Paper Abstract

In this paper we describe the benefit of using a sharp transformation in the context of a color appearance model. The proposed scheme is shown to perform better than other models for the limited set of conditions tested. The testing method is similar to that described by Braun and Fairchild involving paired comparisons between prints under different illumination conditions and images calculated by the models for rendering on a CRT. Our testing shows that using a model that employs spectral sharpening for illuminant color compensation achieves better results than previous methods.
