There has been a growing need for face recognition and face detection in security domain but still it is a challenging task for occluded faces with limited training samples. This survey shows various face recognition performs that paved way to the issue of partial occlusion problem in which the faces is camouflaged or masked to get rid of sanctuary system. Occlusion means frontage of the face image which may be because of wearing of sunspecs, hair or casing of facial image by cloth or other decorations. In real time application, face detection and recognition are vast researches area to deal many problems like partial occlusion, low-intensity images, and external occlusion by another face, not proper illumination. Occlusion is a challenging task compared to the other challenges. This paper reviews and compares five techniques used in occluded face detection and recognition.
