Towards Global Rate Distortion Optimization in Video Coding: Recent Developments.

Share

The past decades have witnessed great advancement of video coding techniques and their wide applications in video storage and communications, where rate-distortion optimization (RDO) plays a crucial role to maximize coding efficiency in video coding. In the current block-based hybrid video coding framework, the RDO is typically performed on the block level individually and independently, which is far from being optimal as it ignores the strong spatial-temporal dependency. However, a global RDO problem becomes so complex that the processing of each coding unit is dependent and entangled with each other due to the extensive use of spatial-temporal predictions in video coding. In the talk, I will discuss the challenges of achieving global RDO in one-pass video coding and present our recent work considering the temporal dependency on top of the video coding standards H.264/AVC and HEVC, respectively.

Biography:

Ce ZHU (M'03-SM'04-F'17) received the B.S. degree from Sichuan University, Chengdu, China, and the M.Eng and Ph.D. degrees from Southeast University, Nanjing, China, in 1989, 1992 and 1994, respectively, all in electronic and information engineering. He had been with Nanyang Technological University, Singapore, for 14 years from 1998 to 2012. He also held visiting positions at Queen Mary, University of London, U.K., in 2008, and Nagoya University, Japan, in 2011. He is currently a Professor with the University of Electronic Science and Technology of China, China.

His research interests include image/video coding, streaming and processing, 3D video, visual perception and applications. He has authored or co-authored 190+publications. He is a Fellow of the IEEE (2017, "for contributions to video coding and communications"), and a Fellow of the IET (2014).
