3D Head Pose and Facial Expression Tracking using a Single Camera

: Algorithms for 3D head pose and facial expression tracking using a single camera (monocular image sequences) is presented in this paper. The proposed method is based on a combination of feature-based and model-based approaches for pose estimation. A generic 3D face model, which can be adapted to any person, is used for the tracking. In contrast to other methods in the literature, the proposed method does not require a training stage. It only requires an image of the person’s face to be tracked facing the camera to which the model is fitted manually through a graphical user interface. The algorithms were evaluated perceptually and quantitatively with two video databases. Simulation results show that the proposed tracking algorithms correctly estimate the head pose and facial expression, even when occlusions, changes in the distance to the camera and presence of other persons in the scene, occur. Both perceptual and quantitative results are similar to the ones obtained with other me...
