Investigation of object color perception in three dimensional scene

物体颜色不能直接从反射光的物理色度中感知。视觉系统不自觉地从表面反射的光中减去光源的颜色。研究了三维深度线索对物体颜色感知的影响，并构建了一个基于场景亮度-色度信息的物体颜色感知模型。我们的心理物理学实验表明，双眼深度线索的显着效果和颜色空间中的亮度色度分布包络的重要性。采用我们的结果也提高了模型估计减去光源颜色的性能。

Object colors are not perceived directly from physical chromaticity of the reflected light. Visual system involuntary subtracts illuminant color from the light reflected from the surface. This study investigated the effect of 3D depth cue on object color perception and constructed a model estimating the subtracted illuminant color based on the luminance-chromaticity information in a scene. Our psychophysical experiments showed significant effects of binocular depth cue and the importance of luminance-chromaticity distribution envelope in a color space. Adopting our results also improved the performance of model estimating the subtracted illuminant color.
