3-1 Surface Radiance Correction for Shape-from-Shading with Reflectance Property Estimation

Abstract

It is widely known that especially rough surfaces exhibit reflectance that is not well modelled by Lambert's law. In this case, standard Lambertian-based shape-from-shading methods cannot be applied straightforwardly to such rough surfaces. In this paper, we propose a novel method for simultaneously recovering the diffuse reflectance property and the Lambertian corrected images based on the Oren-Nayar model of diffuse reflectance.
