Patent Images

1. A computer-implemented method for encoding a sequence of images, comprising the steps of:

  • (a) padding each image to generate a padded frame; and

    dividing the padded frame for each image into a plurality of blocks using a tiling pattern wherein the blocks of said each image comprise a plurality of full-sized, interior blocks, wherein the plurality of full-sized, interior blocks are of equal size to one another and comprise all interior blocks of the image; and

    (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 the full-sized, interior blocks of adjacent images in the sequence of images to reduce tile edge-error build up during encoding; and

    (c) encoding the blocks of each image to generate encoded signals for each image.
