sible patch offsets, achieving greater speed and memory efficiency. Natural structure of images. Second, the usual independent search for each pixel ignores the natural structure in images. In patch-sampling synthesis algorithms, the output typically contains large contiguous chunks of data from the input (as observed by Ashikhmin [2001]).
