CIECAM02模型对不同光泽度印刷色谱色貌预测评估

采用双目观察与匹配心理物理学实验，对高低两种光泽度半色调调幅网点印刷色谱进行视觉评价，将高光泽度和低光泽度印刷色谱的视觉平均数据分别与CIECAM02模型预测结果进行最小二乘法线性拟合. 结果表明:CIECAM02模型对高光泽度和低光泽度印刷色谱的模型预测结果与视觉平均数据总体成比较好的线性关系；CIECAM02模型对这两种光泽度印刷色谱色调和明度预测是可行的；对于三属性预测而言，同一光源下，高光泽度和低光泽度印刷色谱都是色调预测最好，明度次之，彩度最差；对于同一光源和相同颜色属性，CIECAM02模型对高光泽度印刷色谱的预测精度比低光泽度印刷色谱的预测精度高. 

Evaluation on the Prediction of CIECAM02 Model for Different Gloss Printing Atlas

Psychophysics experiment has been carried out in which color appearance of high-gloss and low-gloss printing atlas was assessed by using binocular viewing and matching method under three different light sources. A linearity fitting algorithm by methods of least squares was applied to evaluate the correlation between visual experiment data and predicted results through CIECAM02 model for high-gloss and low-gloss printing atlas. The research result has shown that there is a good correlation between visual experiment data and predicted results for high-gloss and low-gloss printing atlas. The correlation of hue and lightness between visual experiment data and predicted results is the best and the second best, respectively, under the same light source. Colorfulness is the worst. The predicted accuracy of CIECAM02 model for high-gloss printing atlas is better than that of low-gloss printing atlas under the same light source.
