    abstract     = "Face recognition systems are typically required to work
under highly varying illumination conditions. This leads
to complex effects imposed on the acquired face image that
pertains little to the actual identity. Consequently, illumination
normalization is required to reach acceptable recognition
rates in face recognition systems. In this paper, we
propose an approach that integrates the face identity and
illumination models under the widely used Active Appearance
Model framework as an extension to the texture model
in order to obtain illumination-invariant face localization"
