摘要

The CIE 1997 interim color-appearance model, so called CIECAM97s, was tested by using the experiments done by CSAJ, Breneman, and McCann et al. The predicted results by CIECAM97s were compared with those by CIECAT94LAB, which consists of the CIE 1994 chromatic-adaptation transform with some improvements and the CIELAB formula. CIECAT94LAB is easy in computation, and can predict almost all the color-appearance phenomena. In addition, a new measure was proposed for comparing the predictability between various color-appearance models. The measure is independent of the scale used in each model. Using the method, it was shown that the above two models generally predicted the experimental results equally well. However some structural problems in CIECAM97s were raised.
