by C. A. Gonzales, H. Yeo and C. J. Kuo.

Biographical sketches of authors

Cesar A. Gonzales   IBM Thomas J. Watson Research Center, Yorktown Heights, New York 10598 (butron@us.ibm.com). Dr. Gonzales is an IBM Fellow, Senior Manager for Multimedia Technologies at the IBM Thomas J. Watson Research Center, and manager of the development organization of the IBM Digital Video Products Group. He is an expert in image and video processing and compression; his experience spans the development of algorithms, chip and system architectures, and multimedia applications. He is a co-inventor of various still-frame and motion video compression techniques that IBM contributed to the JPEG and MPEG international standards. He is the author of a number of patents and publications related to these techniques. While at IBM, he has received multiple Outstanding Achievement awards, including a Corporate-level award for his contributions to IBM's MPEG products. In June 1998 Dr. Gonzales was named an IBM Fellow. He was also elected to serve in IBM's Academy of Technology, and has twice been named Master Inventor for his contributions to IBM's patent portfolio. Prior to joining IBM, Dr. Gonzales worked on radar signal processing and physics of the ionosphere at the Arecibo Observatory in Puerto Rico. Dr. Gonzales is a Senior Member of the IEEE. He has served as an Associate Editor of the IEEE Transactions for Circuits and Systems for Video Technology. He has also served as the head of the U.S. delegation in the MPEG committee of the International Standards Organization. Dr. Gonzales received his B.S. and engineering degrees from the National University of Engineering (UNI) in Peru and his Ph.D. from Cornell University, all in electrical engineering.

Hangu Yeo   IBM Research Division, Thomas J. Watson Research Center, P.O. Box 218, Yorktown Heights, New York 10598 (hangu@us.ibm.com). Dr. Yeo is a Postdoctoral Fellow in the Multimedia Technologies Department at the IBM Thomas J. Watson Research Center. He received his B.S. degree in electronic engineering from Yonsei University, Seoul, Korea, his M.S. degree in electrical engineering from Columbia University, and his Ph.D. degree in electrical and computer engineering from the University of Wisconsin, Madison. From 1990 to 1992, he worked as a computer assistant at the Ministry of National Defense in Seoul, Korea. His current research interests include video/image compression algorithms, design of VLSI architectures for video and image processing, and advanced set-top-box application development.

Chung J. Kuo   Graduate Institute of Communication Engineering, National Chung Cheng University, Chaiyi, Taiwan 62107 (kuo@ee.ccu.edu.tw). Dr. Kuo received the B.S. and M.S. degrees in power mechanical engineering from National Tsing Hua University, Taiwan, in 1982 and 1984, respectively, and the Ph.D. degree in electrical engineering from Michigan State University (MSU) in 1990. He joined the Electrical Engineering Department of National Chung Cheng University (NCCU) in 1990 as an associate professor, becoming a full professor in 1996. He is now the chairman of the Graduate Institute of Communication Engineering of NCCU. Dr. Kuo was a visiting scientist at the Opto-Electronics & System Laboratory, Industrial Technology Research Institute, in 1991 and at the IBM Thomas J. Watson Research Center from 1997 to 1998. He has been a consultant to several international and local companies, and is also an adjunct professor at National Cheng Kung University. Dr. Kuo has interests in image/video signal processing, VLSI signal processing, and optical information processing/computing. He is the Director of the Signal and Media (SAM) Laboratories at NCCU. Dr. Kuo received the Outstanding Research Award from National Chung Cheng University in 1998, the Overseas Research Fellowship from the National Science Council (NSC) in 1997, the Outstanding Research Award from the College of Engineering, NCCU, in 1997, the Medal of Honor from NCCU in 1995, the Research Award from NSC every year since 1991, the Best Engineering Paper Award from Taiwan's Computer Society in 1991, an Electrical Engineering Fellowship from MSU in 1989, and the Outstanding Academic Achievement Award from MSU in 1987. He was a guest editor for two special sections of Optical Engineering and 3D Holographic Imaging (to be published by John Wiley and Sons) and has been an invited speaker and program committee chairman or member for several international/local conferences. He also serves as an Associate Editor of IEEE Signal Processing Magazine and as President of the Taiwan chapter of SPIE. Dr. Kuo is a member of Phi Kappa Phi, Phi Beta Delta, IEEE, OSA, and SPIE; he is listed in Who's Who in the World.
