| 目的 为了使数字输出设备的色彩复制更加保真， 提出一种新的色域映射算法。 方法 在基于改进凸壳算法色域边界描述算法的基础上， 以 ECI 2002， IT8.7/4和 TC3.5 色表为特征点提取对象， 提出基于特征点的临近替代映射算法， 并在 Epson Stylus Pro 7910 设备上通过实验对该映射算法的应用效果进行主客观评价。 结果 基于特征点的临近替代算法与基于改进凸壳算法的色域边界描述算法匹配效果良好。 结论 根据最后的 Z分值可知， 文中提出的映射算法以 ECI2002色表为特征点时应用效果最佳。 |

| Objective In order to improve the color copy fidelity of the digital output device, this paper presented a new color gamut mapping algorithm. Methods With the improved algorithm of convex hull algorithm based on color gamut boundary description, the ECI 2002 color table, IT8.7/4 and TC3.5 were the objects of feature extraction, a new gamut mapping algorithm was proposed in this study, namely, the neighboring replaced mapping algorithm based on the feature points. Through experiment on Epson Stylus Pro 7910, subjective and objective evaluations were conducted for the application effect of this mapping algorithm. Results The experimental results showed that the matching effect of the two algorithms was good. Conclusion According to the final Z score sheet, the neighboring replaced mapping algorithm based on the ECI2002 had the best application effect. |
