基于色度裁减技术的评价方法

A Way for Evaluation of Chromic Clipping Techniques

该文介绍了一种基于色度裁减技术的评价方法，用三种不同的目标域来检测目标色域模型对不同匹配技术的影响。与以往方法的不同之处在于本文采用的是通过对单一颜色的比较推断出衡量出影响色相的主要因素。虽然连续色度裁减技术保持亮度不变，整体上是最优的，但也有例外的情况。实验结果指出了在全局趋势和特定例外情况下的一种折中方法，对于图像中的局部色域和目标色域有一定的借鉴意义。

This article describes a way of evaluation chroma clipping techniques for gamut mapping. Three destination gamuts are used to determine how the shape of the destination gamut would influence performance of the different mapping techniques. Different from the ways before, the article determines the influence in hue by the comparison of singnal color. Although the technology to reduce color in a row to maintain the same brightness, as a whole is the best, but there are exceptions. The results pointed out that the overall trend in exceptional and specific circumstances of a compromise approach, the image of local color gamut and objectives of the reference to a certain extent.
