Abstract
A method of shadow removal from sole uncalibrated outdoor image is proposed. Existing approaches usually decompose the image into albedo and illumination images, in this paper, based on the mechanism of shadow generation, the occlusion factor is introduced, and the illumination image is further decomposed as the linear combination of solar irradiance and ambient irradiance images. The involved irradiance are achieved from the user-supplied hints. The shadow matte are evaluated by the anisotropic diffusion of posterior probability. Experiments show that our method could simultaneously extract the detailed shadow matte and recover the texture beneath the shadow.
