The resurgence of interest in 3D films, both from Hollywood and moviegoers, has launched a new era in visual media consumption and research. The public awaits new gadgets that will free them from the two-dimensional confines of existing imaging technology, and the corporations are all eyeing the limitless market for the next hot product. Every major electronics manufacturer has released, or will soon be releasing, a 3D video or gaming system. Meanwhile, researchers are busy sorting out issues such as compression of 3D imagery, transmission over a limited bandwidth channel, and display on various devices with competing standards.
However, perhaps the most important issue with 3D video technology has been overlooked or at least neglected: 3D image/video quality. Video quality is more critical in 3D than in 2D since viewers will also be sensitive to the impression of depth. In 3D, the difficulty is compounded by the fact that there is no physical image to evaluate; the impression of depth is simply an illusion. In this talk, we give an overview of the three important research issues in 3D: disparity estimation, view synthesis and quality metric, and discuss how they are integral building blocks of any 3D systems.
Truong Q. Nguyen received the B.S., M.S., and Ph.D degrees in electrical engineering from the Caltech in 1985, 1986 and 1989, respectively. He is currently a Professor at the ECE Dept., UCSD. His research interests are video processing algorithms and their efficient implementation. His current projects include 3D video processing and communications, LCD modeling and analysis, saliency in video, and novel medical devices. He is the coauthor (with Prof. Gilbert Strang) of a popular textbook, Wavelets & Filter Banks, Wellesley-Cambridge Press, 1997. He has over 300 publications.
Prof. Nguyen received the IEEE Transaction in Signal Processing Paper Award for the paper he co-wrote with Prof. P. P. Vaidyanathan on linear-phase perfect-reconstruction filter banks (1992). He received the NSF Career Award in 1995 and is currently the Series Editor (Digital Signal Processing) for Academic Press. He served as Associate Editor for the IEEE Transaction on Signal Processing from 1994-96; for the IEEE Transaction on Circuits & Systems from 1996-98 and for the IEEE Transaction on Image Processing from 2002-2004. He is a Fellow of the IEEE.
