Abstract:
|
With the availability of production tools and distribution
infrastructures,
digital video content and applications are becoming prevalent.
Researchers have been actively developing technologies for video
indexing
and summarization, in order to facilitate efficient management,
exchange,
and consumption of digital videos.
This tutorial will include two parts: (1) surveys of promising
technologies
and (2) discussion of potential applications. The survey component will
include descriptions of the building blocks of a video indexing system,
including
- shot detection and shot-based visualization interfaces, including
difference
based approaches, statistical approaches, and approaches handling
special
effects, flash, motion etc.
- video object extraction and indexing, including (semi-)automatic
object
extraction, feature extraction, and object retrieval techniques
- audio-video scene segmentation, including clustering based approaches,
memory-based approaches, multimedia fusion, and approaches using
domain-specific syntactic rules
- video summarization and skimming, including spatial summaries,
temporal
summaries, and time-compression skimming using domain-specific syntax
- event detection and classification, including learning-based event
classification (e.g., HMM, Bayesian Networks), and joint
visual-textual-audio
classification
The application component will include case studies demonstrating the
impact and challenges of the above technologies. Specifically, we
will review applications in sports, medicine, news, presentation, and
web-based search engines. Brief discussion will be given to explain the
relationships of the technologies and the newly completed MPEG-7
standard.

About the presenter:
|
Shih-Fu Chang is currently a Professor at the Department of Electrical
Engineering of Columbia University. He leads Columbia University's ADVENT industry-university
consortium and the Digital Video/Multimedia research group
(www.ee.columbia.edu/dvmm), conducting research in
multimedia indexing, adaptive coding, streaming, and authentication.
Several systems developed by his group have been widely used, including
VideoQ,
WebSEEk for image/video searching, WebClip for networked video editing,
and Sari for online image authentication watermarking.
In addition to developing new theories and algorithms, he is also
interested
in applying video technology to various domains, such as a medical video
digital
library funded by the DLI-2 initiative, a Digital News project, and
a live sports video filtering project.
Prof. Chang has been a general co-chair of ACM Multimedia Conference
2000, an
associate editor of several journals, and a consultant in several new
media
companies. He is a Distinguished Lecturer in IEEE Society of Circuits
and
Systems from 2001-2002. His group has actively participated in the
development
of MPEG-7.
He has been awarded a Navy ONR Young Investigator Award, a Faculty
Development Award from IBM, a CAREER Award from National Science
Foundation,
and three Best Paper Awards from IEEE, ACM, and SPIE in the areas of
multimedia manipulation and retrieval.
