ABSTRACT: 

We present state-of-the-art techniques for processing of video contents
for seamless video searching and delivery over Internet and wireless networks.
In particular, we describe a production quality prototype system, iVIEW,
which is an intelligent digital video content management system for video
information processing, indexing, searching, visualization and presentation.
We envision multiple information streams (newswires, television and radio
broadcasts, archival collections) arriving in different formats, which
require segmentation, indexing, categorization, retrieval, summarization,
and on-demand integrated presentation.  The iVIEW system thus unifies
several previously disjoint areas of investigation, including:
speaker-independent, connected speech recognition; video text detection,
localization and extraction; on-demand video summarization; image processing;
automatic capture and processing of multimedia information; and intelligent
aids to the creation and reuse of multimedia information.  XML is engaged
for system interoperability, multimedia data exchange, and information
integration of digital video library contents.  In addition to integrating
known video processing schemes, iVIEW embraces innovative algorithms in our
research projects for video text processing and logo detection, and mobile
delivery.  The techniques we developed enable information access from Web,
PDA and mobile devices over wireless networks, which will be demonstrated
during the talk.


BIOGRAPHY: 

Michael R. Lyu received the B.S. (1981) in electrical engineering from
National Taiwan University, the M.S. (1985) in computer engineering from
University of California, Santa Barbara, and the Ph.D. (1988) in computer
science from University of California, Los Angeles. He is a Professor at
the Computer Science and Engineering Department of the Chinese University
of Hong Kong. He worked at the Jet Propulsion Laboratory, Bellcore
(now Telcordia) and Bell Labs, and taught at the University of Iowa.
His research interests include software reliability engineering,
distributed systems, image and video processing, fault-tolerant computing,
web technologies, web-based multimedia systems, and wireless communications.
He has published over 140 papers in these areas. He is the editor for two
book volumes: Software Fault Tolerance, published by Wiley in 1995 and the
Handbook of Software Reliability Engineering, published by IEEE and
McGraw-Hill in 1996. He has been an associated editor of IEEE Transactions
on Reliability, IEEE Transactions on Knowledge and Data Engineering,
and Journal of Information Science and Engineering.
