The perception of surfaces and materials

点击翻译按钮获取中文摘要

Our visual experience of the objects that populate our world arises from the interaction of light with surfaces. The way in which light is structured allows us to determine the material properties of objects. The appearance of surfaces allows us to determine whether the materials of which objects are composed are hard, soft, slippery, wet, pliable, brittle, or rough (to name just a few). The proposed work will seek to determine how the visual system computes complex surface properties from images, which can be broadly applied to the development of automated systems to determine the material properties of objects.
