Abstract

In this talk, an efficient and effective system capable of locating a crowd of people in real time, using multiple cameras, will be presented. For each camera view, sample lines (originated from a vanishing point) of foreground objects are projected on the ground plane. Ground regions containing high density of projected lines are then used to find people locations. Enhanced from previous works, this people localization approach needs not project foreground pixels of all views to multiple reference planes or compute pairwise intersections of projected sample lines at different heights, resulting in significant improvement in computational efficiency. Furthermore, heights of people can also be estimated. Experimental results on real data show that comparable accuracy in people localization can be achieved with five times in computing speed compared with our previous approach.

Biography

Jen-Hui Chuang was born on March 27 1958 in Taipei, Taiwan, Republic of China. He received the B.S. degree in Electrical Engineering from National Taiwan University in 1980, the M.S. degree in Electrical and Computer Engineering from the University of California at Santa Barbara in 1983, and the Ph.D. degree in Electrical and Computer Engineering from the University of Illinois at Urbana-Champaign in 1991.

Between 1980 and 1982 he was a Maintenance Officer for HAWK missile system with the Chinese Army. Between 1983 and 1985 he was a Design and Development Engineer with the LSI Logic Corporation, Milpitas, California. Between 1985 and 1989 he was a Research Assistant with the Signal Processing Group at the Coordinated Science Laboratory, University of Illinois. Between 1989 and 1991 he was a Research Assistant with the Robot Vision Laboratory at the Beckman Institute for Advanced Science and Technology, University of Illinois. Since August 1991, he has been on the faculty of the Department of Computer and Information Science at National Chiao Tung University.

His research interests include robotics, computer vision, 3-D modeling, speech and image processing, and VLSI systems. Dr. Chuang is a member of IEEE and the Tau Beta Pi Society.
