Lambertian Reflectance and Linear Subspaces. Ronen Basri. *. Dept. of Computer Science. The Weizmann Institute of Science. Rehovot, Israel. CiteSeerX – Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): We prove that the set of all reflectance functions (the mapping from surface. We prove that the set of all Lambertian reflectance functions (the mapping from surface normals to intensities) obtained with arbitrary distant.
Best lighting found for each model best fitting model wins. Abstract We prove that the set of all reflectance functions the mapping from surface normals to intensities produced by Lambertian objects under distant, isotropic lighting lies close to a 9D linear subspace.
