i split the image pixels into many small matrices

A = imread('cameraman.tif');%load an included 256x256 example image
fun=@(x) max(x(:));
B=nlfilter(A,[3 3],fun);
%show input and output
figure(1),clf(1)%only use clf during debugging
subplot(1,2,1)
imshow(A)
title('original')
subplot(1,2,2)
imshow(B)
title('filtered')

The function can be as complicated as you want it to be.
