Wavelet-based Light Reconstruction from a Single Image
2007
Fourth Canadian Conference on Computer and Robot Vision (CRV '07)
In this paper we propose a wavelet-based light representation. This representation is used for recovering illumination and reflectance of a scene with known geometry from a single calibrated image. Previous approaches of light estimation reconstruct either a discrete set of infinite light sources or the projection of light on the spherical harmonics basis. The first approach is more suitable for modeling sharp light effects while the second one works best for diffuse scenes. In contrast, we
