打印机和图像色域提取算法

Algorithm of Color Gamut Extraction for Printer and Image

针对当前色彩管理研究缺乏提取图像色域算法及可视化技术支持的现状,提出了一种打印机色域提取算法。先确定打印机色域边界点,通过这些边界点利用几何方法快速构造色域外壳,对设备色域进行精确描述,并对色域及其剖面进行真彩色可视化。利用对色域的剖分操作,构造基于剖面的色域匹配模型。

This paper presents a new algorithm of color gamut extraction for printer with aims on the demands of color management system. Firstly the gamut boundary points of printer are determined, the gamut hull is constructed by geometric methods such as triangle faces to describe the gamut preciscly, both the gamut and its sections are visualized with the true color. Gamut mapping model in the section plane of gamut is built by dissecting.
