You find a lot of color detection questions in this forum. Please take the time to read, how to detect red and yellow colors, and make a transfer to brown and white.

In "diff_im = imsubtract(data(:,:,1), rgb2gray(data));" you subtract the grey value from the red component. Are you sure this concerns the color yellow?!

Yes, I read that. Both brown and whit. I know. It should be easy to modify my apps, in fact the delta E app will work right out of the box. So how did it go? Do you have it working yet? By the way your code in your comment to Jan has nothing whatsoever to do with color segmentation, your comments notwithstanding. It just doesn't - I don't know why you think it should.
