Numerical 3-D Shape Inference from Image Brightness for Non-Lambertian Surface

Abstract

In this paper, we present an iterative algorithm that can be used to recover shape from shading for non-Lambertian surfaces using single incident light. In the method, the parameters determining the general reflectance map are identified using occluding boundary information. The normal of the object surface is estimated subsequently, and the 3-D shape is recovered. The experimental results show the effectiveness of our method for shape from shading.
