Diffuse-Specular Separation using Binary Spherical Gradient Illumination
(The Eurographics Association, 2018)
We introduce a novel method for view-independent diffuse-specular separation of albedo and photometric normals without requiring polarization using binary spherical gradient illumination. The key idea is that with binary ...
Approximate svBRDF Estimation From Mobile Phone Video
(The Eurographics Association, 2018)
We describe a new technique for obtaining a spatially varying BRDF (svBRDF) of a flat object using printed fiducial markers and a cell phone capable of continuous flash video. Our homography-based video frame alignment ...
