On this page Matlab code for some of my research and some general color image processing functions are available. It has not been optimized for speed, so feel free to adapt.

    Color Feature Description : matlab code for the hue and opponent color descriptor ( webpage ).

    Color Feature Detection : some color image processing functions, including color edge detection, photometric invariant, color Canny edge detection and Harris point detection ( webpage ).

    Color Constancy : matlab code for edge-based color constancy. The file also includes implementations of Grey-World, max-RGB and Shades of Grey ( webpage ).

    Color Naming : matlab code and color name assignment data for color naming ( webpage ).
