Recent releases


Changes: Many small bugs have been fixed. Most notably, the libraries should now build completely when compiled from scratch. Byte order bugs in reading and writing images have been fixed. New feature selection algorithms have been added.


Changes: Some performance tuning has been done. Corrections have been made in the object hierarchy, which still isn't totally ready. Peak detection methods have been added, and a neural network library has been initiated with the self-organizing maps. The graphics library is now able to draw in four different drawing modes.


Changes: This release contains a number of bug fixes and feature enhancements. Some matrix calculation errors have been corrected, a primitive image display (X windows) routine has been added, and binary image analysis methods have been rewritten and optimized. Furthermore, a circular Hough transform has been implemented, and the linear one was rewritten. The documentation was totally reformatted.


Changes: This release introduces a new primitive graphics library for annotating images. The code has been reorganized a bit, and a number of bugs have been fixed, most notably in the kNN classifier. Many missing features are now implemented.
