Paper Abstract

In this paper, we describe a visual recognition system of the audience's reactions for multi-point tel-conferences. The system, which works in real-time, can recognize and evaluate some reactions of the audience. It is mainly composed of three subsystems. The first subsystem is a detection and tracking system which is used to detect face and hands from a complex background and track them. The second subsystem is a recognition system which can recognize gestures and poses of the human head, "ask" actions, and the concentration of the audience. The third subsystem is an information fusion system which is used to fuse the information from different sites and evaluate the reactions of the whole audience by using the recognition results in the second system. The outputs of this system are transmitted to the speaker in a remote location so that the speaker can do something according to the information received
