Face Recognition. Personal Identification in Networked Society

Abstract

Identifying an individual from his or her face is one of the most nonintrusive modalities in biometrics. However, it is also one of the most challenging ones. This chapter discusses why it is challenging and the factors that a practitioner can take advantage of in developing a practical face recognition system. Some of the well known approaches are discussed along with some algorithmic considerations. A face recognition algorithm is presented as an example with some experimental data. Some possible future research directions are outlined at the end of the chapter.
