Abstract

This paper presents a non-perceptual color space based on spherical coordinates that is called  after ,  and . Like  space color,  decouples the information associated to chrominance  and intensity , however  keeps together the reddish colors. To show the potentials of our color space, we approach the problem of identifying either an image is a computer graphic or a photorealistic image. We got an average accuracy of  detecting computer graphics and outperforming the ones from ,  and  color spaces with statistically significative differences on classification average accuracy.  color space can be used in other issues where chrominance decoupling improves the discriminant capability.
