基于CIECAM02颜色空间均匀性的研究

Research on the Uniformity of Color Space Based on the CIECAM02

颜色空间的均匀性是评价一个颜色空间质量好坏的一个重要方面,其均匀的程度对色差计算和色域映射的准确性有重要的影响。首先介绍CIECAM02,然后利用孟塞尔新标数据,分别从明度、彩度和色相三个方面评价CIECAM02-Jab的均匀性,评价的结果表明明度的均匀性较好,而彩度和色相的均匀性要相对差一些,需要做进一步的改进。

The uniformity is an important aspect for evaluating the quality of a color space and has an important impact on the accuracy of color difference and gamut mapping. The CIECAM02 is briefly introduced, and then the uniformity of the CIECAM02 - Jab is evaluated by lightness, chroma and hue using Munsell Renotation Data. The result of the evaluation shows that the uniformity of the lightness is better, the uniformity of the chroma and hue is relatively poor, so we need further improvement .
