Abstract
A set different dither matrices is employed in a repetitive manner to accomplish elimination of contouring while at the same time not adding typical 'dither graininess' to a digital video image. The matrices are specially chosen to result in a time-averaged zero dithering bias when applied frame-by-frame in a long sequence of frames.
