Evaluating the effect of occlusion in face recognition systems

Face recognition systems as a biometrie system for human identification and verification has indeed shown a lot of progress over the years, illustrated through the various applications it has been used for. These applications include Human Computer Interaction systems, law, terrorist attacks, health and multimedia indexing. Furthermore, the installation of face recognition systems in public and private places helps with security improvement. However, occlusion as one of the major issues of the face recognition system tends to reduce its performance in real world applications. In this paper, the effect of occlusion scenario on face recognition technique was investigated. Also, the part of the occluded face region affecting the face recognition system is discussed.
