Abstract:
A computer-implemented method for encoding a sequence of images, comprising the steps of:(a) dividing each image of the sequence of images into a plurality of blocks using a tiling pattern, wherein the blocks of said each image comprise a plurality of full-sized, interior blocks, each having at least one edge, and wherein the plurality of full-sized, interior blocks are of equal size to one another and comprise all interior blocks of the image; (b) changing the tiling pattern for each image from image-to-image in the sequence of images so that the full-sized, interior blocks of said each image have a different size than, and edges which are offset from corresponding edges of, the full-sized, interior blocks of adjacent images in the sequence of images to reduce tile edge-error buildup during encoding; and (c) encoding the blocks of each image to generate encoded signals for each image.
