Abstract
Recently
face recognition is attracting much attention in the society of network
multimedia information access. Areas such as network security, content indexing
and retrieval, and video compression benefits from face recognition technology
because "people" are the center of attention in a lot of video.
Network
access control via face recognition not only makes hackers virtually impossible
to steal one's "password", but also increases the user-friendliness
in human-computer interaction. Indexing and/or retrieving video data based on
the appearances of particular persons will be use-ful for users such as news
reporters, political scientists, and moviegoers. For the applications of
videophone and teleconferencing, the assistance of face recognition also
provides a more efficient coding scheme.
In this paper, we give an introductory course of
this new information processing technology. The paper shows the readers the
generic framework for the face recognition system, and the variants that are
frequently encountered by the face recognizer. Several famous face recognition
algorithms, such as eigenfaces and neural networks, will also be explained.
