental)


Perturbations are normally performed in output image coordinates.  To perform
perturbations in source image coordinates, specify --perturb-source.


--perturb-output  Apply perturbations in output image coordinates. [default]
--perturb-source  Apply perturbations in source image coordinates.


Global Searching


In cases where important image features do not have sufficient overlap using
default alignment parameters (determined by --identity and
--follow), a number of translations can be applied to the default
parameters in order to find a new alignment starting point.  Since this process
searches the entire region of the alignment reference image, it is called a
global (as opposed to local) search.  To avoid misalignment, a minimum overlap
area can be specified.  In versions 0.8.1 and later, the search type 'points'
searches for a control point metric minimum.


--gs <type>       Set global search to <type>, one of:
                     local     Local alignment only [default]
                     inner     Alignment reference image inner region
                     outer     Alignment reference image outer region
                     all       Union of inner and outer
                     central   inner if below threshold or better; else, outer.
		     points    Align by control points.  Ignores gs-mo.   [0.8.1 and later]

--gs-mo <x>       Set <x> pixel min. overlap for global search. (16 is default)

File Output


File output options determine the format in which rendered images are written,
and how frequently they are written.  Depending on the compilation options used,
available file output options vary.


Output Color Depth


Output color depth of 8 or 16 bits of precision per color channel can be specified,
for 24-bit or 48-bit color, respectively. 
 

--8bpc            Write 8 bit per channel output [default]
--16bpc           Write 16 bit per channel output



Extension-based file type determination


If ALE has been built with ImageMagick support, then the output file type can
be determined automatically by file extension.  This is the default behavior
for ImageMagick builds.  The --auto flag explicitly specifies that
the default behavior should be used; it generates an error on builds compiled
without ImageMagick support. 
 

--auto            Determine file type automatically



PPM Output


All builds of ALE support PPM output.  PPM can be written in plain (ASCII) or
raw (binary) format.  If ALE has been built without ImageMagick support, or if
the file type cannot be automatically determined by file extension, then raw
PPM output is used by default.


--raw             Write raw PPM output
--plain           Write plain PPM output



Incremental Output


By default, ALE writes intermediate results periodically throughout the rendering
process.  This behavior can be disabled, however, so that output is written only
after rendering is complete.


--inc             Produce incremental output.  [default]
--no-inc          Don't produce incremental output.



Undefined Values


By default, ALE colors undefined values black.  To assign nearest-neighbor colors
to undefined pixels, the --def-nn option can be used.



--def-nn <R>      Use nearest-neighbor defined values within 
                  radius <R>, zero outside.  Default radius is 0.

Control Points


Control points are used for 2D and 3D alignment, and to constrain 3D scene
models.  Control point data is loaded from a control point file.  Scripts to
generate and manipulate control point files are included in the
scripts directory of the source distribution; the file
specification is outlined in the final section below.


Loading a Control Point File


The --cpf-load= option is used to load data from a control point file.



--cpf-load=<f>    Load control point data from file <f>   [0.8.1 and later]



Control Point File Format (version 0)


The version 0 control point file format consists of a version command followed
by a sequence of control points, with one control point per line of the file.



V 0
Control Point 1
Control Point 2
Control Point 3
.
.
.




Control points can be one of three types:


Type A control points


Type A control points specify a sequence of 2D points, one for each frame,
where each point is specified as a pair of floating point numbers.  If there is
no data for a frame, then "nan" should be specified.  E.g.:



A 20  30  nan nan 10  10  10  15
A 23  22  25  25  nan nan nan nan



Type B control points


Type B control points specify a 3D coordinate.  E.g.:



B 10 30 -400
B 10 15 -425



Type C control points


Type C control points specify both 2D and 3D data.  There is a single 3D point
specified, as well as one 2D point for each frame.  The 3D point appears at the
end of the line.  E.g.:



C 20  30  nan nan 10  10  10  15  10 30 -400
C 23  22  25  25  nan nan nan nan 10 15 -425

Transformation Data Files


Transformation data files are useful when performing alignment in several
passes or refining rendering options, and are necessary for specifying
barrel/pincushion distortion parameters.  They also offer a way to manually
specify alignment when ALE cannot automatically align images.  


Multiple-pass alignment


To align images in multiple passes, load the saved results of each previous
pass, as follows:



$ ale --trans-save=a.t <first pass arguments>
$ ale --trans-load=a.t --trans-save=b.t <second pass arguments>
$ ale --trans-load=b.t --trans-save=c.t <third pass arguments>
.
.
.



Rendering option refinement


To refine rendering options using the same alignment, first save the alignment
for the first option set, and then load the saved alignment information with
each subsequent option set, setting the perturbation upper bound to zero to
prevent a new alignment pass from occurring:



$ ale --trans-save=a.t <first option set>
$ ale --trans-load=a.t --perturb-upper=0 <second option set>
$ ale --trans-load=a.t --perturb-upper=0 <third option set>
.
.
.



Alignment file syntax (version 2)


There are two varieties of alignment file syntax that are both read and written
by ALE 0.7.0.  The most basic of these is version 2.  Version 3 is slightly
more complex, and is covered in the next section.



At the highest level, version 2 transformation data files contain the following
components: (a) a version command, and (b) a sequence of transformation
commands, one for each supplemental frame.  Each line of text should contain at
most one command, between which optional comments may be interspersed.  A
transformation command can be Euclidean, projective, or default.  Euclidean and
projective commands take several arguments, including the width and height of
the supplemental frame.  Default commands take no arguments.  Commands are
outlined in more detail below.


Version command


The version 2 version command is as follows:



V 2



Euclidean commands


The structure of a Euclidean command is as follows:



E <image width> <image height> <x-offset> <y-offset> <rotation-angle>



Projective commands


Projective commands map the four corners of the supplemental frame to four
points in the rendering coordinate system:



P <image width> <image height> <top-left-x> <top-left-y> <blx> <bly> <brx> <bry> <trx> <try>



Default commands


Default commands can be explicitly written as follows:



D




Alternatively, if there are more frames than alignment commands (euclidean,
projective, or default), then the last supplemental frames in the frame
sequence will be assigned the default command.


Comments

Comments can be inserted with the following syntax:


# This comment extends to the end of this line.  I can write anything I want here.



Alignment file syntax (version 3)


Version 3 syntax is required for specifying transformations for the original
frame, and for specifying barrel/pincushion distortion parameters.  



In version 3, the first transformation command is associated with the
original frame, instead of being associated with the first supplemental frame.
Also, barrel/pincushion distortion commands can precede each projective,
Euclidean, or default command.


Version command


The version 3 version command is as follows:



V 3



Barrel/pincushion distortion command


In version 3, barrel/pincushion distortion commands are supported.  Distortion
is modeled as a transformation affecting the distance of image features from the
image center.  The distorted distance is expressed as a polynomial function of
the undistorted distance.  Zeroth and first order coefficients are fixed or
automatically determined; additional coefficients can be specified explicitly,
using the following syntax:



B <n> <coefficient 2> <coefficient 3> ... <coefficient n+1>




Barrel/pincushion distortion commands should precede the projective, Euclidean,
or default transformation command for the corresponding frame.

Overview


Purpose

This manual describes program operation and command-line usage for ALE
version .






Parameter Meta-syntax


When describing parameter syntax, the following conventions are used in this manual:




Parameter Meta-syntax


<foo>
A required parameter called foo.





[<foo>]
An optional parameter called foo.




[<foo>]*
Zero or more parameters foo.








Command-line syntax for Image Processing

The following command-line invocation can be used to process a series of
frames into an output file:

ale [<option>]* <original-frame> [<supplemental-frame>]* <output-file>


For experimental argument scope syntax, see .


Option Arguments

Default Settings

Certain basic modes of operation, emphasizing image quality, speed, or
other rendering characteristics, are established in the form of default
settings.  For more information, see:


  • 





Other options
For information about other options, see:

Image Files

ALE can be configured at compile time to use one of two different file
handlers.  Execute 'ale --version' to determine which file handler is being
used.  The table below outlines the supported formats for each file handler.



Supported image file formats

Version MessageFile Types Supported



File handler:     ImageMagick



Input and output files can be any of the formats supported by
ImageMagick.







File handler:     PPM

Input files must be PPM, and output files are written as PPM.





Note that many external programs, including ImageMagick's command line utilities, can be used to
convert between PPM and other formats.

See the README included in the source distribution for more information about
compile-time configuration of file handlers.


Usage of extended PPM syntax for specifying image metadata is outlined in .








Command-line syntax for Version Information

The following command-line invocation can be used to print version
information and build options:

ale --version

The following is sample output from this invocation:

ALE Version:      
File handler:     ImageMagick
Color data:       SINGLE
Coordinate data:  SINGLE
DFT:              FFTW3
Threads:          POSIX
Assertions:       Enabled
Optimizations:    Enabled

The first line of output indicates the program version; the remaining
lines reflect the build options selected at compile time.

For more information about build options, see the README file included in
the source distribution.





Command-line syntax for Help Output

When invoked with no arguments, or an insufficient number of file arguments,
ALE outputs a help message specifying command-line usage and available help
topics.  The following is a sample invocation:

ale

Help Topics

More information about specific help topics can be obtained with an invocation
of the following form:

ale <help option>

Available help options, and their corresponding help topics, are outlined
below:

--hu              Usage (this message).
--hq              Default settings.
--hf              Image files.
--he              Exclusion regions.
--ha              Alignment (not exposure-related).
--hr              Rendering (not exposure-related).
--hx              Exposure.
--ht              Transformation data files.
--hc              Control points.
--hl              Filtering (PSFs, rendering chains).
--hd              Devices.
--hi              User Interfaces.
--hp              Process details.
--hs              Argument scope (Experimental).
--hv              Video stream processing (Experimental).
--h3              3D Modeling (Experimental).
--hz              Undocumented options.
--hA              Concatenate all help pages.

# DOCBOOK_OUTPUT_FORMATS is the default set of targets (output
# formats) that get built when you type "make" without any targets
# explicitly specified. To generate a different set of output
# formats, change the value of DOCBOOK_OUTPUT_FORMATS here or set
# it in your environment; for example:
#
#   set DOCBOOK_OUTPUT_FORMATS="html pdf"; export DOCBOOK_OUTPUT_FORMATS
#
# Of course by explicitly specifying particular targets when you
# invoke "make", you can always override generation of the default
# set of targets; for example:
#
#   make html txt
#
# That would generate just HTML (unchunked) and plain-text output.
#
DOCBOOK_OUTPUT_FORMATS ?= man chunk txt pdf info

# If you want XHTML output instead of HTML, set HTML_OR_XHTML to
# 'xhtml' or just specify 'xhtml" in DOCBOOK_OUTPUT_FORMATS.

# for FO output

#
# NOTE: The following changes may be required to the stock docbook stylesheets
# for double-sided output:
#
# In /usr/share/xml/docbook/stylesheet/nwalsh/fo:
#
# 	o Add '0pc'
#	  to the template 'footer.table'.  This fixes number positioning in
#	  double-sided output.
#	o In the test for generating 'section.head.marker', change
#	  the test '$double-sided != 0' to read '$double-sided > 1'.
#	  This disables section-name headings in favor of chapter-name
#	  headings.

    Tutorial
  

Introduction

Purpose (foobar)

This page summarizes program operation and command-line usage for ALE
versions 0.8.0 through 0.8.4.  Features specific to a particular version
are annotated (e.g.  [ALE 0.8.1 and later]).

Manual pages linked from this section describe default
settings, file output, alignment, rendering, exclusion regions, control points, user interfaces, devices, and 3D scene reconstruction.

For more information on ALE, see the ALE Home Page.




Parameter Meta-syntax





<foo>
A required parameter called foo.




[<foo>]
An optional parameter called foo.




[<foo>]*
Zero or more parameters foo.








Command-line syntax for Image Processing

The following command-line invocation can be used to process a series of
frames into an output file:


ale [<option>]* <original-frame> [<supplemental-frame>]* <output-file>



Option Arguments


Certain basic modes of operation, emphasizing image quality, speed, or other
rendering characteristics, are now established in the form of default settings.

Other options are outlined in the manual pages describing file output, rendering, alignment, exclusion
regions, devices, user interfaces,
and 3D scene reconstruction.


Image Files


ALE can be configured at compile time to use one of two different file
handlers.  Execute 'ale --version' to determine which file handler is being
used.  The table below outlines the supported formats for each file handler.








Version MessageFile Types Supported




File handler:     ImageMagick




Input and output files can be any of the formats supported by
ImageMagick.






File handler:     PPM


Input files must be PPM, and output files are written as PPM.








Note that many external programs, including ImageMagick's command line utilities, can be used to
convert between PPM and other formats.

See the README included in the source distribution of ALE for more information about
compile-time configuration of file handlers.





