Abstract :
This paper discusses the problems and solutions related to the reproduction of color images on displays. We focus on the problems of false contouring and gamut mismatches. A novel system consisting of a post-dithering algorithm and a hybrid gamut mapping algorithm is proposed to deal with the respective problems. The experimental results show that the proposed system mitigates the false contouring and increases the contrast in images.
