计算机图形学在需要高真实感的领域中的应用越来越多，这使得有必要检查图像评估和验证的方式。在这篇文章中，我们探索在任何试图量化渲染过程(从测量到显示)所实现的真实感水平的过程中，是否需要包括人类观察者。我们介绍了一个框架，用于测量真实场景和同一场景的计算机模拟之间的感知等价性(从亮度感知的角度)。因为这个框架是基于心理物理实验的，所以结果是从人类而不是机器视觉的角度来研究视觉而产生的。然后可以使用该框架来评估、验证和比较渲染技术。
Increased application of computer graphics in areas which demand high levels of realism has made it necessary to examine the manner in which images are evaluated and validated. In this paper, we explore the need for including the human observer in any process which attempts to quantify the level of realism achieved by the rendering process, from measurement to display. We introduce a framework for measuring the perceptual equivalence (from a lightness perception point of view) between a real scene and a computer simulation of the same scene. Because this framework is based on psychophysical experiments, results are produced through study of vision from a human rather than a machine vision point of view. This framework can then be used to evaluate, validate and compare rendering techniques.
