Abstract

Abstract:

The uniformity of color appearance space is playing an important role in cross-media color management. And the uniformity of CIELab, CIECAM02 and IPT was tested by Munsell system and Ebner & Fairchild's constant hue data sets. X,Y and Z tristimulus values are used as input data to predict lightness, chroma and hue of color appearance models. The results showed that CIELab and IPT have the similar performance in lightness uniformity. The predicted lightness and Munsell V were linear with each other. The CIECAM02-Jab's lightness uniformity is a little worse because its predicted value is not identical when Munsell V is same. On chroma uniformity, CIELAB is the best one, while IPT is the worst one. On hue uniformity, IPT is better than CIECAM02-Jab and CIELab. And CIELab is the worst one.

Key words: cross-media, uniformity, Munsell system, constant hue data
