One of the more exciting and unsolved problems in computer vision nowadays is automatic, fast and full interpretation of face images under variable conditions of lighting and pose. Interpretation is the inference of knowledge from an image. This knowledge covers relevant information, such as 3D shape and albedo, both related to the identity, but also(More)
We present a fast and robust iterative method for interpreting face images under non-uniform lighting conditions by using a fitting algorithm which utilizes an illumination-based 3D active appearance model in order to fit a face model to an input face image. Our method is based on improving the Jacobian each iteration using the parameters of lighting that(More)
