3D face recognition by point signatures and iso-contours
Iordanis Mpiperis, Sotiris Malasiotis, Michael Gerassimos Strintzis · 2007
The paper addresses the problem of face recognition from range images. A novel technique based on matching of level contours is proposed and compared with a variant of the point signatures algorithm. Their efficiency is investigated on conditions of changes in expression and pose, and presence of glasses. Using a large database of range images, comparative experimental results are presented, showing that iso-contours outperform point signatures both in computational efficiency and in recognition rates.
