Summary:
The past few years have seen an explosion in the use of digital
media. Industry is making significant investments to deliver digital
audio, image and video information to consumers and customers. A new
infrastructure of digital audio, image and video recorders and
players, on-line services and electronic commerce is rapidly being
deployed. These changes, coupled with a merging of technologies and blurring
of differences between several industries, have created new paradigms in
almost all areas of human activity including information exchange,
entertainment, education, commerce and research. In this talk, I overview
some of the benefits that have resulted from these paradigm shifts
as well as the new challenges created by the new technologies. In
particular, I will focus on the role of signal processing in making the
promises of the new technologies a reality and in solving the problems
associated with the deployment of these new technologies.
Biography:
Ahmed H Tewfik
(Fellow IEEE)
was born in Cairo, Egypt on October 21, 1960. He received his B.Sc.
degree from Cairo University, Cairo Egypt, in 1982 and his M.Sc.,
E.E. and Sc.D. degrees from the Massachusetts Institute of
Technology, Cambridge, MA, in 1984, 1985 and 1987 respectively.
Dr. Tewfik has worked at Alphatech, Inc., Burlington, MA in 1987.
He is currently the E. F. Johnson professor of Electronic
Communications with the department of Electrical Engineering at
the University of Minnesota. He served as a consultant to MTS
Systems, Inc., Eden Prairie, MN and is a regular consultant to
Rosemount, Inc., Eden Prairie, MN. His current research interests
are in signal processing for multimedia (in particular watermarking, data
hiding and content-based retrieval), low power multimedia communications,
adaptive search and data acquisition strategies for world wide web
applications, radar and dental/medical imaging and industrial measurements.
Prof. Tewfik is a Fellow of the IEEE. He is currently a Distinguished
Lecturer of the IEEE Signal Processing Society.
He was a principal lecturer at the 1995 IEEE EMBS summer school. He
was awarded the E. F. Johnson professorship of Electronic
Communications in 1993. He received a Taylor faculty development
award from the Taylor foundation in 1992 and an NSF research
initiation award in 1990. He gave a plenary lecture at the 1994 IEEE
Int. Conf. on Acoust. Speech and Signal Proc. (ICASSP'94) and an
invited tutorial on wavelets at the 1994 IEEE workshop on Time-
Frequency and Time-Scale Analysis. He was selected to be the first
Editor-in-Chief of the IEEE Signal Processing Letters in 1993. He is
a past associate editor of the IEEE Trans. on Signal Proc. and was a
guest editor of two special issue of that journal on wavelets and their
applications.
