Modeling and tracking of faces in real-life illumination conditions
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 clutter and the image based parametric illumination model proposed by Kale and Jaynes. We show that a simple non-linear transformation of the Adaboost score multiplied with the illumination compensated likelihood leads to a fast robust tracking paradigm. We demonstrate the ability of our method to detect occlusions at the same time ensuring that misassignments between the occluder and the occluded does not occur. We present experimental results of our method on low resolution surveillance indoor and outdoor videos using an off the shelf DSP. We also demonstrate the power of the parametric illumination model for pose constrained face recognition when matching across known illumination conditions.
