This paper addresses the problem of illumination variations affecting the performance of real world face recognition systems. We propose an exemplar (or appearance)-based technique to compute the canonical representation of the human face. The canonical image is equivalent to the reflectance field of the face that is invariant to illumination. We(More)
This paper proposes a new method to solve the problem of face recognition under varying illumination conditions. We introduce an exemplar-based technique to decouple and subsequently recover the canonical face and the illumination functions from the intensity images. The canonical image is equivalent to the reflec-tance field of the face that is invariant(More)
