当一个场景的照明发生变化时,该场景引发的视觉信号也会发生变化。尽管有这些变化,在一个场景中的物体往往保持不变的表观颜色。我们首先讨论用于量化颜色稳定性的心理物理程序。光照变化对视觉信号施加的变换决定了视觉系统必须“撤销”什么以达到恒定。这个问题在数学上是不确定的,只能通过利用视觉世界的规律来解决。在过去的十年里,随着技术的进步使得对大量环境场景和光源进行经验测量成为可能,我们对这些规律的认识有了实质性的增长。这篇综述提供了人类色彩恒常性模型的分类,首先是基于它们对如何简化反变换的假设,其次是基于如何通过复杂场景的元素设置反变换的参数。用图形和图形表示了人类色彩恒常性的候选算法,并讨论了准确估计光源的可用性和实用性。在整个回顾中,我们考虑了原则上可用的信息和视觉系统实际使用的信息的经验评估。在最后一节中,我们将讨论在我们的视觉系统中这些计算可能被实现的地方。
When the illumination on a scene changes, so do the visual signals elicited by that scene. In spite of these changes, the objects within a scene tend to remain constant in their apparent colour. We start this review by discussing the psychophysical procedures that have been used to quantify colour constancy. The transformation imposed on the visual signals by a change in illumination dictates what the visual system must ‘undo’ to achieve constancy. The problem is mathematically underdetermined, and can be solved only by exploiting regularities of the visual world. The last decade has seen a substantial increase in our knowledge of such regularities as technical advances have made it possible to make empirical measurements of large numbers of environmental scenes and illuminants. This review provides a taxonomy of models of human colour constancy based first on the assumptions they make about how the inverse transformation might be simplified, and second, on how the parameters of the inverse transformation might be set by elements of a complex scene. Candidate algorithms for human colour constancy are represented graphically and pictorially, and the availability and utility of an accurate estimate of the illuminant is discussed. Throughout this review, we consider both the information that is, in principle, available and empirical assessments of what information the visual system actually uses. In the final section we discuss where in our visual systems these computations might be implemented.
