Abstract
The invention relates to the application area of camera-based head and eye tracking systems. The performance of such systems typically suffers when eye glasses are worn, as the frames of the glasses interfere with the tracking of the facial features utilized by the system. This invention describes how the appearance of the glasses can be utilized by such a tracking system, not only eliminating the interference of the glasses with the tracking but also aiding the tracking of the facial features. The invention utilizes a shape model of the glasses which can be tracked by a specialized tracker to derive 3D pose information.
