image=imread('lib.jpg');
patchsize=12;

I don't know what you want to do, so I can't give an answer. (Try to explain better - upload a diagram or image if you think that would help explain)
But I do know that you should not use "image" as the name of your variable because you'll destroy the built-in function by that name.

For more explanation let us suppose that I have a UV image in YUV color space.and I want to compute du=Uk-UJj and dv=Dk-Dj I think that in the paper k and j are two different colors if I am not wrong.Thanks

I = im2double(imread('cameraman.tif'));
Gsk = fspecial('gaussian',[12 12],3);
Idxy = I - imfilter(I, Gsk);
