Estimation of Pose and Illuminant Direction for Face Processing.
Roberto Brunelli · 1994
In this paper three problems related to the analysis of facial images are addressed: the estimation of the illuminant direction, the compensation of illumination e ects and, nally, the recovery of the pose of the face, restricted to in-depth rotations.The solutions proposed for these problems rely on the use of computer graphics techniques to provide images of faces under di erent illumination and pose, starting from a database of frontal views under frontal illumination.
