Remote visualization of volumetric images has gained importance over the past few years in medical and industrial applications. Volume visualization is a computationally intensive process, often requiring hardware acceleration to achieve a real time viewing experience. One remote visualization model that can accomplish this would transmit rendered images from a server, based on view-point requests from a client. For constrained server-client bandwidth, an efficient compression scheme is vital for transmitting high quality rendered images. In this talk, we present a new view compensation scheme that utilizes the geometric relationship between view-points to exploit the correlation between successive rendered images. The proposed method obviates motion estimation between rendered images, enabling significant reduction to the complexity of a compressor. Additionally, the view compensation scheme, in conjunction with JPEG2000 performs better than AVC, the state of the art video compression standard.
Biography
Michael Marcellin graduated summa cum laude with the B.S. degree in Electrical Engineering from San Diego State University in 1983, where he was named the most outstanding student in the College of Engineering. He received the M.S. and Ph.D. degrees in Electrical Engineering from Texas A&M University in 1985 and 1987, respectively. Since 1988, Dr. Marcellin has been with the University of Arizona, where he holds the title of Regents' Professor of Electrical and Computer Engineering, and of Optical Sciences. His research interests include digital communication and data storage systems, data compression, and signal processing. He has authored or coauthored more than two hundred publications in these areas.
Dr. Marcellin is a major contributor to JPEG2000, the emerging second-generation standard for image compression. Throughout the standardization process, he chaired the JPEG2000 Verification Model Ad Hoc Group, which was responsible for the software implementation and documentation of the JPEG2000 algorithm. He is coauthor of the book, "JPEG2000: Image compression fundamentals, standards and practice," Kluwer Academic Publishers, 2002. This book is intended to serve as a graduate level textbook on image compression fundamentals, as well as the definitive reference on JPEG2000. Dr. Marcellin served as a consultant to Digital Cinema Initiatives (DCI), a consortium of Hollywood studios, on the development of the JPEG2000 profiles for digital cinema.
Professor Marcellin is a Fellow of the IEEE, and is a member of Tau Beta Pi, Eta Kappa Nu, and Phi Kappa Phi. He is a 1992 recipient of the National Science Foundation Young Investigator Award, and a corecipient of the 1993 IEEE Signal Processing Society Senior (Best Paper) Award. He has received teaching awards from NTU (1990, 2001), IEEE/Eta Kappa Nu student sections (1997), and the University of Arizona College of Engineering (2000). In 2003, he was named the San Diego State University Distinguished Engineering Alumnus. Professor Marcellin is the recipient of the 2006 University of Arizona Technology Innovation Award. From 2001 to 2006, Dr. Marcellin was the Litton Industries John M. Leonis Professor of Engineering. He is currently the International Foundation for Telemetering Professor of Electrical and Computer Engineering at the University of Arizona.
