We introduce the intrinsic illumination subspace and its application for lighting insensitive face recognition in this paper. The intrinsic illumination subspace is constructed from illumination images of intrinsic images, which is a midlevel description of appearance images and can be useful for many visual inferences. This subspace forms a convex polyhedral cone and can be efficiently represented...
We present a method for pixel-based correspondence and shape reconstruction from multiple views of a moving object. Instead of relying on the brightness constancy assumption, this correspondence measure explicitly models intensity variations among multiple views, thus allowing estimation of lighting conditions and surface normals. The frontal-parallel assumption is not required either, since only...
