Developments in sensor technologies have increased interest in face recognition. The face has become an emerging biometric modality, which is preferred especially in high security applications. Occlusion in an image is nothing but covering an object. Occlusion has been seen in many areas of image processing. It is seen in recognition of iris where the eyelashes occlude the iris; identification via ear can also be occluded by ear rings. Even in real time application face image is occluded via accessories such as sunglasses, beard, and hat. Dealing with these facial occlusions is a great difficult, which should be handled to enable applicability to fully automatic security systems.