Command-line syntax for Version Information

The following command-line invocation can be used to print version
information and build options:


ale --version


The following is sample output from this invocation:


ALE Version:      0.8.4
File handler:     ImageMagick
Color data:       SINGLE
Coordinate data:  SINGLE
DFT:              FFTW3
Assertions:       Enabled
Optimizations:    Enabled



The first line of output indicates the version of ALE source code being
used; the remaining lines reflect the build options selected at compile
time.

For more information about build options, see the README file included in
the ALE source distribution.





Command-line syntax for Help Output

When invoked with no arguments, or an insufficient number of file arguments,
ALE outputs a help message specifying command-line usage and available help
topics.  The following is a sample invocation:


ale



Help Topics


More information about specific help topics can be obtained with an invocation
of the following form:


ale <help option>


Available help options, and their corresponding help topics, are outlined
below:


--hu              Usage.
--hq              Default settings.
--hf              Image files.
--he              Exclusion regions.
--ha              Alignment (not exposure-related).
--hr              Rendering (not exposure-related).
--hx              Exposure.
--ht              Transformation data files.
--hc              Control points.  [0.8.1 and later]
--hl              Filtering (PSFs, rendering chains).
--hd              Devices.
--hi              User Interfaces.
--hv              Video stream processing (Experimental).
--h3              3D Modeling.
--hz              Undocumented options.
--hA              Concatenate all help pages.

# This script attempts to calibrate a filter under ALE for characteristics of a
# specific device.  It uses the stdin IPC device to configure the filter.
#
# The initial filter tested is the box filter, and individual elements
# of the filter are increased or decreased to determine the effects of
# such changes.  When the change increases the match with the desired
# output, it is kept.  Otherwise, the change is backed out.
#
# The magnitude of change tested is determined by an increment variable,
# which starts at a user-defined value and is halved until it is smaller
# than 0.1 (an arbitrary value which could easily be changed).
#
# For every increment value, all elements are tested with positive and negative
# changes of this magnitude.  If an element fails to offer any error
# improvement on a given pass, it is skipped on all future passes for the same
# increment value.
#
# Passes at a given increment value continue until all elements are skipped, at
# which point the magnitude is halved.
#
# It may be a good idea to use this script with relatively small images, as
# large images may require a long time to process.

#
# Remove these two lines to run the script.
#
# Note: This script has been manually updated for ALE 0.7.0 from a non-generic
# working copy, and hence may contain serious bugs.  Bugs may be reported to

       smallest image dimension (useful for large images?).
     o Fixes bugs in exclusion region handlers.
     o Fixes bugs in alignment failure handlers.
     o Avoids superfluously large undefined regions.
     o Adds experimental options for refining perturbation.

23. Version 0.7.1, 2004-Aug-27

   This release fixes alignment bugs, adds a global search option, and adds
   support for the OmniView OV7620 sensor. (Freshmeat announcement)

  23.1. Mailing list announcement

     o Add linear PSF for OV7620
     o Add option to concatenate help pages
     o Fix VISP segfault
     o Incorporate changes from 0.7.0-patch1

  23.2. Notes

   The default PSF for the OV7620 can be a bit noisy. As an alternative,
   box=1.3+box=1.8 also works well in some cases, and is less noisy.

22. Version 0.7.0-patch1, 2004-Aug-22

  22.1. Mailing list announcement

     o Fixes alignment bugs.
     o Adds a global search option.
     o Adds support for ov7620 in raw, linear mode.

  22.2. Notes

   The ov7620 device option expects that the 7620 be in raw, linear mode, and
   that clamping be turned on. These features may not be accessible using
   standard drivers.

21. Version 0.7.0, 2004-Aug-06

   This release updates the renderer to support a variety of filters,
   including sinc and Lanczos, and adds new options for excluding image
   regions and processing video frames. (Freshmeat announcement)

20. Version 0.6.0, 2004-Feb-10

   Merging and drizzling renderers now operate in linear colorspace, and the
   Irani-Peleg renderer has been extended to handle convolutions in both
   linear colorspace (e.g. lens blur) and non-linear colorspace (e.g. some
   types of in-camera sharpening). New options in this release include
   certainty weighting and exposure registration. (Freshmeat announcement)

19. Version 0.5.1, 2003-Nov-19

   Changes in this release include optional support for 16-bit color channels
   and built-in support for all PPM file types. Also, a user manual and an
   updated technical description are now available. (Freshmeat announcement)

   [This release was, and remains (as of Sep 2006), the most advanced version
   storing pixels as integer values (rather than as floating-point values).
   As integer values may be more suitable for certain applications,
   integer-valued functions may be re-introduced, possibly as library code,
   in the future. 19-Sep-2006]

  19.1. Program summary

   This release includes a revised summary:

   ALE is a program that can render high-fidelity images of real scenes by
   aligning and combining many similar images from a camera or scanner. The
   correct similarity between images is roughly that achieved by a somewhat
   unsteady hand holding a camera.

18. Version 0.5.0, 2003-Nov-02

   Alignment following has been modified to support multiple-pass alignment
   of panoramic image mosaics. Other changes in this release include code
   cleanup and documentation updates. (Freshmeat announcement via Neohapsis)

17. Version 0.4.8, 2003-Aug-01

   The Monte Carlo alignment algorithm has been modified, and may now offer
   better alignment for small sample sizes. Also, the Irani-Peleg renderer
   now writes output after each iteration when incremental output is enabled.
   Other changes include a bugfix in Euclidean alignment, a new option for
   configuring the level of detail, and a new independent constraint for
   rotational perturbation. (Freshmeat announcement via Neohapsis)

16. Version 0.4.7, 2003-Jul-27

   Support for device-specific projection functions and various bugfixes have
   been added to the Irani-Peleg renderer. Also, a new option has been added
   that may be useful for video stabilization applications. (Freshmeat
   announcement via Neohapsis)

15. Version 0.4.6, 2003-Jul-01

   This release fixes bugs in drizzling and post-processing. The following
   combinations should now work as expected: drizzling in combination with
   scaling and Irani-Peleg image reconstruction in combination with
   high-frequency enhancement. (Freshmeat announcement via Neohapsis)

14. Version 0.4.5, 2003-Jun-23

   This release resolves a number of minor alignment bugs. (Freshmeat
   announcement via Neohapsis)

13. Version 0.4.4, 2003-Jun-06

   The PPM file handler has been updated to open files in binary mode,
   resolving a serious bug under Windows. Also, the percentage of pixels used
   in Monte Carlo alignment now more closely matches user specifications in
   typical cases. (Freshmeat announcement via Neohapsis)

12. Version 0.4.3, 2003-May-30

   A Monte Carlo alignment option has been added, which may reduce alignment
   time. An option to disable incremental file output has also been added.
   (Freshmeat announcement via Neohapsis)

11. Version 0.4.2, 2003-May-23

   An iterative image reconstruction renderer has been added, and the PPM
   file handler has been updated to correctly handle PPM header comments.
   (Freshmeat announcement via Neohapsis)

10. Version 0.4.1, 2003-Apr-28

   Increased spatial extents, drizzling, and new alignment options have been
   added in this release. (Freshmeat announcement via Neohapsis)

9. Version 0.4.0p1, 2003-Apr-04

   A bugfix from the Debian ALE package version 0.4.0-1 has been merged.
   Without this fix, an assertion failure can occur when ImageMagick support
   is enabled. (Freshmeat announcement via Neohapsis)

     o The original Debian fix was implemented by Debian package maintainer
       Nick Rusnov.

8. Version 0.4.0, 2003-Mar-30

   A general scaling option has been added, and the high-frequency
   enhancement filter now works near image boundaries. (Freshmeat
   announcement via Neohapsis)

7. Version 0.3.2, 2003-Mar-26

   A match summary was added to the program's output, comments in
   transformation file output were made more helpful, and an experimental
   high-frequency enhancement option was added. (Freshmeat announcement via
   Neohapsis)

6. Version 0.3.1, 2003-Mar-25

   (This release appears to have been superseded by 0.3.2.)

5. Version 0.3.0, 2003-Jan-17

   New options in this release facilitate writing final alignment
   transformations to a file, reading initial alignment transformations from
   a file, and setting an upper boundary on the correction step size used in
   alignment. (Freshmeat announcement via Neohapsis)

4. Version 0.2.0, 2003-Jan-01

   General projective transformations can now be used in image alignment.
   (Freshmeat announcement via Neohapsis)

3. Version 0.1.2, 2002-Dec-13

   A new file handler has been added to read and write JPEG, PNG, and other
   image formats using the ImageMagick C API. The default PPM-only file
   handler now deals with certain file errors more gracefully. (Freshmeat
   announcement via Neohapsis)

     o Translation of file formats using ImageMagick was suggested by Nick
       Rusnov.

2. Version 0.1.1, 2002-Dec-09

   In this version, a scaling bug that caused corruption of boundary pixels
   has been fixed. Also, the alignment algorithm has been modified to use
   reduced detail for coarse alignment steps. (Freshmeat announcement via
   Neohapsis)

1. Version 0.1.0, 2002-Nov-26

   The image alignment algorithm has been updated. (Freshmeat announcement
   via Neohapsis)

0. Version 0.0.0, 2002-Oct-11

   Initial release

  0.1. Program summary

   ALE aligns and merges several similar images from a digitizing device
   (such as a digital camera or scanner) into a single image. This may have
   the effect of producing a relatively alias-free image (sometimes called
   "anti-aliasing").

   Abstract

   This article includes download, build, and installation instructions.

     ----------------------------------------------------------------------

   1. Compiling from source

                1.1. URLs

                1.2. Build prerequisites

                1.3. Extraction

                1.4. Running configure

                1.5. Configuration options

                1.6. Cross-compilation

                1.7. Further details

   2. On-line resources

                2.1. Mailing list

1.  Compiling from source

  1.1.  URLs

     o http://auricle.dyndns.org/ALE/download/ale-0.9.0.3.tar.gz

  1.2.  Build prerequisites

    1.2.1.  GCC C++ compiler

   GCC version 3.2.3 with C++ support is known to build ALE successfully.
   Older versions of GCC may fail to compile some versions of ALE.

    1.2.2.  Prerequisites for building on Windows

   Successfully running the configuration script on Windows (e.g., for native
   builds) may require installation of Cygwin. For more information on
   Cygwin, see:

     o http://www.cygwin.com/

   Alternatively, this package can be cross-compiled for Windows on a
   non-Windows architecture, provided that the appropriate cross-compilers
   and libraries are available.

  1.3.  Extraction

   Download the source archive file from the URL indicated in the section
   'URLs', and invoke:

 tar xzf ale-0.9.0.3.tar.gz
 cd ale-0.9.0.3

   Invoking 'ls configure' afterward should reveal an executable script
   'configure'. This script is used to determine the capabilities of the
   system that will run the software.

  1.4.  Running configure

   This package uses a configuration script, 'configure', generated by the
   GNU project build tools ("autotools"). For most cases, it should be
   sufficient to invoke:

 ./configure
 make
 make install

   In cases where the defaults are not adequate, configuration options can be
   passed to the configuration script.

  1.5.  Configuration options

   Configuration options can be passed to the 'configure' script prior to
   build and installation, as:

 ./configure --config-option1 --config-option2 ...
 make
 make install

   Options specific to this package are described in the following
   subsections. General configuration options are described in the file
   'INSTALL' included in the source package.

    1.5.1.  ImageMagick Support

   Enabling ImageMagick support allows ALE to make use of the file-handling
   capabilities of ImageMagick ( http://imagemagick.org/ ). This includes
   reading and writing a variety of file formats, including, among many
   others, PNG and JPEG (two formats commonly used in web publishing) as well
   as common interchange formats such as PPM and TIFF. ImageMagick 6.0.6 is
   known to work with this version of ALE; certain older versions of
   ImageMagick may cause compile, link, or runtime errors. By default,
   support is automatically detected.

 --with-imagemagick=auto  Auto-detect ImageMagick support [default]
 --with-imagemagick=yes   Enable ImageMagick support
 --with-imagemagick=no    Disable ImageMagick support

    1.5.2.  Color Data Precision

   ALE's internal data structures store each color channel within a pixel as
   floating-point data; similarly, arithmetic operations on color channels
   are performed in floating point. The available data-type configurations
   are listed below, with typical data sizes indicated in parentheses.

 --with-colors=single   Use C++ 'float' data type (32-bit)  [default]
 --with-colors=double   Use C++ 'double' data type (64-bit)

    1.5.3.  Coordinate Data Precision

   In general, coordinate transformations used by ALE produce results outside
   of the set of integers; hence, coordinates are treated as floating-point
   data. The two available data-type configurations are listed below, with
   typical data sizes indicated in parentheses.

 --with-coords=single   Use C++ 'float' data type (32-bit)  [default]
 --with-coords=double   Use C++ 'double' data type (64-bit)

    1.5.4.  Thread support

   Threads can improve performance on multiprocessor machines. POSIX threads
   are currently supported.

