3D Video Coding for Realistic Multimedia Services

Abstract:

In recent years, various multimedia services have become available and the demand for realistic multimedia systems is growing rapidly. A number of three-dimensional (3D) video technologies, such as holography, two-view stereoscopic system with special glasses, 3D wide screen cinema, and multi-view video have been studied. Among them, 3D video coding is the key technology for various applications including free-viewpoint video (FVV), free-viewpoint television (FVT), 3DTV, immersive teleconference, and surveillance systems. The traditional video is a two-dimensional (2D) medium and only provides a passive way for viewers to observe the scene. However, 3D video can offer arbitrary viewpoints of dynamic scenes and thus allow more natural and realistic video. The 3D video can include multi-viewpoint video sequences captured by multiple cameras at the same time, but at different positions. Because of the increased number of cameras, the multi-view video contains a huge amount of data. Since this system has serious limitations on information distribution applications, such as broadcasting, network streaming services, and other commercial applications, we need to compress the 3D video sequence efficiently without sacrificing visual quality significantly. In this tutorial lecture, we are going to cover both the basics and the current state-of-the-art technologies for 3D video coding.

Biography:

Dr. Yo-Sung Ho received the B.S. and M.S. degrees in electronic engineering from Seoul National University, Seoul, Korea, in 1981 and 1983, respectively, and the Ph.D. degree in electrical and computer engineering from the University of California, Santa Barbara, in 1990. He joined ETRI (Electronics and Telecommunications Research Institute), Daejon, Korea, in 1983. From 1990 to 1993, he was with Philips Laboratories, Briarcliff Manor, New York, where he was involved in development of the Advanced Digital High-Definition Television (AD-HDTV) system. In 1993, he rejoined the technical staff of ETRI and was involved in development of the Korean DBS Digital Television and High-Definition Television systems. Since 1995, he has been with Gwangju Institute of Science and Technology (GIST), where he is currently Professor of Information and Communications Department. Since August 2003, he has been Director of Realistic Broadcasting Research Center (RBRC) at GIST in Korea. From September 2005, he has been a visiting scholar at University of Washington, Seattle, USA. He gave several tutorial lectures at various international conferences, including the IEEE Region Ten Conference (TenCon) in 1999 and 2000, the 2006 Pacific-Rim Conference on Multimedia (PCM), and the 2006 IEEE Pacific-Rim Symposium on Image and Video Technology (PSIVT). He is presently serving as an Associate Editor of both IEEE Transactions on Multimedia and IEEE Transactions on Circuits and Systems for Video Technology. His research interests include Digital Image and Video Coding, Three-dimensional Image Modeling and Representation, Advanced Source Coding Techniques, and Three-dimensional Television.
