With improvement in sensor technology 3d face recognition has become an imminent technology due to its non co-operative nature. Many researches in 3d face recognition have been dealing with the problem of pose variation, expression, aging and occlusion. We show that under utmost occlusion due to hair, hands, scarves, hates, glass typical 3d face recognition system exhibit poor performance. This paper presents restoration strategy for effective 3d face recognition. In this paper we propose two algorithms for occlusion detection and face recognition. First the occluded face region is detected by matching blocks with the original face. The non occluded regions are then used to restore the missing information. BMA used to restore occluded face. Then apply PCA for recognition. The experimental results show the higher computational efficiency and robustness to occlusion.
