ABSTRACT:

The increasingly widespread use of mobile and portable devices demands a
paradigm shift in the development of the next generation multimedia
communication systems. Recent research in mobile wireless image and video
transmission has responded to some of these demands. However, many
challenges remain. This talk will present some recent advances and
challenges in mobile wireless image and video communications. In
particular, two major areas of research will be discussed: (1) image and
video over MIMO (multi-input multi-output) systems, and (2) distributed
source coding for image and video transmission. In the case of image and
video over MIMO systems, major challenges, design strategies, and optimal
trade-off in transceiver and system design will be presented. In the case
of distributed source coding for image and video transmission, two main
applications are considered: (1) distributed systems where information
captured by individual sensing device needs to be conveyed to a central
node, and (2) standard centralized image and video coding system that is
capable of shifting the complexity at the encoder to decoder for mobile
device information gathering. One common challenge for both applications
is to explore an effective representation of the correlated sources for
the encoding and decoding of the image and video sources. Several recent
representations for distributed image and video source coding will be
discussed to illustrate the potentials as well as the sophisticated nature
of the practical distributed source coding.

Biography:

Chang Wen Chen received his BS from University of Science and Technology
of China in 1983, MSEE from University of Southern California in 1986, and
Ph.D. from University of Illinois at Urbana-Champaign in 1992. He is
currently Allen Henry Endow Chair Professor and Director of the Wireless
Center of Excellence at Florida Institute of Technology. He was on the
faculty of Electrical Engineering Department at the University of
Rochester from 1992 to 1996, on the faculty of Electrical and Computer
Engineering Department at the University of Missouri-Columbia from 1996 to
2003. He also served as the Head of Interactive Media Group at David
Sarnoff Research Labs from 2000 to 2002.

He is a Fellow of IEEE and will serve as the Editor-in-Chief for IEEE
Trans. Circuits and Systems for Video Technology starting January 2006. He
has been an Associate Editor for IEEE Trans. Circuits and Systems for
Video Technology from 1997 to 2005, an Associate Editor for IEEE Trans.
Multimedia since 2002, on the Editorial Board of Journal of Visual
Communication and Image Representation since 2000, and an Editor for IEEE
MutliMedia Magazine since 2003. He has also served as a Guest Editor for
several IEEE transactions and international journals. He is the Technical
Program Committee Chair for ICME2006 to be held in Toronto, Canada in July
2006, and has been Program Committee Chair for several multimedia related
conferences. His research interests include image and video coding, joint
source and channel coding, wireless and Internet video, wireless sensor
networks, and multimedia communication and networking. His research is
supported by NSF, DARPA, NASA, Whitaker Foundation, and Kodak.
