As more and more applications require taking pictures in various situations using battery-powered handheld devices, one of the key practical issues now is simply how to make the device run longer. Since high-capacity battery technology is not easy to achieve in a short time, algorithmic reduction of processing complexity of visual (i.e., image and video) information in a totally new direction is very interesting. In this context, we will look at the compressed sensing (CS) approach for the low complexity image/video encoder in this talk. In order to bring the compressive sensing concept down to image/video compression, we take the block-based approach and investigate the following three problems: acquisition, measurement compression, and reconstruction. We aim at a low complexity image/video encoding with a low sampling rate and simple encoding which can provide good rate-distortion performance.
Prof. Byeungwoo Jeon received the B.S. (magna cum laude) and M.S. degrees, both from the Dept. of Electronics Engineering, Seoul National Univ., Seoul, Korea, in 1985 and 1987, respectively, and the Ph.D. degree from the School of Electrical Engineering, Purdue Univ., West Lafayette, IN, USA, in 1992. He worked in the Signal Processing Laboratory, Samsung Electronics, Korea, from 1993 to 1997 for research and development of video compression algorithms, the design of digital broadcasting satellite receivers, and other MPEG-related research for multimedia applications. He served as the Project Manager of Digital TV and Broadcasting with the Korean Ministry of Information and Communications from 2004 to 2006 for supervising all digital TV-related R&D in Korea. Since 1997, he is in the School of Electronic and Electrical Engineering, Sungkyunkwan Univ. where he is currently a Professor. His research interests include multimedia signal processing, video compression, statistical pattern recognition, and remote sensing. He is a senior member of IEEE, and member of the International Society for Optics and Photonics, the Institute of Electronics Engineers of Korea, the Korean Institute of Communications and Information Sciences, and the Korean Society of Broadcast Engineers. He also serves IEEE as an associate editor for IEEE Transactions on Broadcasting since 2011. He was a recipient of the IEEK Haedong Paper Award in the Signal Processing Society, Korea, in 2005.
