					      Identification Technology with Face Image Recognition




                                                                                                      FUKUI Kazuhiro           YAMAGUCHI Osamu




          We have developed a real-time face recognition technology using image sequencing. The face recognition is user-friendly
     because it can recognize a person without the need for physical contact. It is therefore suitable for use in security systems. To
     realize practical face recognition, it is necessary to deal with variations in facial expression, face direction, lighting conditions, and
     other factors. Our method can overcome such variations with image sequencing. This method has been installed in a PC access
     control system and a facility access control systems.
