Detection and analysis of symmetrical parts on face for head pose estimation

In this paper, we demonstrate in the first that the amount (lengths and widths) of symmetrical parts on face are good and robust geometric features for head pose estimation. Secondly, we selected from all proposed algorithms of symmetry detection in the literature, the more suitable algorithm and the values of the proposed features are computed using some head poses which correspond to Yaw and Pitch motions. The obtained results demonstrate the validity of the proposed approach.