 --enable-threads=auto  Auto-detect thread support.  [default]
 --enable-threads=yes   Enable thread support.
 --enable-threads=no    Disable thread support.

    1.5.5.  FFTW Support

   This feature is required in order to use the --fl option; it also
   determines the approach to calculation of discrete Fourier transforms used
   by the Irani-Peleg renderer. For more information on FFTW, see
   http://fftw.org/.

 --with-fftw3=auto      Auto-detect FFTW3.  [default]
 --with-fftw3=yes       Use FFTW3 discrete Fourier transform.
 --with-fftw3=no        Use built-in discrete Fourier transform.

    1.5.6.  Enable --wmx

   This build option is required in order to use the --wmx option. If
   --enable-wmx is specified, it is expected that fork() and execlp() calls
   are available.

 --enable-wmx=auto      Automatically detect whether to enable --wmx
 --enable-wmx=yes       Enable --wmx
 --enable-wmx=no        Do not enable --wmx

    1.5.7.  Getsize

   This build option is required to obtain additional output from --ui=tty.
   If TIOCGWINSZ is not defined in , however, additional output
   will not be provided even if --enable-getsize is specified at build time.

 --enable-getsize=auto   Check for TIOCGWINSZ at build time.  [default]
 --enable-getsize=yes    Configure to attempt to use TIOCGWINSZ
 --enable-getsize=no     Do not attempt to use TIOCGWINSZ

    1.5.8.  Assertions

   Finding bugs within ALE, or within custom modifications to ALE, can be
   simplified by enabling run-time assertions. These checks enforce
   conditions believed to be necessary or desirable for correct program
   operation. If a condition is not satisfied, ALE will abort and display a
   message indicating the failed assertion.

 --enable-assertions    Enable assertions.  [default]
 --disable-assertions   Disable assertions.

  1.6.  Cross-compilation

   For cross-compilation, it may be necessary to specify both host and build
   machine types, using the configure --host and --build options. For more
   information on these options, see the file 'INSTALL' in the source
   package.

  1.7.  Further details

   General operation of the configure script is described in more detail in
   the file 'INSTALL' in the source package.

/* Usage suggestions:

   Programs that use  should be aware of some limitations
   and standards compliance issues.

   Standards compliance:

       -  must be #included before 'bool', 'false', 'true'
         can be used.

       - You cannot assume that sizeof (bool) == 1.

       - Programs should not undefine the macros bool, true, and false,
         as C99 lists that as an "obsolescent feature".

   Limitations of this substitute, when used in a C89 environment:

       -  must be #included before the '_Bool' type can be used.

       - You cannot assume that _Bool is a typedef; it might be a macro.

       - Bit-fields of type 'bool' are not supported.  Portable code
         should use 'unsigned int foo : 1;' rather than 'bool foo : 1;'.

       - In C99, casts and automatic conversions to '_Bool' or 'bool' are
         performed in such a way that every nonzero value gets converted
         to 'true', and zero gets converted to 'false'.  This doesn't work
         with this substitute.  With this substitute, only the values 0 and 1
         give the expected result when converted to _Bool' or 'bool'.

   Also, it is suggested that programs use 'bool' rather than '_Bool';
   this isn't required, but 'bool' is more common.  */

   this, values of type '_Bool' may promote to 'int' or 'unsigned int'
   (see ISO C 99 6.7.2.2.(4)); however, '_Bool' must promote to 'int'

\`configure' configures ALE 0.9.0.3 to adapt to many kinds of systems.

Usage: $0 [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
  -h, --help              display this help and exit
      --help=short        display options specific to this package
      --help=recursive    display the short help of all the included packages
  -V, --version           display version information and exit
  -q, --quiet, --silent   do not print \`checking...' messages
      --cache-file=FILE   cache test results in FILE [disabled]
  -C, --config-cache      alias for \`--cache-file=config.cache'
  -n, --no-create         do not create output files
      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

Installation directories:
  --prefix=PREFIX         install architecture-independent files in PREFIX
                          [$ac_default_prefix]
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                          [PREFIX]

By default, \`make install' will install all the files in
\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
an installation prefix other than \`$ac_default_prefix' using \`--prefix',
for instance \`--prefix=\$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR            user executables [EPREFIX/bin]
  --sbindir=DIR           system admin executables [EPREFIX/sbin]
  --libexecdir=DIR        program executables [EPREFIX/libexec]
  --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
  --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]
  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
  --libdir=DIR            object code libraries [EPREFIX/lib]
  --includedir=DIR        C header files [PREFIX/include]
  --oldincludedir=DIR     C header files for non-gcc [/usr/include]
  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
  --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]
  --infodir=DIR           info documentation [DATAROOTDIR/info]
  --localedir=DIR         locale-dependent data [DATAROOTDIR/locale]
  --mandir=DIR            man documentation [DATAROOTDIR/man]
  --docdir=DIR            documentation root [DATAROOTDIR/doc/ale]
  --htmldir=DIR           html documentation [DOCDIR]
  --dvidir=DIR            dvi documentation [DOCDIR]
  --pdfdir=DIR            pdf documentation [DOCDIR]
  --psdir=DIR             ps documentation [DOCDIR]

Program names:
  --program-prefix=PREFIX            prepend PREFIX to installed program names
  --program-suffix=SUFFIX            append SUFFIX to installed program names
  --program-transform-name=PROGRAM   run sed PROGRAM on installed program names

System types:
  --build=BUILD     configure for building on BUILD [guessed]
  --host=HOST       cross-compile to build programs to run on HOST [BUILD]

Optional Features:
  --disable-option-checking  ignore unrecognized --enable/--with options
  --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
  --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
  --disable-dependency-tracking  speeds up one-time build
  --enable-dependency-tracking   do not reject slow dependency extractors
  --enable-shared[=PKGS]  build shared libraries [default=yes]
  --enable-static[=PKGS]  build static libraries [default=yes]
  --enable-fast-install[=PKGS]
                          optimize for fast installation [default=yes]
  --disable-libtool-lock  avoid locking (might break parallel builds)
  --enable-threads        enable multithreading: auto, no, yes (default=auto)
  --enable-assertions     check runtime assertions (default=yes)
  --enable-optimizations  use optimization code (default=yes)
  --enable-getsize        get terminal size: auto,no,yes (default=auto)
                            (not doing this disables certain UI updates)
  --enable-wmx            Enable --wmx option: auto,no,yes (default=auto)
                            (this option requires execlp() and fork())

Optional Packages:
  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
  --with-pic              try to use only PIC/non-PIC objects [default=use
                          both]
  --with-gnu-ld           assume the C compiler uses GNU ld [default=no]
  --with-imagemagick      ImageMagick file handling: auto,no,yes (default=auto)
  --with-fftw3            FFTW3 fourier transforms: auto,no,yes (default=auto)
  --with-colors=TYPE      use TYPE colors: single,double,fixed32,fixed16 (default=single)
  --with-coords=TYPE      use TYPE coords: single,double,fixed32,fixed16 (default=single)
  --with-hashmap=TYPE     Use TYPE hash map: no,gnu,std (default=no)

Some influential environment variables:
  CXX         C++ compiler command
  CXXFLAGS    C++ compiler flags
  LDFLAGS     linker flags, e.g. -L if you have libraries in a
              nonstandard directory 
  LIBS        libraries to pass to the linker, e.g. -l
  CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I if
              you have headers in a nonstandard directory 
  CC          C compiler command
  CFLAGS      C compiler flags
  CPP         C preprocessor
  CXXCPP      C++ preprocessor

Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.

	      http://lists.gnu.org/archive/html/bug-coreutils/2005-10/msg00086.html
	      This test is not quite right, since xlc is allowed to
	      reject this program, as the initializer for xlcbug is
	      not one of the forms that C requires support for.
	      However, doing the test right would require a run-time
	      test, and that would make cross-compilation harder.
	      Let us hope that IBM fixes the xlc bug, and also adds
	      support for this kind of constant expression.  In the
	      meantime, this test will reject xlc, which is OK, since
	      our stdbool.h substitute should suffice.  We also test
	      this with GCC, where it should work, to detect more
	      quickly whether someone messes up the test in the
	      future.  */

# libraries is broken (non-POSIX).

# Create a list of thread flags to try.  Items starting with a "-" are
# C compiler flags, and other items are library names, except for "none"
# which indicates that we try without any flags at all, and "pthread-config"
# which is a program returning the flags for the Pth emulation library.

# individual items follow:

# pthreads: AIX (must check this before -lpthread)
# none: in case threads are in libc; should be tried before -Kthread and
#       other compiler flags to prevent continual compiler warnings
# -Kthread: Sequent (threads in libc, but -Kthread needed for pthread.h)
# -kthread: FreeBSD kernel threads (preferred to -pthread since SMP-able)
# lthread: LinuxThreads port on FreeBSD (also preferred to -pthread)
# -pthread: Linux/gcc (kernel threads), BSD/gcc (userland threads)
# -pthreads: Solaris/gcc
# -mthreads: Mingw32/gcc, Lynx/gcc
# -mt: Sun Workshop C (may only link SunOS threads [-lthread], but it
#      doesn't hurt to check since this sometimes defines pthreads too;
#      also defines -D_REENTRANT)
#      ... -mt is also the pthreads flag for HP/aCC
# pthread: Linux, etcetera
# --thread-safe: KAI C++
# pthread-config: use pthread-config program (for GNU Pth library)

   Abstract

   This article contains detailed change information for each release.

     ----------------------------------------------------------------------

46. Version 0.9.0.3, 2009-Mar-31

     o Revise --version to include ImageMagick library information.
     o Add ditz issue database and package document BUG-REPORTING.
     o Refine warnings for 8-bit output when --16bpc (incl. default).
     o Fix --16bpc default behavior.
     o Fixed serious memory leak in alignment code, and less serious leaks.

45. Version 0.9.0.2, 2008-Nov-05

  45.1.  Documentation

     o Update documentation makefile for better links compatibility.

  45.2.  Scripts

     o Fix 'exec -a' bashism in ale script, after this was reported by Mihai
       Varzaru as being broken in Ubuntu 8.10.

44. Version 0.9.0.1, 2008-Jun-13

     o Use a pager (e.g., less) when displaying help.
     o Add a man page, at the recommendation of Debian developer Ruben
       Molina. The man page structure roughly follows that of Debian
       Iceweasel, GNU tar, and the earlier ALE manual page for Debian by Nick
       Rusnov and Ruben Molina.
     o Add new algorithms for pixel assignment in multi-alignment, including
       filling, least-size local selection, and global-best selection.
     o Fix various multi-alignment bugs, including a bug causing increased
       computational complexity for rendering, as well as offset and scaling
       bugs.
     o Modify --lod-max to --lod-preferred, add a dimension restriction
       --min-dimension on level-of-detail, and make --lod-preferred=-3 and
       --min-dimension=10 default.
     o Revise DejaGNU test suite for current option syntax, so that "make
       check" now runs all tests.
     o Do not attempt to handle --trans-{save,load} arguments as images in
       the ale wrapper script.
     o Add include  to ui/ui.h in an attempt to resolve Debian bug
       #482765, reported by Marc Brockschmidt and noted by Ruben Molina.
     o Include more information about scale cluster structures in the logging
       ui.
     o Add tonal registration by element to multi-alignment code.
     o Add a minimum average certainty for registration of multi-alignment
       elements.
     o Modify ale script to tally thread statistics when the environment
       variable ALE_COUNT_THREADS is set non-zero.

43. Version 0.9.0, 2008-Apr-14

     o Add skeletal web documentation to the documentation tree, in doc/web,
       and revise this to consolidate more information on the front page.
     o Implement an alignment technique allowing multiple alignments for a
       single frame. Handling parts of a frame separately to resolve
       alignment issues (but using match thresholding to discard regions
       instead of using multiple alignments) was suggested by Rob Stewart.
     o Add --resident parameter, allowing explicit allocation of backing
       store for (e.g., large) image data structures.
     o Check for NaN in linearization and unlinearization in
       exposure_default, as a possible fix for a segmentation fault reported
       by Bret Towe.

42. Version 0.8.11, 2007-Nov-03

     o Revise certain code for improved execution speed, including disabling
       certain assertions and reducing calls to pow().
     o Replace geometric-mean filtering of weight values with minimum-value
       filtering, reducing calls to pow().
     o Add fixed-point data types selectable at configuration time for
       coordinate and color data, hence improving speed on certain embedded
       platforms. Use on phones was suggested by Wen Guihua.
     o Revise incremental rendering code to store color values unnormalized
       by weights.
     o Revise multi-alignment options for the currently-considered
       implementation.
     o Eliminate NaN propagation that could lead to alignment failure in
       certain cases, perhaps causing an alignment bug reported in earlier
       versions by Gregory Maxwell.

