And there are methods that are complete and really work, unlike what you mentioned which are merely steps along the way. See my File Exchange for 3 methods that actually do color detection/extraction. http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862

I'm sure in some of my File Exchange submissions I compute histograms. Why do you need to save the results of your 1 and 3? Don't you just need to detect the colors? Or is this a homework problem and you are required to do exactly what it asks for? If not, my code will find the colors for you quite easily and in a straightforward way.
