In this paper, we describe a real-time face-tracking algorithm. We start with single face tracking based on statistical color modeling and the deformable template. We then expand ...

As an extension to prior work by the authors in the area of photometric normalisation for face verification, we apply these algorithms in a component-based framework. In particula...

In this paper, we address the problem of face tracking across illumination changes and occlusions. The method is based on leveraging the strengths of both Adaboost to deal with cl...
