Abstract : This paper presents a real-time head/face tracking system that uses synchronized disparity and intensity frames from stereo cameras. It integrates stereo, morphological watersheds, gradient and feature extraction techniques to track the head/face. The face is tracked once the facial features, e.g. eyebrows, eyes, mouth and nostrils, are available. The head is tracked if the facial features are not available, e.g. when the person is away from the stereo head or when the head is in the profile view. Our approach automatically initializes without user intervention and can be re-initialized automatically if tracking of the 3D face pose is lost. The results on our face database and real image video sequences illustrate the effectiveness of the method.
