Intelligence Security Check System Using Face Recognition Algorithm: A Review

Abstract

One of the famous biometric in use is facial recognition, which uses the statistical measurement of an individual face features to discover or determine his/her identity. Humans 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 in which biometric applications can be applied in solving various problems. It focuses on face recognition and face detection techniques which include Principle Components Analysis Hidden Markov Model (HMM) (PCA), Principal Component Analysis (PCA) and the Discrete Wavelet Transform (DWT). It briefly explains how the use of the 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 of each method used.
