Lab Director (or Principal Investigator)

Dr. Takeshi Ikenaga received his B.E. and M.E. degrees in electrical engineering and Ph.D degree in information & computer science from Waseda University, Tokyo, Japan, in 1988, 1990, and 2002, respectively. He joined LSI Laboratories, Nippon Telegraph and Telephone Corporation (NTT) in 1990, where he had been undertaking research on the design and test methodologies for high performance ASICs, a real-time MPEG2 encoder chip set, and a highly parallel LSI & system design for image understanding processing. He is presently a professor in the system LSI field of the Graduate School of Information, Production and Systems, Waseda University. His current research interests are application SoCs and system design for image and video processing, which covers video compression (e.g. H.264/AVC, H.264/SVC, HEVC), video filter (e.g. super resolution, noise reduction), video recognition (e.g. feature point detection, object tracking) and video communication (e.g. UWB, LDPC, public key encryption). Dr. Ikenaga is a senior member of IEEE and a member of APSIPA, IEICE, IPSJ and IIEEJ. He is now serving a chair of signal processing systems: design and implementation technical committee of APSIPA.

Lab Introduction

Our laboratory is aiming for a research and development on various kinds of image information systems and related system LSIs for coming ubiquitous and ambient information society, where we can easily access any information at "anytime" and "anywhere" with "safe" and "comfortable". We think important technical fields cover wide variety of image/video recognition (object tracking, scene analysis, and so on), image/video compression (H.264, H.265, JPEG2000 and so on) and image/video communication (encryption, wireless communication and so on). We start the research from evaluation of key algorithm and then think out hardware architecture considering various factors, such as performance, low power and hardware size. Our final goal is creating a real-time embedded system or LSI in order to verify the usefulness of proposed ideas. Actually, we developed 27 LSI chips from 2004. We are promoting many national projects, such as Global COE, Core Research for Evolutional Science and Technology (CREST). We are also promoting industry academia collaborations with many companies.
