在日常生活中，当我们遇到物体并计划与它们的互动时，识别材料并了解其特性非常有用，甚至可能至关重要。从视觉上得出的对材料特性的估计可以指导我们在何处以及用多大的力来抓住物体。然而，材料属性（例如光泽度）的估计是一个典型的不适定问题。我们用来估计光泽度的图像线索也受到形状、照明以及视觉显示中的色调映射的影响。在这里，我们重点关注后两者。我们定义了自然照明结构中存在的一些共性，并确定对这些自然“特征”的操纵是否会妨碍光泽恒定性。我们操纵照明场来违反自然照明的统计规律，使得光来自下方，或者亮度分布不再倾斜。这些操作会导致感知光泽度的错误。同样，色调映射对感知光泽度也有显着影响。然而，当在反映这些操作的信息丰富（而不是纯灰色）背景下查看对象时，光泽恒定性会得到一些改进：特别是，观察者在判断光泽时不易受到色调映射的影响。我们建议观察者在判断光泽度时对一些非常简单的环境统计数据敏感。
Recognizing materials and understanding their properties is very useful—perhaps critical—in daily life as we encounter objects and plan our interactions with them. Visually derived estimates of material properties guide where and with what force we grasp an object. However, the estimation of material properties, such as glossiness, is a classic ill-posed problem. Image cues that we rely on to estimate gloss are also affected by shape, illumination and, in visual displays, tone-mapping. Here, we focus on the latter two. We define some commonalities present in the structure of natural illumination, and determine whether manipulation of these natural “signatures” impedes gloss constancy. We manipulate the illumination field to violate statistical regularities of natural illumination, such that light comes from below, or the luminance distribution is no longer skewed. These manipulations result in errors in perceived gloss. Similarly, tone mapping has a dramatic effect on perceived gloss. However, when objects are viewed against an informative (rather than plain gray) background that reflects these manipulations, there are some improvements to gloss constancy: in particular, observers are far less susceptible to the effects of tone mapping when judging gloss. We suggest that observers are sensitive to some very simple statistics of the environment when judging gloss.
