A Security System Based on Remote Iris Recognition

In this paper, we present a remote iris recognition system using two cooperative cameras, one of which with wide-angle perspective and the other with long focal-length and high resolution; the two cameras are fixed together on a resolving stage called Pan and Tilt. When the wide-angle camera finds a face, it locates the eye and instructs the Pan and Tilt to turn correspondingly, so as to allow the high resolution camera to see the eye as well. The technique allows the high resolution camera capture an iris image from a remote distance then to carry out regular iris recognition procedure. Due to the fusion of face tracking and iris recognition, the system achieves recognition accuracy up to 95%, at a working distance of over 100 cm.
