  • System for tile coding of moving images
    Patent number: 5471248
    Abstract: A video image frame consisting of a two-dimensional array of picture elements (pixels) is decomposed into a set of rectangular image portions (tiles). Within each tile, variance between pixel intensity values is less than a predetermined value. A tile is encoded by a value set identifying the tile and including a single intensity value for all pixels in the tile. Frame-to-frame variation of the video image is encoded by inter-frame tile comparison and encoding of sub-tiles representative of change from a previous frame to a current frame.
