色域匹配算法——CPC

色域匹配是实现原稿、显示器和印刷品的颜色匹配的关键技术。在色彩管理系统中,色域匹配算法来负责完成颜色的相互转换。本文介绍了一种优秀的匹配算法――CPC算法(色度均匀裁减法)。这种算法在进行裁减后能使色度和阶调保持一致性。人们对色度和阶调的复制效果的评价只能是主观性的,相对于其它三种传统的算法来说,CPC算法在色彩匹配主观评价方面是最好的。

Gamut mapping is a key technology which realizes good matching between original,displayed,and printed colors? Gamut mapping algorithms to device profiles achieve color transformation in color management systems (CMSs)?This paper introduce a new gamut mapping algorithm called 'Chroma Proportional Clipping (CPC)? This algorithm preserves chroma and tone?The reproduction of chroma and tone was evaluated subjectively?Compared with three conventional algorithms, CPC was given the best mean score in subjective evaluations of color matching?
