3-1 反射特性推定を伴うShape-from-Shadingのための表面輝度補正(第3部門コンピュータビジョン)

抄録

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.
