Face Recognition System and It´s Application

The most immediate and quickest method of human-computer interaction, which is the trend of the development of robots, is interacting with robots with the expression of human beings. (To realize this function, a face recognition system is necessary.) A face recognition system includes several parts, such as face detection, skin color detection, image processing, and so on. Two main methods of face recognition are introduced in this paper: bi-linear interpolation and improved linear discriminant analysis. What is performed at the end of the paper is an experimental research and analysis of the influence that lighting changes have on recognition rate.
