Evaluation and modification of von Kries chromatic adaptation transform

Over the years, various chromatic adaptation transforms have been derived to fit the visual perception. However, some research demonstrated that CAT02, the most widely used chromatic adaptation transform, overestimates the degree of adaptation, especially for colored illumination. In this study, a memory color matching experiment was conducted in a real scene with the background adapting field varying in field of view, luminance and chromaticity. It showed that a larger field of view results in more complete adaptation. The results were used to test several existing chromatic adaptation models and to develop three new types of models. All of them improved the performance to some extent, especially for the illuminations with low CCT.
