An appearance-based face authentication system integrating
2D color or intensity images and 3D data is presented
in this paper. The proposed system is based on a low-cost
3D and color sensor, capable of synchronous real-time acquisition
of 3D images and associated color images. Novel
algorithms are proposed that exploit depth information and
prior knowledge of face geometry and symmetry to achieve
robust face detection, localization and authentication under
conditions of background clutter, occlusion, face pose alteration
and harsh illumination. A method for the enrichment
of face databases with synthetically generated views depicting
variations in pose and illumination is proposed to cope
with head rotations and illumination variations, avoiding
a cumbersome enrolment process. The performance of the
proposed authentication scheme is tested thoroughly on a
face database of 1500 images, recorded with the 3D acquisition
system. Experimental results demonstrate significant
gains resulting from the combined use of depth and color
or intensity information, in comparison to the use of 2D images alone.
