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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