41. Version 0.8.10.1, 2007-Oct-04

     o Change 'char *' referencing string literals to 'const char *'.
     o Set perturbation multipliers to 1 in cases of a non-finite value.

40. Version 0.8.10, 2007-Oct-02

     o Add threading for d2::image::*scale_by_half() functions.
     o Always rescale transformations for full detail after alignment is
       complete.
     o Make --lod-max=-4 default.
     o Make default --dchain auto:triangle:2,fine:box:1,triangle:2, which
       should produce better output during re-filtering than the previous
       default.
     o Revise re-filtering operation to use as a filter scale the distance
       between nearest defined points in opposite axis-centered cones about
       the point to be filtered.
     o Update scale cluster structures and interpolation routines used in
       alignment for calculating and storing certainty and weights; in
       particular, certainty of the input frame is now pre-calculated for
       multiple levels of detail.
     o Add currently-unused skeletal code for non-linear level of detail
       calculations.
     o Revise Monte-carlo value to use a single static default, removing
       dynamic behavior and certain associated support code, and applying the
       sampling rate in a uniform manner to all levels of detail and all
       tonal and spatial registration algorithms.
     o Fix error in level-of-detail accounting in alignment code.
     o Replace references to math.h with references to ale_math.h.

39. Version 0.8.9.1, 2007-Aug-31

     o Attempt to resolve certain 'always true' warnings reported by Marius
       Schamschula on Mac OS 10.3.9 (PPC).
     o Add macros for isinf() and isnan() in an attempt to resolve build
       failures reported by Marius Schamschula on Mac OS 10.3.9 (PPC).
     o Resolve certain build errors occuring when configuring
       --disable-threads, or when threads are unavailable.
     o Remove instrumentation writing to 'lsimulated.png'.

38. Version 0.8.9, 2007-Aug-25

     o Set new defaults for --ips, --dchain, and --3d-dchain, and remove --q*
     o Add rendering chain scaled sampling filter type auto:, implementing
       re-filtering, with rough automatic filter size determination.
     o Add an abstract domain decomposition threading class.
     o Revise Irani-Peleg code for reduced memory and cpu use.
     o Attempt to fix exclusion region handling after a bug report by Gregory
       Maxwell; other issues may remain.
     o Fix handling of --ip-{mean,median}, resolving a bug noted by Gregory
       Maxwell.
     o Add wrapper script 'ale' for handling raw files and extracting Exif
       metadata.
     o Allow any match when the threshold specified is neither positive nor
       zero.
     o Update license to GPLv3.
     o Various rendering bugfixes.

37. Version 0.8.8.1, 2007-May-18

  37.1.  Build

     o Disable d2::gauss::cutoff definition after a build failure reported by
       Marius Schamschula on an Intel Mac running 10.4.9 (gcc 4.0.0?).

36. Version 0.8.8, 2007-May-15

     o Include an incomplete implementation for multiple alignment region
       handling.
     o Make --16bpc default.
     o Add extents calculation to d2::render::ipc to limit the area examined
       during exposure re-estimation.
     o Provide a new cache of fixed size for input images, defaulting to
       256MB, adjustable via the --cache option.
     o Add error statistics for calculating center of rotation and
       perturbation size for alignment.
     o Add loop avoidance for dynamic monte carlo alignment.
     o Reduce --mcd-removal default to 10.
     o Use synchronized instead of unsynchronized dynamic monte carlo removal
       checks.
     o Disable --follow in the non-default case when perturbation size is
       zero.
     o Make --no-inc default.
     o Add 'defaults' global search option, and make this option default.
     o Modify --gs-mo to allow specification as a percentage, and make 67%
       default.
     o Add user interface options --ui=log and --ui=quiet, with greater and
       lesser verbosity, respectively.
     o Modify black level handling to always use linear values.
     o Increase default barrel distortion multiplier and rate maximum to 2.0
       and 8.0, respectively.
     o Revise ordering of ui_tty status output so that more informative
       fields occur earlier in the string.
     o Modify numerical formatting of certain UI elements to preserve
       constancy of field locations in typical cases.
     o Add Gaussian PSF. (HJ Hornbeck)
     o Recalculate diff statistics after increasing the mc parameter in
       dynamic monte carlo alignment.
     o Update Nikon D50 PSF. (HJ Hornbeck)
     o Add UI update thread, in cases where threads are available.
     o Allow file-scoped --gs and --gs-mo options.
     o Ignore fex regions for nex SSFEs, resolving a bug noted by Gregory
       Maxwell.
     o Add --black option for specifying black level as a fraction of
       saturation.
     o Add --ev option for specifying ISO100-equivalent EV.
     o Add breakdown of profiling information by perturbation size for local
       alignment.

35. Version 0.8.7, 2007-Mar-04

  35.1.  Alignment

     o Modify d2::image::defined_scale_by_half() to use a geometric mean, so
       that alignment at reduced level of detail will still work at larger
       reductions when using non-zero certainty.

  35.2.  Rendering

     o Add a weight-limiting option to the Irani-Peleg renderer.
     o Add incremental renderer mean invariant avgf:: weight-limited to
       initial values.

34. Version 0.8.6, 2007-Feb-17

     o In d2::align, use rotation about the frame center as an alternative in
       cases where the sampling centroid is undefined.
     o Modify d2::point::{neg,pos}inf() assertions to allow for isinf()
       implementations returning any non-zero value for any infinity.
     o Re-adjust exposure in Irani-Peleg even when no non-linear stage is
       present.
     o Adjust the default pixel definition threshold to account for the
       certainty floor.
     o Use a rudimentary, single-pass estimate-based certainty approach for
       incremental rendering.
     o When --cx is positive, use only certainty calculated from the
       simulated scene for estimating tonal registration in Irani-Peleg
       passes.
     o Remove --qr default setting, as certainty and range-extension now have
       established general defaults.
     o Change --cx to 1 by default. Change --exp-extend to be disabled by
       default. Remove these flags from default settings.
     o Update driver names to omit file type qualifiers, according to the
       convention used in HJ Hornbeck's Nikon D50 device configuration patch.
     o Add Nikon D50 device configuration. (HJ Hornbeck)
     o Update default settings according to time and image quality test
       results. fine:triangle:2, gauss:0.75, and combinations of these
       filters were suggested by HJ Hornbeck.
     o Revise incremental renderer to store unnormalized values, for better
       handling of small weights, and eliminate the minimum contribution
       weight.
     o Add inlining and pre-calculation to Irani-Peleg. (HJ Hornbeck)
     o Add gaussian sampling filter. (HJ Hornbeck)

33. Version 0.8.5, 2007-Jan-19

  33.1.  Documentation

     o Remove binaries and documentation sections from the readme, and prune
       non-package documentation for source distributions.

  33.2.  Alignment

     o Make the --follow alignment option default.
     o Modify rotational alignment search to rotate about the centroid of the
       sample region.

  33.3.  User interfaces

     o Add help text for argument scope.

  33.4.  3D Models

     o Revert 3D code to experimental status due to poor handling of real
       image sets.
     o Modify 3D code for slightly better handling of real image sets.

32. Version 0.8.5-pre3, 2006-Nov-03

  32.1.  Alignment

     o Fix a potential nondeterminism bug due to undefined seed bits in the
       random number generator. (Fixes certain alignment failures.)
     o Add dynamic monte carlo alignment, and make this default.
     o Allow file-scoped use of --perturb-upper.

  32.2.  Rendering

     o Modify default settings using Irani-Peleg rendering to use the
       triangle:2 incremental rendering chain.

  32.3.  Exposure

     o Correct --exp-mult arg count. (Gregory Maxwell)

31. Version 0.8.5-pre2, 2006-Oct-25

  31.1.  Alignment

     o Add option --profile to measure elapsed real time for 2D alignment and
       rendering operations.
     o Add support for POSIX threads to 2D alignment and rendering code.
       (Adding multithreading support was first suggested by Jody (Joe)
       Harris. Testing of multithreaded code on multiprocessor hardware was
       done by Gregory Maxwell.)

  31.2.  Rendering

    31.2.1.  Scale

     o Modify d2::image::scale() to correctly handle offsets for scale
       factors other than negative powers of two.

  31.3.  User interfaces

     o Reformat most help text to fit a 79 column screen.

30. Version 0.8.5-pre1, 2006-Oct-16

     o Incorporate all existing ALE documentation within the source tree, and
       license under GPL. Begin migration of documentation, including package
       documentation files, to a more flexible format.
     o Modify ui_tty for correct operation under Hurd and DragonFly consoles.
     o Revise README for autotools build and installation.
     o Add file 'TODO', containing a to-do list for future releases.
     o Add AUTHORS file, in accordance with the autotools packaging
       standards.
     o Revise Changelog name to autotools-approved ChangeLog
     o Add NEWS file containing mailing list and Freshmeat announcement text
       for versions through 0.8.4. This file is required by autotools.
     o Add options --f{ex,crop} for frame-coordinate exclusion regions.
     o Add autotools-based configuration, build, and installation facilities,
       replacing the earlier Makefile-based configuration and build process.
     o Modify --mc to be a file-scoped option.
     o Modify command-line interface to accept certain scope operators, and
       to increase uniformity of syntax.
     o Move input interface details, including option handling, messages, and
       help information, to the ui/ subdirectory.
     o In d3::scene, always use filler spaces when --pc all is specified.

29. Version 0.8.4, 2006-May-14

  29.1.  Packaging

     o Fix build error noted by Gregory Maxwell and re-tag version.

  29.2.  Documentation

     o Add dates to the Changelog, using dates in comments in the download
       page on the website for versions prior to 0.8.0, and using dates from
       the darcs repository for versions 0.8.0 and later.

  29.3.  Alignment

     o Add a script 'transform' for applying an inverse projective
       transformation. Recalculation of transformations was suggested by Rob
       Stewart (ALE mailing list message, 2005-Dec-28).

  29.4.  Rendering

     o Move low-level code concerning scale and level-of-detail from
       d3::scene to d3::pt.
     o Remove older 3D rendering code.
     o Add decimation options --di-upper, --di-lower, and --do-try for
       reducing the complexity of 3D scene geometry, hence reducing the
       number of operations required for occupancy updating.

  29.5.  Filtering

     o Add support for filtering 3D output with --3d-filter. This is now the
       default behavior. Add an option --3d-chain for selecting the filter
       chain used for 3D output. (See --hl and --hq for details.)

  29.6.  User interfaces

     o Add fine-grain UI updates for 3D operations when using ui=tty. Reduce
       tty UI status update frequency to at most once per second.

  29.7.  3D Models

    29.7.1.  Rendering

     o Add support for synthetic focus via the --focus option, including
       focus with horizontal and vertical tilt. Adding simulated focus
       effects, including tilted and swung focal planes, was suggested by
       Gregory Maxwell.
     o Interpolate to generate smooth 3D depth output.

    29.7.2.  Geometry

     o Modify --3dpx to affect scene geometry rather than rendered pixels. In
       certain cases, this change should allow removal of objects close to
       the camera, hence revealing objects further away.
     o Fix dimension comparison bug in d3::space::traverse::get_next_split().
     o Implement an experimental approach to 3D subspace candidate selection;
       this seems to perform poorly in most cases due to parallax effects.
       See the source code for details. (Option --subspace-traverse)
     o Move code concerning the nature of space from d3::scene to d3::space.

    29.7.3.  Occupancy

     o Add adaptive weight decomposition to 3D occupancy algorithms.

  29.8.  Undocumented build options

     o Add to the Makefile a HASH_MAP option that can be used to assign the
       3D spatial info structure a hash map type instead of the standard STL
       map type. As this is likely to break things, it is currently
       undocumented. HASH_MAP=GNU seems to compile with g++ 4.0.x but has not
       otherwise been tested.

28. Version 0.8.3, 2005-Dec-23

  28.1.  Image files

     o Add an option --def-nn to allow definition of pixels in output images
       to take values from neighboring pixels within a certain radius, in
       cases where they would not otherwise be defined.

  28.2.  Rendering

     o Add option --3dpx to specify 3D regions to exclude during final
       rendering, using a single depth for each pixel in each frame of
       rendered output. (Evaluates at the depth used in depth-rendering.)

  28.3.  3D Models

    28.3.1.  Stereoscopy

     o Add option --pc to specify which pairwise comparisons should be
       performed.
     o Add option --pa to set the number of point candidates accepted for
       each pair of cameras (pairwise ambiguity). The default of 3 preserves
       existing default behavior.
     o Add option --tcem for scoring point candidates by third-camera views.
       The default of 0 preserves existing default behavior.

    28.3.2.  Geometry

     o Add --et option to specify encounter thresholds.
     o Clean up d3::scene to remove triangle-mesh code.
     o Modify representation of 3D subspaces so that refined subspaces are
       roughly cubical, and to allow refinements at multiple resolutions.

