Entropy constrained halftoning by tree coding

Abstract

An entropy constraint is introduced into a tree coding halftoner, so that one can control the degree of compressibility of the bi-level output images. The algorithm essentially trades image quality with compressibility as indicated by rate distortion theory. We demonstrate that this algorithm can generate halftone images that are of higher quality than… (More)
