Title: Extraction of Information from Compressed Digital Video
------
Speaker: Professor Bede Liu
------- Electrical Engineering
Princeton University
Princeton, NJ
Abstract:
---------
Moving images are becoming increasingly important in every aspect of modern
life: entertainment, education, training, scholarly research, etc. There is
already a large body of video material in repository and more material are
added to this collection at a fast pace. It is expected that much of video
material will be in compressed form.
For analog video, it is difficult to develop effective tools for search,
browsing, navigation, etc. because of its sequential or linear nature of the
media. Digital video offers the potential to overcome these limitations.
However, in comparison with text based material, very few tools have been
developed to date to make moving images a more useful information format.
A multimedia 'table of content' for a video containing images, audio, and
temporal information, would facilitate browsing of the video and navigating
in a large collection of such material. It would also help us to develop
tools to analyze the video.
One such 'table of content' is a recently introduced notion of Scene
Transition Graph (STG) which can be automatically extracted from a compressed
video. This talk will discuss the steps involved in its construction.
Biography:
----------
Bede Liu went through 5 elementary schools and 7 middle schools (names upon
request) before settling down at the Taiwan University, where he lasted full
four years, although he didn't quite make the University's varsity swimming
team. He was, however, a member of the BTU-U team-of-four that took the
championship at the First Taipei Open Bridge Tournament. He also assisted the
late Rev. Father Fang How, a noted history professor (on Sung Dynasty), in
celebrating the daily Mass at 6:30 a.m. on alternating weeks.
He did graduate work at the Polytechnic Institute of Brooklyn, under
several of the world's greatest EE professors, and collected two degrees
there. He was then hired by the Bell Laboratories. For three years, he
did very little, including what a Member of Technical Staff should be doing.
So he joined the faculty of Princeton University, and did his share of
teaching, publishing, and giving talks.
He has many good friends in the Circuits and Systems Society,
the Acoustics, Speech and Signal Processing Society, and the Information
Theory Society of IEEE. He was elected to the IEEE Board of Directors
at its centennial year, representing one of the ten Technical Divisions,
which means, among other things, that he must attend many long meetings
during those two years. At least four times a year, and each lasting one week.
Over the years, his students dragged him, kicking and screaming, through
various fields of research and forced him to learn with them.
He was recently promoted to the most senior member of his department at
Princeton where he is looking forward to many more years of being bullied by
his students and colleagues.
Professor Liu published 100 journal papers and 110 conference papers,
coauthored senior text, and edited one research volume. He obtained 5
patents with 2 more pending. His current research includes video coding
(HDTV, low bit rate), digital library and medical imaging. He supervised
46 ph.d's (including 6 joint supervisions), among whom 1/4 are Fellows of
IEEE, 1/2 are teaching at universities in U.S. and abroad. He won IEEE
Centennial Medal in 1984, IEEE Signal Processing Society Technical
Achievement Award in 1985, IEEE Circuits and Systems Society Education Award
in 1988, IEEE Video Technology Transactions Best Paper Award in 1994 and 1996,
IEEE Circuits and Systems Society Mac Van Valkenburg Award in 1997. He served
in IEEE Board of Directors (1984, 1985), as President of IEEE Circuits and
Systems Society (1982) and General Chair, IEEE International Conference on
Image Processing (1995).
