摘要

针对CIELAB空间色调非恒常影响色域匹配及色差计算准确度问题

研究了色调恒常校正方法

建立了一种新的校正空间tLAB

并用其替代CIELAB空间实施色彩管理.首先

以孟塞尔空间为标准

分析了CIELAB空间的色调非恒常性.然后

利用孟塞尔新标数据对CIELAB空间实施色调校正

构建了色调恒常的颜色空间tLAB;借助三维查找表(3D

LUT)描述CIELAB和tLAB之间的非线性关系

提出了不增加时空代价的色彩管理工程实现方案.最后

给出了利用tLAB空间进行色域匹配的结果

以及新的色差评价指标体系.实验表明

利用tLAB空间进行色域匹配的效果明显优于传统方法

且用其替代CIELAB空间实施色彩管理具有很好的实时性和普适性.

Abstract

Hue nonconstancy of CIELAB color space affects the result of gamut mapping and the accuracy of color difference evaluation seriously.To solve this problem

a hue-constancy corrected method was proposed and a new color space tLAB was constructed

which was used to replace CIELAB during color management.Based on Munsell color space

the hue nonconstancy of CIELAB was analyzed firstly.Then the hue in CIELAB was corrected according to Munsell renotation Data

and the tLAB color space was created which was hue constant.Meanwhile

3D look up table(3D-LUT) was utilized to characterize the non-linear relationship between CIELAB and tLAB;an implementation scheme for color management with a low spatio-temporal cost was presented.Finally

the results of gamut mapping in tLAB color space and a new color difference evaluation were presented.Experiments show that the results of gamut mapping in the new tLAB space gain an advantage over the traditional ones.In addition

the color management using tLAB color space has real time performance and universality.
