Abstract
An image is divided into blocks and coded by matching each block with a pattern having either a single region, or two or more regions defined by internal edges. The coded value of the block includes a pattern identifier, and a single pixel value for each region in the matching pattern. The coded image is decoded by constructing blocks divided into regions according to the pattern identifiers, and filling each region with the given single pixel value. The decoded blocks may be the same size as the blocks in the original image, or smaller, in which case the decoded image is reduced, or larger, in which case the decoded image is enlarged.
