Open-set face recognition-based visitor interface system

Abstract

This work presents a real-world, real-time video-based open-set face recognition system. The system has been developed as a visitor interface, where a visitor looks at the monitor to read the displayed message before knocking on the door. While the visitor is reading the welcome message, using the images captured by the webcam located on the screen, the developed face recognition system identifies the person without requiring explicit cooperation. According to the identity of the person, customized information about the host is conveyed. To evaluate the system's performance in this application scenario, a face database has been collected in front of an office. The experimental results on the collected database show that the developed system can operate reliably under real-world conditions. © 2009 Springer-Verlag Berlin Heidelberg.
