Method of detecting half-toned uniform areas in bit-map

摘要

A technique for detecting a non-uniform area in a half-toned bit-map including partitioning (111) a half-toned bit map into a plurality of image tiles, comparing (113) each image tile to a corresponding a half-toned reference pattern, and identifying (115) an image tile as comprising a half-toned uniform area if it matches the corresponding reference pattern. <IMAGE>