    28.3.3.  Occupancy

     o Fix bugs in 3D color and occupancy updating caused by bounding box
       miscalculation.
     o Add option --oui for determining occupancy update iterations. The new
       default is 10, halving the previous default of 20.

27. Version 0.8.2, 2005-Nov-22

  27.1.  Command line interface

     o Add magical file 'dump:' for listing color values numerically to
       stderr.

  27.2.  Control points

     o Fix various bugs in control-point alignment reported by Gregory
       Maxwell.

  27.3.  3D Models

     o Transition from a subdivisible triangle model to a subdivisible space
       model, using a rudimentary implementation of Hans Moravec's notion of
       occupancy.
     o Add support for view and depth output from arbitrary cameras.
     o Add clipping plane options for 3D modeling.

26. Version 0.8.1, 2005-May-6

  26.1.  Build

     o Fix enumerator compile bugs noted by Gregory Maxwell and Tom Holroyd
       to cause compilation failure under GCC 3.4.

  26.2.  Defaults

     o Modify --q1 to use median-value incremental rendering.

  26.3.  Exposure

     o Add a color adjustment option --exp-mult=.

  26.4.  Transformation data files

     o Add average magnitude comments to transformation data file output.

  26.5.  Control points

     o Add support for using control points in 2D and 3D alignment, as well
       as in 3D model construction. New options include '--gs points',
       '--cpf-load=', '--cpp-upper=', '--cpp-lower=', '--va-upper=', and
       '--st'.

  26.6.  User interfaces

     o Add support for median-value incremental and Irani-Peleg rendering.
       Using a statistic other than the mean was suggested by Scott Scriven
       as a means of eliminating non-uniform artifacts. Using the median
       seems to improve performance on Scott Scriven's example sequences, as
       well as on the scaled output of fine:sinc*lanc for sparse inputs.

  26.7.  3D Models

     o For 3D scene reconstruction, use a new unified surface model in place
       of the depth-based multi-model approach used in 0.8.0. The new model
       is adjusted on the basis of edge, angle, and color measures.

  26.8.  Source code organization

     o Move ale-psf-calibrate to a new scripts directory.

25. Version 0.8.0, 2005-Jan-12

  25.1.  Image files

     o Add support for PPM with extended attributes (EPPM). Attributes
       handled specially include black level, shutter speed, aperture, and
       ISO (or gain).

  25.2.  Exclusion regions

     o Set image offsets in d2/render/combine.h. This allows Irani-Peleg
       rendering to work with --crop when the default rendering chain
       includes more than one rendering invariant.
     o Replace functions d2::incremental::{increase,decrease}_extents() with
       new functions that take exclusion regions into account. The new
       functions should also fix a boundary-calculation bug reported by
       Gregory Maxwell.
     o Modify d2/render/ipc.h to handle exclusion regions more effectively.
     o Add --crop argument, which excludes the spatial complement of a
       specified area over a specified set of frames. Gregory Maxwell notes
       several advantages of internal over external crops, including
       preserving knowledge of position in the uncropped frame, which among
       other benefits allows natural handling of Bayer patterns.
     o Modify rx_parameters in d2/render.h to use the ale_pos data type
       instead of int. This should allow exclusion regions to be calculated
       more accurately.

  25.3.  Alignment

     o Modify euclidean alignment so that perturb-upper and perturb-lower
       apply to rotational arclength.
     o Modify d2::align to use unscaled input images when the scale factor is
       larger than 1.0, or when a scaled_filter interpolant is being used.
     o Modify d2::align::set_exposure_ratio() so that alignment weights and
       certainty values are taken into consideration.
     o Add a --cw option to weight alignment error by certainty values, as
       suggested by Gregory Maxwell. This allows the contributions of pixels
       at maxval to be diminished, which can increase alignment success in
       certain cases.

  25.4.  Rendering

     o Perform Irani-Peleg updating separately by channel instead of using
       vector operations. This allows divide-by-zero and other conditions to
       be localized to particular channels.
     o Modify the Irani-Peleg renderer to use estimate-based certainty. This
       seems to improve noise characteristics significantly.
     o Modify d2::render::ipc::_ip_frame_correct() so that exposure
       re-estimation uses a ratio of weighted sums instead of a weighted
       average of ratios.

  25.5.  Exposure

     o Add a flag --exp-meta-only which causes tonal registration to be
       performed only on the basis of exposure metadata (e.g., data encoded
       as EPPM extended attributes). This approach was suggested by Gregory
       Maxwell.
     o Write the results of tonal registration as a comment in the
       transformation data file.
     o Fix an index variable bug in d2::image_bayer_ale_real::trigger().
     o Modify d2::exposure one-sided certainty so that the 'one-sided'
       condition only applies to bright (>50%) areas. Applying it to dark
       areas has no clear benefit, and an experiment by Gregory Maxwell
       demonstrates that doing so can exacerbate noise.

  25.6.  User interfaces

     o Modify d2::image::scale() to allow scale factors in the interval (0,
       1), and modify the command-line interface and help text to reflect
       this change. --scale= now accepts all finite positive values.
     o Add user interface options --ui=stream and --ui=tty. The latter
       includes more detailed status output when terminal width information
       can be obtained (esp. when IOCTL=1 is set at compile time), and is the
       new default.

  25.7.  3D Models

     o Add experimental cost calculation routines to d3/scene.h.

  25.8.  Source code organization

     o Move certain user interface elements to the source subdirectory ui/.

24. Version 0.7.3, 2004-Dec-1

  24.1.  Build

     o Implement optimizations that reduce the memory footprint when 3D
       options are used.
     o Optionally (when OPTIMIZATIONS == 1) use the output of the default
       rendering chain directly as the Irani-Peleg initial approximation,
       instead of copying it.

  24.2.  Defaults

     o Add a check to ensure that at most one --q* option is specified. The
       issue of multiple --q* options being specified was raised on the ALE
       mailing list by Viktors Rotanovs. As there is currently no support for
       this, generating an error message is appropriate.

  24.3.  Rendering

     o Add incremental 3D reconstruction output.
     o Add support for the Canon 300D with a 50mm f/1.4 lens (specifying view
       angle), as well as experimental support for the 50mm f/1.4 lens at 1.4
       (specifying a linear PSF). Also add support for 50mm f/1.8 and 85mm
       f/1.8 lenses, specifying view angles as specified in the chart at
       http://www.acapixus.dk/photography/angle_of_view.htm
     o Move all PSF parsing logic to a new file: d2/render/psf/psf_parse.h

  24.4.  Exposure

     o For cases where --psf-match is specified, modify the exposure settings
       for the final input image (i.e., reference image) so that default
       exposure is used, and modify the bayer pattern settings so that no
       bayer pattern is used. (The first of these modifications requires
       changes in the way that the array of input exposures is stored.)

  24.5.  Filtering

     o Don't output final data when --psf-match is specified. Doing so would
       be useless anyway, and apparently causes a segfault.
     o Add support for PSF convolution and scalar multiplication.

  24.6.  User interfaces

     o Remove the reference to a non-existent web page in
       unsupported::fornow().
     o Modify help argument processing so that several help arguments can be
       specified at a time. Change the usage text to reflect this.
     o Fix concatenated help output; outputs from all help options are now
       represented. (3D help had been omitted in 0.7.2.)

  24.7.  3D Models

     o Allow device-specific bayer patterns to be overridden by the --bayer
       option.
     o Add an option for explicitly setting the camera view angle. Make the
       default view angle 43.7 degrees.
     o Modify the 3D cost reduction algorithm. The new algorithm seems to
       offer better results than the old in cases tested thus far, and does
       not require that spatial extension be enabled.

23. Version 0.7.2, 2004-Oct-26

  23.1.  Build

     o Add a rudimentary test suite. (from 0.7.1-patch2)

  23.2.  Command line interface

     o Print version information to stdout instead of stderr. (from
       0.7.1-patch2)

  23.3.  Image files

     o Add rudimentary device support for raw, linear files from the Canon
       EOS 300D (Digital Rebel) SLR. CRW files may not be directly usable
       under all configurations; in cases where they are not, Dave Coffin's
       dcraw program, with arguments -d -4, will produce a raw, linear PPM
       file. See http://www.cybercom.net/~dcoffin/dcraw/

  23.4.  Exclusion regions

     o In render::is_excluded(), add the offset before checking exclusion
       regions. (from 0.7.1-patch1)

  23.5.  Alignment

     o Add a new option --gs-mo to establish a minimum overlap area for
       global searches. This may allow more of Derrick Brashear's historical
       USGS contour map image sets to align successfully. (from 0.7.1-patch2)
     o Add support for --perturb-{upper,lower}=x%, where the value x% is
       specified as a percentage of the smallest image dimension. Use of
       percentages to specify bounds was suggested by Jeff Epler. (from
       0.7.1-patch1)
     o Add code to shrink the accumulated image in d2/render/incremental.h,
       so that superfluously large undefined areas are never present. This
       may improve operation of '--gs inner' in some cases. (from
       0.7.1-patch1)
     o In d2::align::_align(), rescale default_initial_alignment in parallel
       with the current transformation, so that it can be used again, if
       necessary. (from 0.7.1-patch1)
     o Add experimental options --perturb-source and --perturb-output, which
       allow some refinement of the manner in which perturbation occurs.
       (from 0.7.1-patch1)

  23.6.  Rendering

    23.6.1.  Scale

     o Allow the scale factor to be explicitly set to one. (from
       0.7.1-patch2)

  23.7.  3D Models

     o Add cost-minimizing code to reconstruct 3D scenes from 2D inputs.
       (This code is currently very experimental.)

22. Version 0.7.1, 2004-Aug-27

  22.1.  Build

     o Add speed optimizations for filtering in the Euclidean case, but leave
       these disabled, since they are not safe. (Also included in
       0.7.0-patch1.)

  22.2.  Alignment

     o Add global search option --gs to fix an alignment problem reported by
       Bert Douglas. (Also included in 0.7.0-patch1.)
     o Change transformation::eu_{get,set,modify}() so that externally
       visible values are interpreted in the context of transformations
       between scaled images, while internal values represent transformations
       between unscaled images. (Bugfix for 0.7.0. Also included in
       0.7.0-patch1.)
     o d2/tfile.h: Ensure that eu[] parameters are properly scaled when read
       and written. (Bugfix for 0.7.0. Also included in 0.7.0-patch1.)
     o Fix order-of-operations bug in d2::image::scale_by_half(). (Bugfix for
       0.7.0 and earlier versions. Also included in 0.7.0-patch1.)
     o Scale alignment weights for reduced level-of-detail in d2::align().
       (Also included in 0.7.0-patch1.)
     o For reduced level-of-detail alignment reference images, filter using
       alignment weights. (Also included in 0.7.0-patch1.)

  22.3.  Rendering

     o Add support for the ov7620 sensor (raw, linear modes only). (Updated
       from 0.7.0-patch1 to specify a linear PSF.)

  22.4.  Filtering

     o Add circular point-spread function option "circle=".

  22.5.  User interfaces

     o Add help mode --hA to display all help pages.

  22.6.  Video streams

     o Fix --visp segfault when not using last: filters.

21. Version 0.7.0, 2004-Aug-06

  21.1.  Build

     o Add support for algorithmic alignment weights. This requires POSIX
       fork() and execlp(), so add a Makefile variable for POSIX.

  21.2.  Command line interface

     o Increment the latest supported transformation file syntax to version
       3. This version supports transformation of the original frame, as well
       as other new features described above.

  21.3.  Defaults

     o Add multiple default settings: q0, q1, q2, qn, qr.

  21.4.  Image files

     o In the transformation data file handler, report incompatible
       transformation types as an error instead of as a warning.

  21.5.  Exclusion regions

     o Add option --ex, to support exclusion volumes. Region exclusion was
       first suggested to the author by Dewayne VanHoozer as a means of
       solving the 'closed eye problem' in group photography.

  21.6.  Alignment

     o Add support for frequency-based alignment weights. Angelo Pesce had
       initially suggested the related (or more general) idea of edge-based
       alignment. Frequencies were chosen because of their conceptual
       simplicity. This option requires that FFTW be linked.
     o Add support for specifying per-pixel and per-channel alignment weights
       by providing an additional weight-map image, as suggested by Bert
       Douglas.
     o Add options --fail-default and --fail-optimal to select the desired
       failure mode. --fail-default uses the default alignment in the case of
       failure.
     o Add a barrel distortion adjustment multiplier and rate options.
     o In d2/transformation.h, add parameters for barrel distortion
       correction. In d2/tfile.h, add new barrel distortion command 'B'. The
       approach taken is based on that of Helmut Dersch's PanoTools. (i.e., a
       polynomial in radial distance is used.)
     o Move d2/gpt.h to d2/transformation.h.
     o In d2::align, add support for original frame transformations.
     o In d2::align::diff() and d2::align::set_exposure_ratio(), treat cases
       with and without extension identically.

