摘要：
The IPT color space has been used in the study of gamut mapping and image color appearance model. The uniformity of IPT was investigated using Munsell system and Ebner and Fairchild's constant hue data sets, and compared with calculated ones of CIELAB color space. Tristimulus value X, Y and Z of Munsell data set with an illuminant of D65 were used as input of IPT and CIELAB to compute lightness, chroma, and hue. The calculated results showed that: IPT and CIELAB models have similar performance in lightness uniformity; CIELAB has better performance than IPT in chroma uniformity; on hue uniformity, the IPT is only better in blue area and has better linear relation in every hue angle than CIELAB with Munsell data set, however, the IPT is better than CIELAB with Ebner and Fairchild's constant hue data sets.
