Finding Human Faces in a Face Database

Abstract

In this chapter, we introduce the technologies used in human face recognition. The different parts of a human face recognition system will be described, namely, locating human faces, extracting facial features, face recognition, and searching for faces from a database. Eigenface is a useful technique for face representation and recognition, which is reviewed in Section 19.2. The algorithms and techniques for detecting human faces in a complex background are described in Section 19.3. After detecting a human face, the techniques for extracting the respective facial features are presented in Section 19.4. Section 19.5 describes a method for human face recognition, which is efficient at searching a large face database.