  21.7.  Rendering

     o Remove support for USM.
     o Modify the divisor in d2/render/ipc.h to ensure convergence when using
       multiple varieties.

  21.8.  Transformation data files

     o Report unrecognized transformation file commands as errors instead of
       warnings.

  21.9.  Control points

     o Add options to control output range. By default, use the range of the
       original frame.

  21.10.  Devices

     o Add a device type for the XVP610 camera in 640x480 mode.

  21.11.  User interfaces

     o Partition help into sections, and add a section for transformation
       data file help.
     o For incremental rendering, add general filtering options. Drizzling
       options are no longer supported as such, but the help output offers
       examples of how to emulate old drizzling/merging techniques (roughly).

  21.12.  Video streams

     o Add experimental video stabilization options.

  21.13.  3D Models

    21.13.1.  Rendering

     o Add experimental handling for Bayer patterns.

20. Version 0.6.0, 2004-Feb-10

  20.1.  Documentation

     o Update e-mail address information.
     o Modify the README to remove information covered in the User Manual.

  20.2.  Build

     o Add command-line options to select plain or raw PNM/PPM formats.
       Remove makefile variable PLAIN.
     o Add command-line options to select 8/16 bits per channel. Remove
       makefile variable BITS.
     o Change -Os to -O2 in the Makefile, since -Os no longer achieves
       speedup in the most critical codepaths.

  20.3.  Command line interface

     o Convert some operations on pixels and points into vector syntax
       through C++ operator overloading.

  20.4.  Rendering

     o In the Irani-Peleg renderer, skip frames that fail to reach the match
       threshold.
     o Revise the device configuration xvp610_320x240 to use a new filter,
       reflecting driver updates (see the relevant web page
       http://auricle.dyndns.org/xvp610/ ) and support for non-linear
       colorspace point-spread functions.
     o In the Irani-Peleg renderer, use a discrete Fourier transform to
       ensure that each (point-spread function, backprojection kernel) pair
       satisfies condition (9) from theorem 4.1 in the source paper.
     o Extend the --replace option to support drizzling.
     o Add a polymorphic point-spread function type psf and convert all
       external interfaces of ipc.h and usm.h (formerly hf-enhance.h) to use
       this type.
     o Fix memory leak in d2/render/combine.h:get_image(). (This fix is also
       included in a patch for 0.5.1.)
     o Modify the USM renderer to write output when incremental output is
       enabled.
     o In the USM renderer, now only defined pixel values contribute to the
       mask. Also, undefined values are no longer masked.
     o Modify the Irani-Peleg calibration script into a general point-spread
       function calibration script, using a new built-in point-spread
       function evaluation module to rate candidates.
     o Irani-Peleg and USM (High-frequency enhancement) renderers now use the
       same point-spread function configurations. New options --ips, --usm,
       --lpsf, --nlpsf, and --device subsume and extend the functionality
       provided by options --ip, --ipc, and --hf-enhance.
     o Add support for convolutions in non-linear colorspace. This feature is
       enabled and configured by the command-line option --nlpsf. (See also
       the item above.)
     o Linearize channel values within internal data structures so that most
       ALE operations are performed on linear data. Steve Mann discusses the
       use of linear representations in image processing, e.g. in his paper
       http://wearcam.org/comparametrics.pdf . We assume a simple power-law
       response by default.
     o Modify the image class to use a floating-point data type for storing
       pixels.
     o Revise identifiers and comments in d2/render/ipc.h to better reflect
       the terminology used in the source paper by Irani and Peleg.
     o Consoldiate code for computing the position and dimensions of a pixel
       in a new coordinate system, and use this new abstraction to reduce the
       code size of d2/render/ipc.h and d2/render/drizzle.h (Irani-Peleg and
       drizzling code, respectively).
     o Change several instances of 'double', 'float', and 'my_real' to
       specialized floating-point types 'ale_real', 'ale_pos', 'ale_sreal',
       and 'ale_accum'.
     o Fix offset calculation in d2/render/ipc.h. This is necessary for
       Irani-Peleg rendering of image mosaics extending upwards or to the
       left of the original frame. (This fix is also included in a patch for
       0.5.1.)

  20.5.  Exposure

     o Add a generalized, but rudimentary, implementation of Steve Mann's
       notion of 'certainty'. For more details, see
       http://wearcam.org/comparametrics.pdf
     o Add support for exposure registration (i.e., matching of exposure
       between different frames).

  20.6.  Filtering

     o Make stdin filter height and width independent of each other.
     o Add a point-spread function rasterizer.
     o Add command-line support for summation of point-spread functions.

  20.7.  Source code organization

     o Move classes treating snapshots as two-dimensional data to directory
       'd2' and create an associated C++ namespace. We can't use '2d' to
       label the namespace, because the C++ grammar won't allow it.

19. Version 0.5.1, 2003-Nov-19

  19.1.  Documentation

     o Several of the changes below are based on a suggestion by Bert Douglas
       regarding support for 16-bit-per-channel color. See the README for
       more information about relevant compilation options.
     o Add information to the README regarding new compilation options.

  19.2.  Build

     o Modify the makefile to accept a variable BITS, and differentiate
       between values BITS=8 and BITS=16. The latter option causes the macro
       BITS_16 to be defined during compilation.
     o Add a Makefile option for writing plain (ASCII) PPM files instead of
       raw (binary). This option causes the macro PPM_PLAIN to be defined
       during compilation.

  19.3.  Image files

     o Modify image_rw.h to handle 16-bit data when BITS_16 is defined. Also,
       differentiate between 8-bit and 16-bit ImageMagick builds by checking
       MaxRGB.
     o In ppm.h, add carriage returns to the set of recognized whitespace
       characters.
     o Modify ppm.h to read 16-bit binary PPM files (added to the PPM format
       spec in April 2000).
     o Modify ppm.h to read plain (ASCII) as well as raw (binary) PPM files.
     o Modify ppm.h to write plain (ASCII) PPM files when PPM_PLAIN is
       defined.
     o Modify ppm.h to output 16-bit PPM files when BITS_16 is defined.
     o Modify ppm.h to scale input intensity values based on the internal
       representation depth (8 or 16 bits per channel).

  19.4.  Exposure

     o Add a file 'channel.h' to describe the color channel data type and
       valid range, both being dependent on whether BITS_16 is defined. Use
       these generic values, where appropriate, throughout the ALE codebase.

18. Version 0.5.0, 2003-Nov-02

  18.1.  Documentation

     o Add more comment documentation to header files.
     o Change documentation for --replace.

  18.2.  Image files

     o Emit a more informative error message when the PPM file handler
       encounters a file that is not a well-formed PPM binary file.

  18.3.  Alignment

     o Remove certain cloning operations from align.h, but since cursory
       tests indicate that scaling with --scale is much more expensive than
       cloning, allow cloning to occur when scaling occurs.
     o Modify semantics of alignment following by applying to file-loaded
       initial transformations a delta transformation D = AB^-1, where B is
       the previous frame's (unmodified) initial transformation, A is the
       previous frame's final transformation, and ^-1 is the inverse
       operator. Using --follow with --trans-load can now improve alignment
       success when working with panoramic image mosaics.
     o We're not using simulated annealing, so remove comments that claim
       otherwise.

  18.4.  Rendering

     o Remove certain unsafe assumptions from ipc/* (now render/ipc/*); this
       change includes a modification to ipc.h (now render/ipc.h). Limits of
       the rectangle used as an argument to the ::response() function
       are now explicitly given rather than implied.

  18.5.  Source code organization

     o Move rendering implementations to subdirectory 'render/'.

17. Version 0.4.8, 2003-Aug-01

  17.1.  Alignment

     o Modify Monte Carlo alignment so that the same set of accumulated image
       pixels is examined when comparing two transformations.
     o Add an option for additional upper-bound constraint of rotational
       perturbation. Jeff Epler had noted that the
       perturb-upper/perturb-lower options alone may not be suited to working
       with sets of higher-resolution images.
     o Resolve a bug introduced in version 0.1.1 which had limited rotational
       perturbation to 2 degrees.
     o Add an option to adjust the maximum level of detail used. The default
       maximum is 2/perturb, which matches the default for previous versions
       of ALE.

  17.2.  Rendering

     o Modify Irani-Peleg renderer to produce incremental output.

  17.3.  Scripts

     o Modify names of temporary files used in the calibration script.

16. Version 0.4.7, 2003-Jul-27

  16.1.  Alignment

     o Irani-Peleg: don't truncate correction values in backprojection.
     o Irani-Peleg: don't multiply the weight function by a scale correction
       factor in backprojection.

  16.2.  Rendering

     o Irani-Peleg: add support for configurable modules, including a module
       that reads its configuration data from standard input and a module
       calibrated for an IBM (Xirlink) XVP610 in 320x240 mode. A rudimentary
       script for calibrating devices with unknown projection functions has
       been included as ipc/ale-calibrate.
     o Rename render::operator()() to render::sync(). Update subclasses
       accordingly.

  16.3.  Video streams

     o Add a replacement option suggested by Jeff Treece. This option can be
       used to facilitate video stabilization.

15. Version 0.4.6, 2003-Jul-01

  15.1.  Rendering

     o Allow --ip and --hf-enhance to be used together. [Modify
       ip::operator() and hf_filter::operator() so that multiple
       post-processing filters can be used.]
     o Initialize the drizzled image to be uniformly black. This fixes a bug
       introduced in 0.4.2.
     o Allocate the correct size image for drizzling. This fixes a bug
       introduced in 0.4.5.

14. Version 0.4.5, 2003-Jun-23

  14.1.  Command line interface

     o Reduce whitespace in usage() message.
     o Modify image file handler interface so that input files are not
       scaled. Perform scaling, when necessary, outside of the file handler.
       Since unscaled data is needed by the drizzling and Irani-Peleg code,
       this fixes bugs in those modules.

  14.2.  Image files

     o Remove call to stat() in image_rw.h. This improves OS independence,
       and apparently also allows URL-specification of images when compiled
       with ImageMagick support.

  14.3.  Alignment

     o Ensure correct transformation scaling and difference calculation after
       alignment is complete, even if alignment terminates with a reduced
       level of detail (i.e. perturb-lower > 2).
     o Separate the scale() function into two cases: scale() is reserved for
       scale factors greater than or equal to one, as in user-specified
       scaling; and scale_by_half() is used for the scale factor 0.5, needed
       to provide multiple levels of detail in alignment. Modify the
       scale_by_half() case to reflect source pixel values more fairly. (This
       change affects alignment behavior at reduced levels of detail.)
     o Modify align::diff() to use correctly scaled image offset values.
       (Bugfix for alignment with --extend.)
     o Modify align.h so that the image definition array is correctly scaled
       for all levels of detail. (Bugfix for alignment with --extend.)

  14.4.  Rendering

     o Modify image.h to correctly handle image offset values. (Bugfix for
       --extend operation.)

13. Version 0.4.4, 2003-Jun-06

  13.1.  Image files

     o Specify the binary mode flag to fopen() calls in the PPM file handler.
       This change resolves a bug discovered by Benjamin Hill.

  13.2.  Alignment

     o Modify the Monte Carlo pixel selection algorithm so that the expected
       number of sampled pixels more closely matches the specified number in
       typical cases.

12. Version 0.4.3, 2003-May-30

  12.1.  Alignment

     o Add support for Monte Carlo alignment of images, in which only a
       random subset of pixels is sampled.

  12.2.  Rendering

     o Add an option to disable incremental image output.

11. Version 0.4.2, 2003-May-23

  11.1.  Build

     o Add missing typecast to resolve compile warning under GCC 3.2.

  11.2.  Image files

     o Modify PPM file reader to correctly handle comments in PPM files; this
       resolves a bug pointed out by Benjamin Hill.

  11.3.  Alignment

     o Clean up source; move rendering and alignment functions into separate
       files.
     o Make changes to gpt.h that may reduce the Euclidean alignment time.

  11.4.  Rendering

     o Implement an image reconstruction option based on the work of Irani
       and Peleg.
     o Change valid drizzling diameter interval to (0,1].

  11.5.  Source code organization

     o Move ale.c to ale.cc to follow one of the many C++ naming conventions.

10. Version 0.4.1, 2003-Apr-28

  10.1.  Documentation

     o Separate into a number of subsections the option descriptions in the
       README
     o Add URL information to README

  10.2.  Build

     o Change language to C++.

  10.3.  Alignment

     o Add an option to use the previous frame's final transformation as the
       default alignment.
     o Modify the transformation algorithm to use transformations from the
       domain of the input image to the range of the target image. This
       change is reflected in transformation files. Maintain support for old
       transformation file versions, however.

