The Relation of Reference Pixels and Entropy in Error Diffused Images

Abstract

In order to develop the efficient Markov model coding methods for error diffused images, it is important to reveal the relation of the number of reference pixels and the conditional entropy, by knowing the combination of reference pixels which provides the minimum entropy when the number of reference pixels are given. In this paper, a practical searching method of the effective reference pixels for error diffused images is newly proposed, and the simulation result using the proposed method is reported.
