Face verification from 3D and grey level clues

We address in this paper automatic face verification from 3D facial surface and grey level analysis, 3D acquisition is performed by a structured light system, adapted to face capture and allowing grey level acquisition in ali gnment. The 3D facial shapes are compared and the residual error after 3D m atching is used as a first similarity measure. A second similarity measure is derived from grey level comparison. As expected, fusing 3D and intensity information increases verification performances. The acquisition system, t he 3D and grey level comparison algorithms were designed to be integrated i n security applications in which individuals cooperate. (C) 2001 Elsevier S cience B.V.
