In addition to the nice links Ryan gave, you might look at the rgb2ind() function in MATLAB, which I believe does something like what's described in this link:
http://en.wikipedia.org/wiki/Color_quantization
Also take a peek at the quadtree() function. It doesn't classify but just finds "uniform" areas.
