Color matching algorithm based on computational 'color constancy' theory

This paper describes a new color appearance matching method based on color constancy theory. In order to achieve good color appearance matching between different color devices such as a CRT-monitor and a printer, whose whites are quite different, the method recovers the hypothetical surface reflectances of objects and the hypothetical spectral power distribution of the illumination in a scene. The hypothetical surface reflectances are changed in accordance with illumination changes and used to calculate corresponding colors under a target illumination. Our method requires no complicated calculation and gives good color appearance matching. Experiments have confirmed the validity of the proposed algorithm.
