Abstract

ABSTRACT It is known that there is a black-white asymmetry in the psychophysical response; this is such that decrements are represented in the visual system by a larger magnitude than increments, that have an equal-magnitude deviation from the background. One interesting prediction arises from this black-white asymmetry that is: an homogeneously textured surface in which each dot belongs to a range of grays, and whose mean luminance is L, will be perceived as darker than a uniform surface with the same luminance L. We propose to explore this effect and analyze its potential consequences on the brightness perception of surfaces in illuminated scenes. For this purpose, we performed two experiments: in the first one, we showed that the texture biases the perception of surface brightness. In the second one, we showed, by testing the effect on simulated 3D realistic scenes, that textured walls are perceived as darker than identically painted walls with soft finish.

纹理对模拟场景中亮度感知的影响

摘要:心理生理反应存在黑白不对称;在视觉系统中，递减的幅度比递增的幅度大，两者与背景的偏差是相等的。从这种黑白不对称中产生了一个有趣的预测，即:一个均匀纹理表面，其中每个点属于灰色范围，其平均亮度为L，将被认为比具有相同亮度L的均匀表面更暗。我们建议探索这种影响，并分析其对照明场景中表面亮度感知的潜在后果。为此，我们进行了两个实验:在第一个实验中，我们展示了纹理对表面亮度的感知偏差。在第二篇文章中，我们通过在模拟的3D现实场景中测试效果，证明了有纹理的墙壁被认为比同样涂了软漆的墙壁更暗。
