【摘要】 针对当前色彩管理研究缺乏可视化支持的现状,本文在研究相关理论和技术的基础上,将可视化技术应用于色彩管理,为其提供模型支持和可视化环境,形成了一套较完整的色彩管理可视化工具。该工具在获取彩色输入/输出设备彩色特性的基础上,通过构建几何模型对设备色域进行了精确描述;利用对色域的剖分操作,构造基于剖面的色域匹配模型;通过改善图象彩色特性获取的实时性,使其能有效获取图象源的特征并满足色彩管理的应用需求,支持了自适应色域匹配;对不同色彩空间样本的采集和对比显示有效体现了色彩的视觉差别,并提供了它们之间转换的误差分析;在探究不同色彩空间的颜色对应关系的基础上,实现了可视化的真彩颜色的自动生成,使可视化颜色更加逼真。上述功能及其相关技术可直接用于色彩管理的研究和实践,并对相关三维实体模型的可视化提供技术支持。
【Abstract】 A visualization tool is accomplished with aims on the demands of Color Management System, which gives the modeling method and provides with visualization environment. It describes the color characteristic of device accurately through constructing the geometric model and builds gamut mapping model in the section plane of gamut by dissecting. The improvement of image characteristic obtaining at real time satisfies the application and supports the adaptive gamut mapping. The sampling and visualization of sample set in different color space show the optic difference and give the error analysis of the color conversion between them. Based on the study of the color relation among the color spaces, the visualizing color can be created automatically with conversion formulas. The function and technology above can be directly applied to the research of Color Management System and practice, and can also give support to the model visualization of three-dimensional objects.
