Abstract:The human visual system is able to rapidly and accurately infer the material properties of objects and surfaces in the world. Yet an inverse optics approach---estimating the bi-directional reflectance distribution function of a surface, given its geometry and environment, and relating this to the optical properties of materials---is both intractable and computationally unaffordable. Rather, previous studies have found that the visual system may exploit low-level spatio-chromatic statistics as heuristics for ma… Show more
