Shape estimation in natural illumination
Webb1 feb. 2016 · This paper presents a novel approach for estimating the light direction, shape, and reflectance parameters from a single multispectral image by exploiting the notion … WebbAbstract. We introduce a method to jointly estimate the BRDF and geometry of an object from a single image under known, but uncontrolled, natural illumina-tion. We show that …
