Facial Recognition Approaches and Methods with Feature Extraction:A Comprehensive Review

One of the huge avenues of research in image processing is facial recognition. Automatic Facial Recognition (FR) has many applications. The paper deals with the various methods of facial recognition system. It includes the various methods of face recognition system along with feature extraction which makes the facial recognition system more versatile and robust. An attempt is made to make a complete survey of all FR systems regarding the methodology adopted along with the researches that took place, the accuracy rate of the methods and also the advantages and the disadvantages of the various methods. The paper discusses all the methods of face recognition system with or without feature extraction and expression recognition. Face recognition system has seen many new methods of development to cover as many different possibilities as possible, along with high rate of accuracy. An extensive and elaborate survey and a walk through of all those methodologies are covered along with the algorithms followed by the methods for facial recognition.