  10.4.  Rendering

     o Add an experimental drizzling implementation. Research on drizzling by
       Richard Hook and Andrew Fruchter was brought to the attention of the
       author by Dan Kaminsky.
     o Change pixel weight data type so that more than 255 images can be
       merged.
     o Add support for increased spatial extents. Research on increased
       spatial extents by Steve Mann was brought to the attention of the
       author by Dan Egnor.

  10.5.  Transformation data files

     o Add version information to transformation files and update the version
       from 0 to 2.

  10.6.  Source code organization

     o Code cleanup in ale.c, image.h, and gpt.h.

9. Version 0.4.0p1, 2003-Apr-04

  9.1.  Build

     o Merge a bugfix from Debian ALE package version 0.4.0-1. Without this
       fix, an assertion failure can occur when ImageMagick support is
       enabled. Original fix implemented by Nick Rusnov.

8. Version 0.4.0, 2003-Mar-30

  8.1.  Rendering

    8.1.1.  Scale

     o Add support for general scaling parameters (i.e. all scale factors >=
       1.0). --scale2, --scale4, and --scale8 are now deprecated, and
       replaced with a more general --scale=x argument.
     o Support enhancement of high frequencies even when the scale factor is
       1.0.
     o Modify the high-frequency filter function so that the response is now
       (4/n)^2 times what it used to be, where n is the scale factor.

  8.2.  Filtering

     o Modify the high-frequency filter algorithm to support filtering near
       the border of an image.

7. Version 0.3.2, 2003-Mar-26

  7.1.  Filtering

     o Don't filter high frequencies if we're not enhancing them. This
       improves efficiency, but should not affect output.

6. Version 0.3.1, 2003-Mar-25

  6.1.  Rendering

     o Add support for post-enhancement of high-frequency details.

  6.2.  Transformation data files

     o Update informational output to transformation files to include
       original frame.

  6.3.  User interfaces

     o Output average match statistic.

5. Version 0.3.0, 2003-Jan-17

  5.1.  Build

     o Modify Makefile to compile with size optimization, since this appears
       to improve speed characteristics in some cases.

  5.2.  Alignment

     o Add an option to set the upper bound on correction steps.
     o Move transformation data structure and related functions to a separate
       header file.

  5.3.  Transformation data files

     o Add support for loading and saving transformation data.

4. Version 0.2.0, 2003-Jan-01

  4.1.  Alignment

     o Add support for general projective transformations, and change/add
       options as follows: '--translation' used to be '--no-rotate'
       '--euclidean' used to be '--rotate' '--projective' is a new option

3. Version 0.1.2, 2002-Dec-13

  3.1.  Image files

     o Add optional support for .jpg, .png, .tiff, and other file formats
       through ImageMagick. Translation using ImageMagick was suggested by
       Nick Rusnov.
     o Don't segfault if a file can't be opened.

2. Version 0.1.1, 2002-Dec-09

  2.1.  Alignment

     o Use reduced levels of detail in coarser alignment steps to increase
       speed.
     o Change perturbation step lower-bound check from less-than ('<') to
       less-than-or-equal-to ('<='). Change default lower bound to .125 from
       .1 (the behavior is the same, but the value makes more sense).
     o Change perturbation initial value to 32 pixels from 16 pixels, since
       coarse alignment is now less expensive.

  2.2.  Rendering

    2.2.1.  Scale

     o Modify scale function so that the borders aren't corrupted (too
       badly).

1. Version 0.1.0, 2002-Nov-26

  1.1.  Build

     o Add a rule for ale.exe to the Makefile.

  1.2.  Alignment

     o Add support for correction of rotation about the lens axis.
     o Add an option to adjust minimum step-size.
     o Add flags to specify which channels to use for alignment. Use a
       summation of all channels by default.
     o Add an option to modify the error metric exponent, and change the
       default value from 1 to 2.

  1.3.  Rendering

     o Add an optional match criterion for merging.

  1.4.  User interfaces

     o Display information about how well a new image matches the accumulated
       image.

0. Version 0.0.0, 2002-Oct-11

  0.1.  Initial release

     o Initial release.

# These exist entirely to fool aclocal when bootstrapping libtool.
#
# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
# which have later been changed to m4_define as they aren't part of the
# exported API, or moved to Autoconf or Automake where they belong.
#
# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
# using a macro with the same name in our local m4/libtool.m4 it'll
# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
# and doesn't know about Autoconf macros at all.)
#
# So we provide this file, which has a silly filename so it's always
# included after everything else.  This provides aclocal with the
# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
# because those macros already exist, or will be overwritten later.
# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6. 
#
# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
# Yes, that means every name once taken will need to remain here until
# we give up compatibility with versions before 1.7, at which point
# we need to keep only those names which we still refer to.

# This is to help aclocal find these macros, as it can't see m4_define.

# SYNOPSIS
#
#   ACX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
#
# DESCRIPTION
#
#   This macro figures out how to build C programs using POSIX threads. It
#   sets the PTHREAD_LIBS output variable to the threads library and linker
#   flags, and the PTHREAD_CFLAGS output variable to any special C compiler
#   flags that are needed. (The user can also force certain compiler
#   flags/libs to be tested by setting these environment variables.)
#
#   Also sets PTHREAD_CC to any special C compiler that is needed for
#   multi-threaded programs (defaults to the value of CC otherwise). (This
#   is necessary on AIX to use the special cc_r compiler alias.)
#
#   NOTE: You are assumed to not only compile your program with these flags,
#   but also link it with them as well. e.g. you should link with
#   $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
#
#   If you are only building threads programs, you may wish to use these
#   variables in your default LIBS, CFLAGS, and CC:
#
#          LIBS="$PTHREAD_LIBS $LIBS"
#          CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
#          CC="$PTHREAD_CC"
#
#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
#   has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
#   (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
#
#   ACTION-IF-FOUND is a list of shell commands to run if a threads library
#   is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
#   is not found. If ACTION-IF-FOUND is not specified, the default action
#   will define HAVE_PTHREAD.
#
#   Please let the authors know if this macro fails on any platform, or if
#   you have any other suggestions or comments. This macro was based on work
#   by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
#   from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
#   Alejandro Forero Cuervo to the autoconf macro repository. We are also
#   grateful for the helpful feedback of numerous users.

dnl From Paul Eggert and Derek Price.

dnl Sets INCLUDE_NEXT and PRAGMA_SYSTEM_HEADER.
dnl
dnl INCLUDE_NEXT expands to 'include_next' if the compiler supports it, or to
dnl 'include' otherwise.
dnl
dnl INCLUDE_NEXT_AS_FIRST_DIRECTIVE expands to 'include_next' if the compiler
dnl supports it in the special case that it is the first include directive in
dnl the given file, or to 'include' otherwise.
dnl
dnl PRAGMA_SYSTEM_HEADER can be used in files that contain #include_next,
dnl so as to avoid GCC warnings when the gcc option -pedantic is used.
dnl '#pragma GCC system_header' has the same effect as if the file was found
dnl through the include search path specified with '-isystem' options (as
dnl opposed to the search path specified with '-I' options). Namely, gcc
dnl does not warn about some things, and on some systems (Solaris and Interix)
dnl __STDC__ evaluates to 0 instead of to 1. The latter is an undesired side
dnl effect; we are therefore careful to use 'defined __STDC__' or '1' instead
dnl of plain '__STDC__'.

 * The algorithm in the source paper looks something like this (PSF' is the

 * This assumes a single colorspace representation.  However, consumer cameras
 * sometimes perform sharpening in non-linear colorspace, whereas lens and
 * sensor blurring occurs in linear colorspace.  Hence, there can be two
 * colorspaces involved; ALE accounts for this with linear and non-linear
 * colorspace PSFs.  Hence, the algorithm we use looks something like:

	 * zero values to mean 'undefined'.  Through this interpretation, the

	 * arrays to also serve as image definition arrays.
	 *
	 * Whereas scaling of image weight arrays is not generally obvious in
	 * either purpose or method, ALE requires that image definition arrays
	 * be scalable, and the method we implement here is a fairly obvious
	 * one.  In particular, if any source pixel contributing to the value of 
	 * a scaled target pixel has an undefined value, then the scaled target
	 * pixel is undefined (zero).  Otherwise, it is defined (non-zero).
	 * 
	 * Since there are many possible ways of implementing this function, we
	 * choose an easy way and simply multiply the numerical values of the
	 * source pixels to obtain the value of the scaled target pixel.
	 *
	 * XXX: we consider all pixels within a 9-pixel square to contribute.
	 * There are other approaches.  For example, edge pixels could be
	 * considered to have six contributing pixels and corner pixels four
	 * contributing pixels.  To use this convention, change the ': 0' text

*************************

Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005,
2006, 2007, 2008 Free Software Foundation, Inc.

   This file is free documentation; the Free Software Foundation gives
unlimited permission to copy, distribute and modify it.

Basic Installation
==================

   Briefly, the shell commands `./configure; make; make install' should
configure, build, and install this package.  The following
more-detailed instructions are generic; see the `README' file for
instructions specific to this package.

   The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation.  It uses
those values to create a `Makefile' in each directory of the package.
It may also create one or more `.h' files containing system-dependent
definitions.  Finally, it creates a shell script `config.status' that
you can run in the future to recreate the current configuration, and a
file `config.log' containing compiler output (useful mainly for
debugging `configure').

   It can also use an optional file (typically called `config.cache'
and enabled with `--cache-file=config.cache' or simply `-C') that saves
the results of its tests to speed up reconfiguring.  Caching is
disabled by default to prevent problems with accidental use of stale
cache files.

   If you need to do unusual things to compile the package, please try
to figure out how `configure' could check whether to do them, and mail
diffs or instructions to the address given in the `README' so they can
be considered for the next release.  If you are using the cache, and at
some point `config.cache' contains results you don't want to keep, you
may remove or edit it.

   The file `configure.ac' (or `configure.in') is used to create
`configure' by a program called `autoconf'.  You need `configure.ac' if
you want to change it or regenerate `configure' using a newer version
of `autoconf'.

The simplest way to compile this package is:

  1. `cd' to the directory containing the package's source code and type
     `./configure' to configure the package for your system.

     Running `configure' might take a while.  While running, it prints
     some messages telling which features it is checking for.

  2. Type `make' to compile the package.

  3. Optionally, type `make check' to run any self-tests that come with
     the package.

  4. Type `make install' to install the programs and any data files and
     documentation.

  5. You can remove the program binaries and object files from the
     source code directory by typing `make clean'.  To also remove the
     files that `configure' created (so you can compile the package for
     a different kind of computer), type `make distclean'.  There is
     also a `make maintainer-clean' target, but that is intended mainly
     for the package's developers.  If you use it, you may have to get
     all sorts of other programs in order to regenerate files that came
     with the distribution.

  6. Often, you can also type `make uninstall' to remove the installed
     files again.

Compilers and Options
=====================

   Some systems require unusual options for compilation or linking that
the `configure' script does not know about.  Run `./configure --help'
for details on some of the pertinent environment variables.

   You can give `configure' initial values for configuration parameters
by setting variables in the command line or in the environment.  Here
is an example:

     ./configure CC=c99 CFLAGS=-g LIBS=-lposix

   *Note Defining Variables::, for more details.

Compiling For Multiple Architectures
====================================

   You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory.  To do this, you can use GNU `make'.  `cd' to the
directory where you want the object files and executables to go and run
the `configure' script.  `configure' automatically checks for the
source code in the directory that `configure' is in and in `..'.

   With a non-GNU `make', it is safer to compile the package for one
architecture at a time in the source code directory.  After you have
installed the package for one architecture, use `make distclean' before
reconfiguring for another architecture.

   On MacOS X 10.5 and later systems, you can create libraries and
executables that work on multiple system types--known as "fat" or
"universal" binaries--by specifying multiple `-arch' options to the
compiler but only a single `-arch' option to the preprocessor.  Like
this:

     ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
                 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
                 CPP="gcc -E" CXXCPP="g++ -E"

   This is not guaranteed to produce working output in all cases, you
may have to build one architecture at a time and combine the results
using the `lipo' tool if you have problems.

Installation Names
==================

   By default, `make install' installs the package's commands under
`/usr/local/bin', include files under `/usr/local/include', etc.  You
can specify an installation prefix other than `/usr/local' by giving
`configure' the option `--prefix=PREFIX'.

   You can specify separate installation prefixes for
architecture-specific files and architecture-independent files.  If you
pass the option `--exec-prefix=PREFIX' to `configure', the package uses
PREFIX as the prefix for installing programs and libraries.
Documentation and other data files still use the regular prefix.

   In addition, if you use an unusual directory layout you can give
options like `--bindir=DIR' to specify different values for particular
kinds of files.  Run `configure --help' for a list of the directories
you can set and what kinds of files go in them.

   If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving `configure' the
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.

