... to a cluster of pixels in an image, the proposed system applies individ- ual gradient selection for each pixel in the image. In order to avoid transmission of gradient information for each pixel, the ... However, the use of that update for the upper polyphase is essential to obtain anti- aliased low-low subimages. Without the anti-aliased low-low subimages, further decomposition...
