| 摘 要： | 在颜色复制过程中媒介之间色域大小和形状的差异将会对颜色的传递效果产生极大的影响，国内外提出了多种色域映射算法（GMA）来解决色域匹配问题。为了对新色域映射算法进行评价，国际照明委员会（CIE）发布了用于跨设备图像复制的色域映射算法评价准则，推荐由Jan Morovic提出的PGMA（公共色域映射算法）作为算法评价标准。本文分析了PGMA的原理，并在Visual C＋＋6．0环境中重新编译，采用新的源色域和目标色域对测试图像进行色域映射转换，对评价色域映射算法具有重要的作用。

| Abstract: | In the process of color reproduction, the media gamut differences in size and shape would greatly influence the result. To address the inconsistencies between the media gamut, domestic and foreign researchers have proposed lots of color gamut mapping algorithms （GMA）. In order to evaluate the newly proposed color gamut mapping algorithms, International Commission on Illumination （CIE） has put out guidelines for evaluating GMA,and recommends PGMA to be the standard which was proposed by Jan Morovic. In this paper, the principle of PGMA was analysed and compiled in Visual C＋＋ 6. 0, using new source gamut and destination gamut to process test image. It plays an important role in evaluating color gamut mapping algorithms. |
