基于个体色度观察者的色适应生理优化模型

Physiologically Optimized Chromatic Adaptation Transform Based on Individual Colorimetric Observer

在传统色适应模型中引入个体色度观察者概念,量化由个体视觉生理差异引起的特性化色适应变换结果。在传统色适应模型的框架基础上,基于个体色度观察者模型获得表征个体视觉特性的视锥光谱响应函数,代入模型运算中完成个体观察者的色度描述和色适应变换。从而实现量化不同年龄和视觉特性的个体观察者在不同视场下的对应色预测,提出一种更精确且符合个体生理视觉特性的色适应模型优化算法。

The concept of“individual colorimetric observer”is introduced to the traditional chromatic adaptation transform to quantify the chromatic adaptation results of individual observers with different visual characteristics.The individual visual characteristics was quantified by their cone spectra response function based on the individual colorimetric observer model,and will be used to complete the individual colorimetric description and transform based on the framework of traditional chromatic adaptation transform.Thus,the corresponding color prediction of individual observers with different ages and visual characteristics under different visual fields can be quantified,and a more accurate,personalized and physiologically optimized model of chromatic adaptation transform is proposed.
