Abstract: Multimedia communication refers to a modern mode of communication in which signals in the form of text, voice, image, video, etc. may be mixed, processed, used and supported to bring out beneficial results. Multimedia signal processing involves techniques that allow efficient representation, reconstruction, transmission, and extraction of intelligence from these signals in order to realize the benefits. In this talk, key research areas related to multimedia signal processing are presented, including signal acquisition and presentation, coding, synthesis, and recognition and understanding. Selected topics in these areas are discussed in terms of recent advances as well as remaining challenges. With the proliferation of broadband networks, the need for multimedia processing technologies has grown tremendously, giving rise to a very interesting prospect in what is called "full-dimensional remote collaboration." We conclude the talk with a video that suggests this potential paradigm change in telecommunications.
Professor Juang received his Ph.D. from University of California, Santa Barbara. He had worked at Speech Communications Research Laboratory (SCRL) and Signal Technology, Inc. (STI) on a number of Government-sponsored research projects. Notable accomplishments during the period include development of vector quantization for voice applications, voice coders at extremely low bit rates, 800 bps and around 300 bps, and robust vocoders for use in satellite communications. He subsequently joined the Acoustics Research Department of Bell Laboratories in 1982, working in the area of speech coding, recognition and enhancement. Prof. Juang became Director of Acoustics and Speech Research at Bell Labs in 1996, and Director of Multimedia Technologies Research at Avaya Labs (a spin-off of Bell Labs) in 2001. In 2002, he joined Georgia Tech where he is Motorola Foundation Chair Professor and Eminent Scholar of Georgia Research Alliance. Prof. Juang has published extensively, including the book "Fundamentals of Speech Recognition", co-authored with L.R. Rabiner, and holds about twenty patents. His distinctions include: Fellow of IEEE (1991), Technical Achievement Award from the IEEE Signal Processing Society (1998), Bell Labs Fellow (1999), Member of (U.S.) National Academy of Engineering (2004), and Academician of Academia Sinica (2006).
