Over the past several years there have been many attempts to incorporate perceptual masking models into image compression systems. Unfortunately, there is little or no information on how these models perform in comparison to each other. The purpose of this paper is to examine how two different perceptual models perform when utilized in the came coding system. The models investigated are the Johnson-Safranek and the Watson. They both develop a contrast masking threshold for DCT based coders. The… CONTINUE READING
