| Research Abstract |
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.
