Brief
Bio:
Peter Robinson is Reader in Computer Technology and Deputy
Head of Department at the University of Cambridge Computer
Laboratory in England, where he leads the Rainbow Group working
on computer graphics, interaction and electronic CAD. He is
also a Fellow, Praelector and Director of Studies in Computer
Science at Gonville & Caius College where he previously studied
for a first degree in Mathematics and a PhD in Computer Science
under Neil Wiseman.
Dr Robinson's research interests are in the general area of
applied computer science. The main focus for this is human-computer
interaction, where he has been leading work for some years
on the use of video and paper as part of the user interface.
He also works on electronic design automation and, in particular,
on support for self-timed circuits.
He lectures in the Computer Science Tripos and Diploma in
Computer Science on Discrete Mathematics and VLSI Design,
with occasional lectures on Electronic CAD, Computer Graphics
and Java.
He is a Chartered Engineer and a Fellow of the British Computer
Society.
Abstract:
The increasing power and falling cost of computers, combined
with improvements in digital projectors and cameras, are making
the use of video interaction in human-computer interfaces
more popular. This talk will present two recent video interface
projects at the University of Cambridge.
People manage large amounts of information on a physical desk,
using the space to arrange different documents to facilitate
their work. The 'desk top' on a computer screen only offers
a poor approximation. The Escritoire is a desk-based interface
for a personal workstation that uses two overlapping projectors
to create a foveal display: a large display surface with a
central, high resolution region to allow detailed work. Multiple
pen input devices are calibrated to the display to allow input
with both hands. A server holds the documents and programs
while multiple clients connect to collaborate on them. [Work

Facial displays are an important channel for the expression
of emotions, and are often thought of as projections of a
person's mental state. Computer systems generally ignore this
information. Mind-reading interfaces infer users' mental states
from facial expressions, giving them a degree of emotional
intelligence. Video processing is used to track two dozen
features on the user's face. These are then interpreted as
basic action units, which are interpreted using statistical
techniques as one of six basic emotions or 18 more complex
cognitive emotions. [Work by Rana el Kaliouby] |

Brief
Bio:
Ken Perlin is a professor in the Media Research Laboratory,
within the Department of Computer Science at New York University.
He directed the NYU Center for Advanced Technology from 1994-2004.
His research interests include graphics, animation, and multimedia.
In January 2004 he was the featured artist at the Whitney
Museum of American Art. In 2002 he received the NYC Mayor's
award for excellence in Science and Technology and the Sokol
award for outstanding Science faculty at NYU. In 1997 he won
an Academy Award for Technical Achievement from the Academy
of Motion Picture Arts and Sciences for his noise and turbulence
procedural texturing techniques, which are widely used in
feature films and television. In 1991 he received a Presidential
Young Investigator Award from the National Science Foundation.
Dr. Perlin received his Ph.D. in Computer Science from New
York University in 1986, and a B.A. in theoretical mathematics
from Harvard University in 1979. He was Head of Software Development
at R/GREENBERG Associates in New York, NY from 1984 through
1987. Prior to that, from 1979 to 1984, he was the System
Architect for computer generated animation at Mathematical
Applications Group, Inc., Elmsford, NY, where the first feature
film he worked on was TRON. He has served on the Board of
Directors of the New York chapter of ACM/SIGGRAPH, and currently
serves on the Board of Directors of the New York Software
Industry Association.
Abstract:
Thanks to Moore's Law and GPU technology, real time graphics
is advancing by leaps and bounds. Much of this advance is
being driven by games. But perhaps interactive graphics can
move beyond game play. Perhaps an interactive character can
make you cry, or otherwise move you deeply, in the way you
can be moved by characters in a novel or film. This could
effect a revolution in how society perceives and uses interactive
graphics. In this talk I will show some of the steps along
the way to this revolution. |

Brief
Bio:
Dr Andre Gagalowicz is a research director at INRIA, FRANCE.
He was the creator of the first laboratory involved in image
analysis/synthesis collaboration techniques in 1984. He graduated
from Ecole Superieure d'Electricite in 1971 (engineer in Electrical
Engineering), obtained his PHD in Automatic Control from the
University of Paris XI, Orsay, in 1973, and his state doctorate
in Mathematics (doctorat d'Etat es Sciences) from the University
of Paris VI (1983). He is fluent in english, german, russian
and polish and got a bachelor degree in chinese from the University
of Paris IX, INALOCO in 1983. His research interests are in
3D approaches for computer vision, computer graphics, and
their cooperation and also in digital image processing and
pattern recognition. He received the prizes of the best scientific
communication and the best technical slide at the Eurographics'85
conference. He was awarded the second prize of the Seymour
Cray competition in 1991 and one of his papers was selected
by Computers and Graphics journal as one of the three best
publications of this journal over the last ten years. He took
part to the redaction of eight books and wrote around two
hundreds publications. He was the founder and the last chairman
of the MIRAGES international conference. The last version
of the MIRAGES conference took place at INRIA, FRANCE between
the 3rd and 5th of March 2005. This conference is exclusively
dedicated to computer vision/computer graphics collaboration
techniques.
Abstract:
I will first explain what is 3D rotoscopy and its role in
post-production applications. Then I will present the computer
vision/computer graphics strategy used to perform this task.
I will first briefly present the case of rigid objects where
the strategy appears clearly. I will then proceed to the case
of articulated objects and especially to the case of a full
human body tracking (when garments are rather tight). I will
present some results related to the tracking of professional
golfers. Finally, I will give some results of face tracking
which is a case of deformable objects. I will conclude with
a presentation of other possible applications of the research
done at the MIRAGES laboratory at INRIA Rocquencourt. |
