Despite being at the focal point of intense research in both computer graphics as well as in computer vision, accurately reproducing the shape and appearance of real-world scenes remains a challenging problem, especially under uncontrolled conditions. One cue that has been used to separate diffuse and specular reflectance is polarization. Recent work in computer graphics has explored polarization of incident illumination in conjunction with spherical gradient illumination to infer high quality diffuse-specular separation of both albedo as well as photometric normal information [Ma et al. 2007]. Ghosh et al. [2010] improved upon this by removing the view-dependence of the polarization scheme of Ma et al. by analyzing the Stokes reflectance field under incident circularly polarized spherical gradient illumination, and recover more detailed specular reflectance information including index of refraction as well as specular roughness. |