Optional Features
=================

   Some packages pay attention to `--enable-FEATURE' options to
`configure', where FEATURE indicates an optional part of the package.
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
is something like `gnu-as' or `x' (for the X Window System).  The
`README' should mention any `--enable-' and `--with-' options that the
package recognizes.

   For packages that use the X Window System, `configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the `configure' options `--x-includes=DIR' and
`--x-libraries=DIR' to specify their locations.

Particular systems
==================

   On HP-UX, the default C compiler is not ANSI C compatible.  If GNU
CC is not installed, it is recommended to use the following options in
order to use an ANSI C compiler:

     ./configure CC="cc -Ae"

and if that doesn't work, install pre-built binaries of GCC for HP-UX.

   On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
parse its `' header file.  The option `-nodtk' can be used as
a workaround.  If GNU CC is not installed, it is therefore recommended
to try

     ./configure CC="cc"

and if that doesn't work, try

     ./configure CC="cc -nodtk"

Specifying the System Type
==========================

   There may be some features `configure' cannot figure out
automatically, but needs to determine by the type of machine the package
will run on.  Usually, assuming the package is built to be run on the
_same_ architectures, `configure' can figure that out, but if it prints
a message saying it cannot guess the machine type, give it the
`--build=TYPE' option.  TYPE can either be a short name for the system
type, such as `sun4', or a canonical name which has the form:

     CPU-COMPANY-SYSTEM

where SYSTEM can have one of these forms:

     OS KERNEL-OS

   See the file `config.sub' for the possible values of each field.  If
`config.sub' isn't included in this package, then this package doesn't
need to know the machine type.

   If you are _building_ compiler tools for cross-compiling, you should
use the option `--target=TYPE' to select the type of system they will
produce code for.

   If you want to _use_ a cross compiler, that generates code for a
platform different from the build platform, you should specify the
"host" platform (i.e., that on which the generated programs will
eventually be run) with `--host=TYPE'.

Sharing Defaults
================

   If you want to set default values for `configure' scripts to share,
you can create a site shell script called `config.site' that gives
default values for variables like `CC', `cache_file', and `prefix'.
`configure' looks for `PREFIX/share/config.site' if it exists, then
`PREFIX/etc/config.site' if it exists.  Or, you can set the
`CONFIG_SITE' environment variable to the location of the site script.
A warning: not all `configure' scripts look for a site script.

Defining Variables
==================

   Variables not defined in a site shell script can be set in the
environment passed to `configure'.  However, some packages may run
configure again during the build, and the customized values of these
variables may be lost.  In order to avoid this problem, you should set
them in the `configure' command line, using `VAR=value'.  For example:

     ./configure CC=/usr/local2/bin/gcc

causes the specified `gcc' to be used as the C compiler (unless it is
overridden in the site shell script).

Unfortunately, this technique does not work for `CONFIG_SHELL' due to
an Autoconf bug.  Until the bug is fixed you can use this workaround:

     CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash

`configure' Invocation
======================

   `configure' recognizes the following options to control how it
operates.

`--help'
`-h'
     Print a summary of all of the options to `configure', and exit.

`--help=short'
`--help=recursive'
     Print a summary of the options unique to this package's
     `configure', and exit.  The `short' variant lists options used
     only in the top level, while the `recursive' variant lists options
     also present in any nested packages.

`--version'
`-V'
     Print the version of Autoconf used to generate the `configure'
     script, and exit.

`--cache-file=FILE'
     Enable the cache: use and save the results of the tests in FILE,
     traditionally `config.cache'.  FILE defaults to `/dev/null' to
     disable caching.

`--config-cache'
`-C'
     Alias for `--cache-file=config.cache'.

`--quiet'
`--silent'
`-q'
     Do not print messages saying which checks are being made.  To
     suppress all normal output, redirect it to `/dev/null' (any error
     messages will still be shown).

`--srcdir=DIR'
     Look for the package's source code in directory DIR.  Usually
     `configure' can determine that directory automatically.

`--prefix=DIR'
     Use DIR as the installation prefix.  *Note Installation Names::
     for more details, including other options available for fine-tuning
     the installation locations.

`--no-create'
`-n'
     Run the configure checks, but stop before creating any output
     files.

`configure' also accepts some other, not widely useful, options.  Run
`configure --help' for more details.

                3.5. Packaging

1.  0.9.0

  1.1.  Argument scope

     o Fix bugs in argument scope handling.

  1.2.  Multiple-pass registration

     o Revise alignment algorithm to allow multiple passes for less
       sensitivity to noise and better estimation of tonal certainty.

  1.3.  3D scenes and depth recovery

     o Revise 3D scene reconstruction algorithm to perform acceptably on a
       wider variety of scenes.

  1.4.  PSF windowing and infinite-support PSFs for Irani-Peleg rendering

     o Add syntax for PSF windowing and new PSF types with infinite support,
       including the gaussian kernel, suggested by HJ Hornbeck.

  1.5.  Variable lighting

     o Add a facility for handling variation in lighting between input
       frames.

  1.6.  Interchange formats

     o Add support for a commonly-used interchange format, such as autopano
       pto, suggested by Peter Miller.

  1.7.  Raw file handling

     o Use Dave Coffin's dcraw program to extract information from raw files,
       including pixel data, as well as black level and other meta-data, as
       suggested by Gregory Maxwell.

  1.8.  Abstract and partial transformations

     o Add a generic 2D transformation class, supporting partial
       transformations.
          o 'partial transformation', as used here, means that it is expected
            that some points will fail to map.
     o Add a partial 2D transformation class with constructor taking as
       arguments a pair of 3D projective transformations and a 3D model.

  1.9.  File scoping

     o Add new file-scoped options
          o Irani-Peleg
          o black level
          o alignment type
          o focus details

  1.10.  Irani-Peleg for 3D models

     o Modify existing Irani-Peleg code to use generic (partial) 2D
       transformations.
          o in combination with the above, this should allow the algorithm to
            operate on 3D models.

  1.11.  Focus bracketing for depth-of-field expansion

     o Add facilities for handling depth-of-field and focus bracketing in
       input image sets, as suggested by Viktors Rotanovs and Gregory
       Maxwell. This change will likely involve:
          o using the 3D model for depth data, as suggested by Gregory
            Maxwell
          o using user-provided (file-scoped) focus details to determine
            depth of field
          o using variable PSF in the Irani-Peleg algorithm, as suggested by
            Gregory Maxwell
          o developing an approach to handle the incremental
            (non-Irani-Peleg) case.

  1.12.  Output image characteristics

     o Allow specification of output image characteristics, including
       exposure (e.g., gamma) and channel offsets within a pixel.

  1.13.  Output devices

     o Add support for specifying output devices, such as LCD monitors, to
       allow shorthand customization of exposure (e.g., gamma) and other
       characteristics, such as channel offset in the case of LCD screens for
       sub-pixel anti-aliasing.

  1.14.  Weight and certainty upper bounds

     o Add support for specifying weight and certainty upper bounds for
       rendering, either as an absolute constraint or relative to average
       weights, so that the overall contributions to an output pixel (or
       channel) are constrained by weight.

  1.15.  Time locality

     o In combination with weight and certainty upper bounds, time locality
       could be used to determine which frames are used to generate an output
       pixel. As a special case of this, video stream processing could favor
       frames having the smallest time difference from the target frame.

2.  1.0.0 (Stable)

  2.1.  Performance

     o Refine rendering and alignment code for better performance.

  2.2.  Synchronized frame set syntax

     o Add syntax to identify synchronized frame sets.

  2.3.  Internationalization

     o Enhance the command-line interface in preparation for i18n. (?)
          o e.g., syntax for identifying synchronized frame sets
     o Internationalize the command-line interface and help text to
       accommodate translations.

  2.4.  Technical Manual Updates

     o Update the Technical Manual for information regarding 3D operation.

3.  Unsorted

  3.1.  Documentation

     o Generate correctly indented book-level tables of contents when
       rendering the complete set of manuals.
     o Add a tutorial, and credit Metin Toyran for suggesting a step-by-step
       guide.
     o Remedy meaningless page numbers for book title pages in the set ToC.
     o Complete migration of existing documentation from the localhost
       sub-directory, removing superfluous license terms in the footers.
     o Centralize licensing and authorship information (e.g., there should be
       only one COPYING file and only one AUTHORS file).
     o Include license and copyright terms for the doc tree Makefile as
       copyright notices in the AUTHORS and/or COPYING files (or equivalent).
     o Complete the documentation.
     o Revise the user manual for new features and syntax.
          o Document new scoping operators {}, [], and [<>].
          o Document other changes in UI, including regularization of syntax.
               + in particular, commas can no longer appear in
                 single-argument options when using assignment-delimited
                 syntax; use space-delimited syntax instead. This behavior is
                 inconsistent with 0.8.4.

  3.2.  Integer-value routines

     o Add facilities for manipulating images storing color as integer-valued
       data, possibly as library routines.

  3.3.  Library

     o Move image-processing routines into a library that can be used by
       other programs.

  3.4.  Language Bindings

     o Add bindings for other programming languages.

  3.5.  Packaging

    3.5.1.  Complete Package

     o Investigate options for distributing a 'complete' package including
       full revision history, pre-built documentation (if the ordinary
       distribution does not include this), and, possibly, example image
       sets. Direct download, bittorrent and CD are the most prominent
       candidates for distribution.
          o In the case of CD distribution, information should probably be
            added to the manuals regarding how to update CD-provided program
            source.

    3.5.2.  Windows Package

     o Investigate options for creating and distributing a combined source
       and binary Windows package containing sufficient software to ensure
       support for common image types (e.g., by statically linking with
       libraries for opening JPEG and PNG files). BitTorrent and CD are the
       most obvious candidates for distribution.
          o This package could build on the package described above, as a
            'for Windows' variant or some such.
          o This package could make use of an application such as
            InstallJammer or Nullsoft Scriptable Install System for
            installation.

title: Serious memory leak affecting all current versions.
desc: |-
  Jari Juslin reports in message '[ale] Processing color negative scans with ALE'
  an apparent out-of-memory condition affecting 0.9 branch with --ips 0.  Testing
  with 0.8.11.1 indicates that the 0.8 branch is affected also.  In particular,
  the following commands result in memory increase without bounds (e.g., visible
  in top or atop) throughout execution, which is unexpected for this
  configuration:
  
  $ convert -size 1000x1000 xc:gray gray.png
  $ ale-bin --cache 0 --no-inc --dchain zero --achain zero --perturb-upper=0 --ips 0 `for i in \`seq 1 1000\`; do echo -n "gray.png "; done` null:
  
  (Ignore the segfault following execution; this is a consequence of the 'zero'
  filter.)
  
  Running 'valgrind' on an input set of smaller dimensions and frame count reveals
  a number of memory leaks (reachable and unreachable) which have now been fixed.

    One approach to solving this would be restricting the candidate set size
    for each pixel in the map, so that, e.g., only regions neighboring a local
    region (allowing any level of decomposition) can be mapped.

##   (We might end up doing this anyway to support other compilers.)
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
##   -MM, not -M (despite what the docs say).
## - Using -M directly means running the compiler twice (even worse

## This next piece of magic avoids the `deleted header file' problem.
## The problem is that when a header file which appears in a .P file

## dummy dependencies for each header file.  Too bad gcc doesn't do

treated as uninstalled libtool libraries, other files are standard or library
object files.

If the OUTPUT-FILE ends in \`.la', then a libtool library is created,
only library objects (\`.lo' files) may be specified, and \`-rpath' is
required, except when creating a convenience library.

If OUTPUT-FILE ends in \`.a' or \`.lib', then a standard library is created
using \`ar' and \`ranlib', or on Windows using \`lib'.

If OUTPUT-FILE ends in \`.lo' or \`.${objext}', then a reloadable object file
is created, otherwise an executable program is created."

# is running under the msys shell), or in the following cross-
# build environments:
#    $build          $host
#    mingw (msys)    mingw  [e.g. native]
#    cygwin          mingw
#    *nix + wine     mingw
# where wine is equipped with the `winepath' executable.
# In the native mingw case, the (msys) shell automatically
# converts paths for any non-msys applications it launches,
# but that facility isn't available from inside the cwrapper.
# Similar accommodations are necessary for $host mingw and
# $build cygwin.  Calling this function does no harm for other
# $host/$build combinations not listed above.

# The TAGs below are defined such that we never get into a situation
# in which we disable both kinds of libraries.  Given conflicting
# choices, we go for a static library, that is the most portable,
# since we can't tell whether shared libraries were disabled because
# the user asked for that or because the platform doesn't support
# them.  This is particularly important on AIX, because we don't
# support having both static and shared libraries enabled at the same
# time on that platform, so we default to a shared-only configuration.
# If a disable-shared tag is given, we'll fallback to a static-only
# configuration.  But we'll never go from static-only to shared-only.
