ABSTRACT:
Digital compression of video has made a dramatic impact in the video
communication domain. Existing compression standards such as MPEG-2
and MPEG-4 have been instrumental for the success of many video
applications. Such applications include Digital Video Broadcast
(DVB), DVD, High Definition DVD, digital camcorders and digital video
on the web (i.e. YouTube).
The prime goal in the compression research community is to further
squeeze the bitrate of video data for storage and transmission. In
recent years more and more research concentrated on inventing and
applying sophisticated Image Processing/Computer Vision algorithms to
the compression domain. As such the field of video compression seems
to be progressing from a primarily stochastic-based pixel approach
towards a content- and region-based approach. In my talk I will give
an overview about work conducted at TU Berlin in this exciting and
promising field.
BIOGRAPHY OF SPEAKER:
Thomas Sikora is professor and director of the Communication Systems
Department at Technical University Berlin, Germany.
He received the Dipl.-Ing. degree and Dr.-Ing. degree in electrical
engineering from Bremen University, Germany, in 1985 and 1989
respectively. In 1990 he joined Siemens Ltd. and Monash University,
Melbourne, Australia, as a project leader responsible for video
compression research activities in the Australian "Universal Broadband
Video Codec" consortium. Between 1994 and 2001 he was the director
of the "Interactive Media" Department at Heinrich-Hertz-Institute (HHI)
Berlin GmbH, Germany.
Dr. Sikora has published more than 150 papers related to audio and
video processing. He edited and co-authored three books in this area,
incl. "MPEG-7 Content Description Interface", Wiley 2002 and "MPEG-7
Audio and Beyond", Wiley 2006. He has been involved in international
ITU and ISO standardization activities as well as in several European
research activities for a number of years. As the chairman of the
ISO-MPEG video group (Moving Picture Experts Group), he was
responsible for the development and standardization of the MPEG-4
and MPEG-7 video algorithms. Dr. Sikora is appointed as Research Chair
for the VISNET and 3DTV European Networks of Excellence. He frequently
works as an industry consultant on issues related to interactive
digital audio and video. He is an appointed member of the Advisory
and Supervisory board of a number of German companies and
international research organizations.
Dr. Sikora is recipient of the 1996 German ITG award (German Society
for Information Technology). Between 1998 and 2002 he was an Associate
Editor for the IEEE Signal Processing Magazine. He currently serves
as an Advisory Editor for the EURASIP Signal Processing: Image
Communication journal and as Associate Editor for EURASIP Signal
Processing journal. Dr. Sikora was the Editor-in-Chief of the IEEE
Transactions on Circuits and Systems for Video Technology between
2002 and 2006. He is a member of ITG and a senior member of IEEE.
