Abstract(in English)	Human can effortlessly perceive material property of surfaces such as glossiness and translucency. Given the fact that the image of a surface is resulting from complex interplay among the surface reflectance, 3D geometry, and illumination, visual estimation of the surface property may appear to involve highly complex neural computation in the brain. However, our recent psychophysical studies show that the human visual system utilizes simple features, or statistics, in the image to estimate the quality of natural surfaces. In this lecture, we introduce our psychophysical findings that reveal critical image features for the perceived glossiness and translucency, and a novel technique to alter the apparent material with simple image manipulation.
