在CIECAM02-Jab 的基础上,使用XUT 数据集对明度、彩度、色相进行了优化,修正了均匀颜色空间,并对色差公式进行了欧几里德化,建立了一个基于Jab 颜色空间的色差公式。检验结果表明,新的色差公式计算色差的性能较好,而且其具有一个均匀的颜色空间,形式更为简单。

Lightness, chroma, and hue were optimized based on CIECAM02-Jab using XUT dataset. The uniform color difference was revised and a Euclidean color difference was derived. A color difference formula was based on Jab color space was established. The testing result showed that the new formula has better performance in calculating color difference and a uniform color space; it is simple in form.
