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.

Albedo makes some pixels more ,inear. Published by Modified over 3 years ago. 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.

Assume lambertian reflectance for the faces e. Registration Forgot your password? We also provide a simple analytic characterization of this linear space. Lighting gt infinite DOFs. There is truly something for everyone! Most errors seem due to pose problems.

These results allow us to construct algorithms for object recognition based on linear methods as well as algorithms that use convex optimization to enforce non-negative lighting functions.
