Abstract

We introduce a methodology for radiometric reconstruction (i.e. 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 a linear theory of multiple illuminants and show its similarity to the theory of geometric recovery of multiple views. Linear and nonlinear implementations are proposed, simulation results are discussed and, finally, results on real images are presented
