Face recognition is an interesting field of research for the purpose of person identification. Multiple techniques have been used to carry out this task. Face recognition undergoes some steps of pre-processing and then person identification is done. Pre-processing involves removal of noise, illumination effect and obtains face part. This face is used further for obtaining feature vectors and recognition of a person. In this paper, overview of some techniques is discussed with merits and demerits. This can help in building face recognition algorithm.
