All releases of Motiontrack
Release Notes: This release now supports multi-processing when compiled with appropriate flags. It then forks into several processes, each computing an equal part of each image manipulation (for example filtering) task, and then synchronises the result to the parent process via half duplex Unix pipes. In this way it possibly improves performance on SMP CPUs, multi-CPU systems, or OpenMosix-like cluster solutions.
Release Notes: Movement Sectors are now visually outlined in the output image, and the speed of the sector check has been improved. Note that the names of most executables were changed to more unique ones to prevent conflicts with other projects, so scripts using motiontrack might have to be altered.
Release Notes: Motiontrack can now auto-normalize and auto-align to be compared images. This includes small rotations and/or perspective corrections of low angle. It's also possible to tweak the sector difference detection algorithm to work better for auto-comparison of generic images.
Release Notes: A complex re-design of the image manipulation filters has been done, supporting fuzzy tune values for almost everything now. Image resizing can now be done in any percentage of the original size. A brush size can be specified for the "enhance" and "blur" steps, tuning their behavior. "enhance" now works more like a real image frequency derivation, and additional values can be set to optimize speed performance. As always, some bugfixes have been made.
Release Notes: The ASCII art pattern detection now uses a real ASCII font with all available characters. Additional filter programs and steps were added to change image sizes, and several bugs were fixed and optimizations made.
Release Notes: In this version, image I/O code for the ImageMagick library has been speed optimized now, using a separate pixel buffer, making both GD and ImageMagick library usable in praxis. Additionally some optionally compileable debug output has been added, and a potential out of bounds bug has been removed.
Release Notes: Support for all image file formats provided by libGD has been added, and compilation runs successfully if at least one format can be both read and written. Alternatively, image I/O now supports the ImageMagick library, in which case libGD isn't needed at all anymore. However, this code is not yet as optimized and is slower.
Release Notes: In this release, things like redundant plausibility checks have been removed and the code has been tweaked in favor of speed, this way implementing the most important "features" of the speed patch in the project tree.
Release Notes: The code of the list-classes has been cleaned up. Most malloc(..)==NULL failures are now handled, to be less segfaulty afterwards, which is a must if anyone wants to re-use the code, especially the command line parser.
Release Notes: Pattern detection has been implemented as a first step on the way to object identification. 'asciiart' is the pattern-detection-demo-application which turns white on black line art into nice ASCII drawings.
