The Radiometry of Multiple Images

We introduce a methodology for radiometric reconstruction, the simultaneous recovery of multiple illuminants and surface albedoes from multiple views, assuming that the geometry of the scene and of the cameras is known. We formulate the linear theory of multiple illuminants and show its similarities with the theory of geometric recovery of multiple views. Linear and non-linear implementations are proposed; simulation results are discussed; and, finally, results on real images are presented. keywords reconstruction, multiple views, linear models, radiometric recovery, Lambertian reflection, point light sources, ambiant illumination, surface albedo
