Color constancy between illuminants D65 and D50.

Wavelength nm of confusion hues and residual hues in illuminants D65 and D50 (from Figure 12), and (in last column) D50 wavelengths predicted from the D65 data by an accurate wavelength-based chromatic adaptation model (Pridmore [42]) for normal vision. Correlation coefficient between the last two columns is 0.99998, confirming the relationship between columns 1 and 2 is near perfect chromatic adaptation according to normal trichromatic vision.Color constancy between illuminants D65 and D50.本数据集包含标准光源D65与D50下混淆色（confusion hues）、残余色（residual hues）的波长（单位：纳米，数据源自图12）；末列则为针对正常视觉群体，通过Pridmore[42]提出的精准基于波长的色适应模型（chromatic adaptation model），由D65数据集预测得到的D50波长值。末两列的相关系数为0.99998，证实了基于正常三色视觉（trichromatic vision）的前提下，第1列与第2列的对应关系近乎完美地契合色适应规律。本数据集的研究主题为标准光源D65与D50之间的色恒常性（color constancy）。
