Intelligence Security Check System Using Face Recognition Algorithm: A Review

One of the famous biometric in use is the facial recognition, which uses statistical measurement of an individual face features to discover or determine his/her identity. Human are prone to errors or mistakes, therefore, using only security personnel cannot give us a perfect security mechanism. This paper explains the importance of biometric and also present various methods which biometric application can applied in solving various problem. It focuses on face recognition and face detection techniques which include Principle Components Analysis (PCA), Hidden Markov Model (HMM), and the Discrete Wavelet Transform (DWT). It briefly explains how the use of symmetry of the face can be used for recognition, the combination of audio and video in face recognition and also show that a face can be detected in a video. It also shows the various strengths and weaknesses from each method used.
