What overlaps? Does each block overlap other blocks, or do the blocks just overlap the original image with no block-to-block overlap (in essence the blocks perfectly tile the image like you were laying tiles on a floor)?

Change your
@(block_struct)kmeans(block_struct.data,4)
to
@(block_struct)kmeans(double(block_struct.data),4)
