Biography:
Huifang Sun received his B.Sc. degree from Harbin Engineering Institute, Harbin, China in 1967, and his Ph.D. from University of Ottawa, Canada, in 1986. He was an Associate Professor at Fairleigh Dickinson University before moving to Sarnoff Research Laboratory in 1990, where he was Technology Leader of Digital Video Communication. He joined Sarnoff Lab as a member of technical staff and was promoted to Technology Leader of Digital Video Communication later. In 1995, he joined Mitsubishi Electric Research Laboratories (MERL) as Senior Principal Technical Staff and was promoted as Vice President and Fellow of MERL in 2003. His research interests include digital video/image compression and digital communication. He has coauthored two books and more than 150 Journal/and conference papers. He holds 48 US patents. He received Technical Achievement Award in 1994 at Sarnoff Lab. He received the best paper award of 1992 IEEE Transaction on Consumer Electronics, the best paper award of 1996 ICCE and the best paper award of 2003 IEEE Transaction on CSVT. He is now an Associate Editor for IEEE Transaction on Circuits and Systems for Video Technology and was the Chair of Visual Processing Technical Committee of IEEE Circuits and System Society. He is an IEEE Fellow.
HEVC
High Efficiency Video Coding (HEVC) is a proposed video compression standard, a successor to H.264/MPEG-4 AVC (Advanced Video Coding), currently under joint development by the ISO/IEC Moving Picture Experts Group (MPEG) and ITU-T Video Coding Experts Group (VCEG). MPEG and VCEG have established a Joint Collaborative Team on Video Coding(JCT-VC) to develop the proposed HEVC standard.
HEVC aims to substantially improve coding efficiency compared to AVC High Profile, i.e. reduce bitrate requirements by half with comparable image quality, probably at the expense of increased computational complexity. Depending on the application requirements, HEVC should be able to trade off computational complexity, compression rate, robustness to errors and processing delay time.
HEVC is targeted at next-generation HDTV displays and content capture systems which feature progressive scanned frame rates and display resolutions from QVGA (320x240) up to1080p and Ultra HDTV (7680x4320), as well as improved picture quality in terms of noise level, color gamut and dynamic range.
MVC/3DV
3D Video is a standard that targets serving a variety of 3D displays. It is the first phase of FTV (free-viewpoint TV), which is a new framework that includes a coded representation for multiview video and depth information to support the generation of high-quality intermediate views at the receiver. This enables free viewpoint functionality and view generation for auto-multiscopic displays.FTV system transmits multiview video with depth information. The content may be produced in a number of ways, e.g., with multi-camera setup, depth cameras or 2D/3D conversion processes. At the receiver, depth-image-based rendering could be performed to project the signal to various types of displays.
