Abstract :
This paper discusses a 3D tracking method allowing real-time recovery of the 3D position and orientation of a moving head. The described method uses a 3D wireframe model of the head, a 2D feature-based matching algorithm, and an extended Kalman filter estimator. The resulting motion tracking system works in a realistic environment without makeup on the face, with uncalibrated camera, and unknown fighting conditions and background
