i grt error in this line
trunCoarseImg(:,:,:) = coarseImg((n+1):(end-n),(n+1):(end-n)); where n=6

Best Answer

You're specifying 3 dimensions for trunCoarseImg but only two for coarseImg. You can't do that. You'd have to assign that 2D coarseImg image to each color plane in trunCoarseImg one at a time.
