Abstract
A system and method involving the compression of palette-based color images. Compression is based upon coding for boundaries that exist in the original uncompressed image, where such boundaries effectively define a character of binary color differentiation between next-adjacent color zones, which differentiation can be expressed as N and not N, where N is one of the colors in the color palette of the original image.
