摘要： With the emergence of compressive sensing theory, it brings new opportunities to the problems on communication and information theory. In this talk, we will first introduce our work on using compressive sensing for data gathering in large-scale wireless sensor network. It significantly improves the capacity of sensor network without increasing sense computation and communication cost. Afterward, we will propose the universal graph codes and apply them to source coding and channel coding on information theory. For source coding, we study the representation of sparse binary source and derive the new close-form formulation of graph evolution. For channel coding, we study LDPC codes and prove what the theoretical optimal LDPC code is.
简历：
Feng Wu received his B.S. degree in Electrical Engineering from XIDIAN University in 1992. He received his M.S. and Ph.D. degrees in Computer Science from Harbin Institute of Technology in 1996 and 1999, respectively. Wu joined in Microsoft Research Asia, formerly named Microsoft Research China as an Associate Researcher in 1999. He has been a researcher with Microsoft Research Asia since 2001 and is now a Senior Researcher/Research Manager.
His research interests include image and video representation, media compression and communication, as well as, computer vision and graphics. He has authored or co-authored over 150 papers published in journals like IEEE Transaction on Signal Processing, IEEE Transaction on Image Processing, IEEE Transactions on Circuits and System for Video Technology, IEEE Transactions on Multimedia and some other International Conferences and Forums, e.g., ICIP, ICME and ISCAS. As a co-author, he got the best paper award in IEEE T-CSVT 2009, PCM 2008 and SPIE VCIP 2007. Wu has been a senior member of IEEE. He serves as Technical Program co-chair on VIE 2008, PCM 2009 and VCIP 2010.
He has been an active contributor to ISO/MPEG and ITU-T standards. Some techniques have been adopted by MPEG-4 FGS, H.264/MPEG-4 AVC and H.264 SVC standard. Wu served as the chairman of China AVS video group in 2002~2004 and led the efforts on developing China AVS video standard 1.0. He has over 50 U.S. patents granted or pending in video and image coding.
