Application of Face Recognition Techniques in Video for Biometric Security

Abstract

Biometric based attributes are the latest additions to the existing mechanisms used for security of information system and for access control. Among a host of others, face recognition is the most effective biometric system for identification and verification of persons. Face recognition from video has gained attention due to its popularity and ease of use with security systems based on vision and surveillance systems. The automated video based face recognition system provides a huge assortment of challenges as it is necessary to perform facial verification under different viewing conditions. Face recognition in video continues to attract lot of attention from researchers world over hence considerable advances are being recorded in this area. The aim of this chapter is to perform a review of the basic methods used for such techniques and finding the emerging trends of the research in this area. The primary focus is to summarize some well-known methods of face recognition in video sequences for application in biometric security and enumerate the emerging trends.
