Differential hysteresis processing
http://panda.uchc.edu/htklaus/Color/ Color.html
Even if you are infamiliar with hysteresis processing (DHP), you should check out this Web site from Klaus- Ruediger Peters (Peters@BSAC. UCHC.EDU) of the Molecular Imaging Laboratory of the University of Connecticut Health Center (Storrs, CT). In operation, DHP extracts differential color saturation contrasts from images. The result is that more information about color images can be revealed. You will also find links to the Molecular Imaging Laboratory, which is another worthwhile site.
