摘要
通过视觉匹配实验获得显示器(CRT)与打印体之间相同与不同色温下一组对应色数据,采用偏差分析了实验数据的可靠性,利用实验数据与已有的跨媒体对应色数据对Von Kries,CMCCAT2000和CAT02三种典型色适应变换和CIECAM02色貌模型的表现进行了评价和比较。结果表明,Von Kries与CMCCAT2000色适应模型表现相同,CMCCAT2000色适应变换模型的表现好于CIECAM02色貌模型,CIECAM02色貌模型的表现要好于CAT02色适应变换模型。结果与三种色适应变换和CIECAM02色貌模型在同种媒介中的表现不一致,这与模型改进过程中选择的数据以同种媒介对应色数据居多有关,而实验获得的对应色数据和对色适应评价结果将为跨媒体颜色再现中色适应模型及色貌模型的改进提供依据。
Abstract
A new set of corresponding-colors data between monitor and printer is obtained from a series of visual color matching experiments, and the data′s reliability is analyzed with deviation. The new corresponding colors data and the Braun and Fairchild data are used to test the performance of three chromatic adaptation transforms (i.e. Von Kries, CMCCAT2000 and CAT02) and the CIECAM02 color appearance model. The results show that Von Kries and CMCCAT2000 have the same performance, the CMCCAT2000 gives more accurate prediction than the CIECAM02, and the CIECAM02 gives more accurate prediction than the CAT02. The results are not consistent with the performance of three chromatic adaptation transforms and the CIECAM02 in predicting the corresponding colors for the same media. Previous study of chromatic adaptation transform and CIECAM02 use mainly the corresponding colors data for the same media. The new set of corresponding colors data and the results will provide a reference for the improvement of chromatic adaptation transforms and color appearance model of CIECAM02.
