Estimating Illumination Direction of 3 D Surface Texture Based on Active Basis and Mojette Transform

Abstract

This paper describes an approach that, given an image of a rough surface texture, can estimate the direction from which the surface was lit. Unlike previous work, we require neither surface isotropy nor that the texture is included in the training set. The approach is based on Active Basis and the Mojette transform. The Mojette transform is used to estimate… (More)
