Title: Re-Live the Movie "The Matrix": From Harry Nyquist to Image-Based Rendering

Speaker: Prof. Tsuhan Chen, Department of Electrical and Computer Engineering, Carnegie Mellon University


Abstract: In recent years, the field of visual computing has observed a convergence of image processing, computer vision, and computer graphics. Multiview imaging represents one central theme of the convergence. Now widely used in applications ranging from special effects (e.g., in the movie "The Matrix") to 3D object tracking, multiview imaging has become an essential tool for creating informative visualization and effective 3D analysis. In this talk I will introduce recent research on sampling, reconstructing, and relighting multiview images. I will present our mobile camera array, composed of 48 mobile platforms each carrying a video camera. These mobile cameras respond to 3D scenes and position themselves for the most effective 3D analysis. While discussing the mechanism for sampling the 7-dimensional plenoptic function, we will reveal the connection between multiview imaging and the Sampling Theorem discovered by Harry Nyquist almost 80 years ago!



Tsuhan Chen has been with the Department of Electrical and Computer Engineering, Carnegie Mellon University, Pittsburgh, Pennsylvania, since October 1997, where he is currently a Professor and Associate Department Head. From August 1993 to October 1997, he worked at AT&T Bell Laboratories, Holmdel, New Jersey. He received the M.S. and Ph.D. degrees in electrical engineering from the California Institute of Technology, Pasadena, California, in 1990 and 1993, respectively. He received the B.S. degree in electrical engineering from the National Taiwan University in 1987. Tsuhan served as the Editor-in-Chief for IEEE Transactions on Multimedia in 2002-2004. He also served in the Editorial Board of IEEE Signal Processing Magazine and as Associate Editor for IEEE Trans. on Circuits and Systems for Video Technology, IEEE Trans. on Image Processing, IEEE Trans. on Signal Processing, and IEEE Trans. on Multimedia. He co-edited a book titled Multimedia Systems, Standards, and Networks. Tsuhan received the Charles Wilts Prize at the California Institute of Technology in 1993. He was a recipient of the National Science Foundation CAREER Award, from 2000 to 2003. He received the Benjamin Richard Teare Teaching Award at the Carnegie Mellon University in 2006. He is elected to the Board of Governors, IEEE Signal Processing Society, 2007-2009. He is a member of the Phi Tau Phi Scholastic Honor Society. He is Fellow of IEEE, and a Distinguished Lecturer of the Signal Processing Society.
