已知影响图像质量的全色显示系统的两个一般特性包括显示系统传递调制（彩色和消色差）的能力和显示系统向信号添加噪声（彩色和消色差）的程度。本文描述了一个人类空间-彩色视觉模型和一个相应的程序，使用该模型来评估彩色显示系统。所提出的模型和过程一起构成响应于显示系统的调制传递和噪声生成特性的彩色图像质量度量。所提出的人类视觉模型采用的处理阶段，模拟模糊的光学眼睛，线性光谱吸收三类锥，增加内部噪声，非线性转导视网膜机制，推导的彩色图像，并计算响应的线性空间机制有限的空间频率和方向带宽。调制检测，歧视和阈上对比度感知性能的模型的总结，并与人类的视觉科学文献的性能数据进行比较。使用该模型的显示系统的评估程序的描述和显示系统的几个分析的结果。在模型中没有自由参数的情况下，已经获得了由模型做出的预测与来自显示器设计文献的图像质量研究的结果之间的高相关性。到目前为止进行的验证研究的结果表明，所提出的方法用于评估彩色显示系统是可行的，值得严格审查。
Two general characteristics of full-color display systems which are known to impact image quality include the ability of the display system to transfer modulation (chromatic as well as achromatic) and the degree to which the display system adds noise (chromatic and achromatic) to the signal. This paper describes a model of human spatial-chromatic vision and a corresponding procedure for using the model to evaluate color display systems. Together the proposed model and procedure constitute a color image quality metric which is responsive to the modulation transfer and noise generating characteristics of a display system. The proposed human vision model employs processing stages which simulate blurring by the optics of the eye, linear spectral absorption by three classes of cone, addition of internal noise, nonlinear transduction by retinal mechanisms, derivation of opponent-color images, and calculation of the responses of linear spatial mechanisms with finite spatial frequency and orientation bandwidth. A summary of the modulation detection, discrimination, and suprathreshold contrast perception performance of the model is presented and compared with human performance data from the visual science literature. A procedure for evaluating display systems using the model is described and the results of several analyses of display systems are presented. High correlations between predictions made by the model and the results of image quality studies from the display design literature have been obtained with no free parameters in the model. The results of the validation studies conducted so far suggest that the proposed method for evaluating color display systems is viable and warrants critical examination.
