Abstract

The ITU-T Video Coding Experts^Ò Group (VCEG) is currently developing a next-generation video coding standard known as H.26L. This draft standard, which is scheduled for completion in 2002, offers new levels of compression performance and additional features beyond those available in earlier standards. However, these advantages come at the cost of increased complexity and computational demands.

In this presentation, we analyze the rate-distortion performance of the H.26L standard and present algorithms that increase the speed of video encoding while making minimal sacrifices in terms of rate-distortion performance. In particular, we present a detailed analysis of the features of H.26L that lead to improvements in compression performance. Through this analysis, we will establish a foundation for the development of reduced-complexity encoding algorithms that are intended to enable real-time video applications that can benefit from the improved compression performance of H.26L on current and emerging hardware platforms.

Biography

FAOUZI KOSSENTINI received the B.S., M.S., and Ph.D. degrees from the Georgia Institute of Technology, Atlanta, in 1989, 1990, and 1994, respectively. He is presently an associate professor in the Department of Electrical and Computer Engineering at the University of British Columbia, where he is involved in research in the areas of signal processing, communications and multimedia, and more specifically in subband/wavelet image transformation, quantization, audiovisual signal compression and coding, channel error resilience, joint source and channel coding, image and video communication and image analysis. He has co-authored more than one hundred and twenty journal papers, conference papers, and book chapters. Dr. Kossentini is a senior member of the IEEE. He has served as a Vice General Chair for ICIP-2000, and he is currently an associate editor for the IEEE transactions on Image Processing and the IEEE transactions on Multimedia.
