Abstract Digital video coding standards have become increasingly important due to the increasing popularity of multimedia applications. H.264AVC is the state-of-the-art video coding standard which improves video coding efficiency significantly, but with a cost of high computational complexity. It has been adopted for many applications including streaming video, high-definition DVD (HD-DVD), and wireless video. Video coding standards allow researchers to develop optimization algorithms and computation methods to optimize the video encoders and decoders for complexity reduction and for video quality improvement. The complexity reduction is important for wireless video applications where power consumption and cost are important concerns, and for high-quality applications where the resolution is high and real-time processing with low-cost processors is a concern. In this talk, we will review some of our work on video encoder and decoder optimization for lower complexity by exploiting statistical properties in the video. Specifically, we will discuss our work on statistical DCT computation and the extension of the concept to motion estimation and rate-distortion modeling, coding mode pruning, and deblocking filter speedup.
Biography
Ming-Ting Sun received his B.S. from National Taiwan University in 1976, M.S. from University of Texas at Arlington in 1981, and Ph.D. from UCLA in 1985, all in electrical engineering. He joined the University of Washington in August 1996 where he is a Professor. Previously, he was the Director of Video Signal Processing Research at Bellcore. He holds 10 patents and has published over 180 technical papers, including 12 book chapters in the area of video technology. He co-edited a book “Compressed Video over Networks,” and was the Editor-in-Chief of the IEEE Transactions on Multimedia (TMM) and a Distinguished Lecturer of the Circuits and Systems Society from 2000 to 2001. He received an IEEE CASS Golden Jubilee Medal in 2000, and was a general co-chair of the Visual Communications and Image Processing 2000 Conference. He was the Editor-in-Chief of the IEEE Transactions on Circuits and Systems for Video Technology (TCSVT) from 1995 to 1997. He received the TCSVT Best Paper Award in 1993. From 1988 to 1991, he was the chairman of the IEEE CAS Standards Committee and established the IEEE Inverse Discrete Cosine Transform Standard. He received an Award of Excellence from Bellcore for his work on the digital subscriber line in 1987. Dr. Sun is a Fellow of the IEEE.
