Paper Abstract

Besides the advantage in statistical efficiency, coding images in certain transform domain also facilitates the adoption of the sensitivity function of the human visual systems (HVS). This involves establishing in that transform domain a subjective distortion criterion in the form of weighted mean square error. In this paper, after a brief review over some existing methods for that purpose, the method used in a recent study is described. Through a special arrangement with DCT coding, it is examined in parallel with the method by Katto et al. The rate-distortion relation from the coding process indicates that the two methods are robust and close in efficiency.
