STANFORD PRESIDENTIAL LECTURE SERIES
on Monday, 29 November, 7:00pm
Kresge Auditorium
http://prelectur.stanford.edu/lecturers/index.html#dao
The third and final lecturer scheduled to appear in the Fall Quarter
series is Bei Dao, considered to be one of China's foremost poets. He
is also known as Zhao Zhenkai, but has used the pseudonym Bei Dao
since the late 1970s. In 1989, he was accused of helping to incite the
protests in Tiananmen Square and consequently forced into exile. He
has published numerous volumes of poetry and short stories, several of
which have been translated into English. He was also one of the
founders of Today (Jiantian), a literary magazine that provided a
venue to emerging authors and poets, including Bei Dao himself. Bei
Dao, who now lives in the U.S., has been a visiting scholar at the
International Institute and the Center for Chinese Studies. Currently,
he is in residence at the University of California Davis, and working
on a collection to be entitled "Unlock." Bei Dao, accompanied by his
translator, Eliot Weinberger, will lecture and give a reading in
Chinese and English at Stanford on November 29.

NEC Auditorium, Gates Computer Science Building, B03
SPARC64 V:
A High Performance and High Reliability 64-bit SPARC Processor
Michael C. Shebanow
HAL Computer Systems, Inc.
http://www.stanford.edu/class/ee380/Abstracts/991201.html
About the talk: SPARC64 V is HAL's Microprocessor Division's latest
generation high performance/reliability processor aimed at the
high-end commercial and technical UNIX server market.
The key design goals of SPARC64 V include high expected performance
relative to its competition (Ultrasparc 3/4, Itanium, HP8700, Compaq
21364, IBM Gigaprocessor), very high reliability (processor's ability
to detect and recover from soft errors and other failures), and
ability to perform in large-scale SMP UNIX servers (8-128 processors)
with either commercial (e.g. TPC-C/D) or technical (SPEC, scientific)
application workloads. With SPARC64 V, both HAL and Fujitsu have the
specific goal of establishing Fujitsu as a world-wide key player in
the UNIX server market.
SPARC64 V is an eight-issue superscalar, dynamically-scheduled
processor employing super-speculation as a means to reduce internal
execution latencies. SPARC64 V also employs a 1024-entry trace cache
as a means of reducing the average pipeline length to only seven
stages. For high execution performance, SPARC64 V integrates 4 integer
execution units, 2 load units, 2 store units, and dual floating-point
add-multiply units along with on-board 32KB and 256KB instruction
caches and 8KB and 512KB data caches.
A high performance external third level cache is also supported
(4MB-64MB, 16MB nominal, up to 16 GB/sec data rates), and a high speed
modified UPA bus interfaces to the system (up to 8 GB/sec data
rates). SPARC64 V also includes many reliability features, such as ECC
on all write-back caches (internal or external), parity on internal
buses, function-unit redundancy,parity/remainder checking on
arithmetic operations, etc. SPARC64 V is implemented in a 0.12
micron, 6 layer copper CMOS process, and is expected to operate at 1
GHz.
About the speaker: Michael C. Shebanow is Vice President and Chief
Technical Officer at HAL Computer Systems' Microprocessor Division. He
is also co-architect of the SPARC64 V processor. Michael received his
Ph.D. in Computer Science from UC Berkeley in 1994.
Michael's background includes 2 1/2 years at Motorola (1989-1991)
where he worked on the 88120 processor architecture, and was a member
of the PowerPC architecture committee. From 1991 through 1994, he
worked at HAL Computer Systems where he architected the SPARC64 I
processor and managed its development. From 1994 through 1997, he
worked at Cyrix Corporation on the M3 processor, both as co-architect
and project manager. Michael returned to HAL in 1997.

BROAD AREA COLLOQUIUM FOR
AI-GEOMETRY-GRAPHICS-ROBOTICS-VISION

Bayesian Analysis of Image Sequences:
Detection and tracking of Motion Boundaries
David Fleet
Xerox PARC and Queen's University
Motion analysis concerns the estimation and recognition of motion from
image sequences. It is useful for scene segmentation, estimating 3D
surface structure and camera motion, and for the detection and
tracking of objects, such as people. A long-standing problem in motion
analysis has been the detection and estimation of motion in the
neighborhoods of surface boundaries, where motion in the image is
discontinuous and occlusions cause image structure to appear or
disappear from one image to the next. Although these "motion
boundaries" are often viewed as a source of noise for current motion
estimation techniques, we can also view them as a rich source of
information about the location of surface boundaries and the depth
ordering of surfaces at these locations.
We propose a Bayesian framework for representing and estimating image
motion in terms of multiple motion models, including both smooth
motion and local motion discontinuity models. We compute the posterior
probability distribution over models and model parameters, given the
image data, using discrete samples and a particle filter for
propagating beliefs through time. In this talk I will introduce the
problem then describe our Bayesian framework, including the generative
models, the likelihood computation, the particle filter, and a mixture
model prior from which samples are drawn. I will also present some
recent experimental results.
About the Speaker: David Fleet is a research scientist at the Xerox
Palo Alto Research Center (PARC), and an Associate Professor in the
Department of Computer Science at Queen's University, Kingston,
Canada. After receiving a PhD in Computer Science from the University
of Toronto in 1991, Dr. Fleet joined the Department of Computer
Science at Queen's University, with cross-appointments to the
Departments of Psychology, and Electrical Engineering. In 1999 he
joined the Digital Video Analysis Group at Xerox PARC, where his
research is focused on motion analysis in computer vision. Dr. Fleet
was awarded an Alfred P. Sloan Research Fellowship for his research on
biological vision. In 1999 his paper with Michael Black on
probabilistic detection and tracking of motion discontinuities
received Honorable Mention for the Marr Prize at the International
Conference on Computer Vision. His research interests include computer
vision, image processing, visual perception, and visual neuroscience.
He has published research articles and one book on various topics
including the estimation of optical flow and stereoscopic disparity,
probabilistic methods in motion analysis, modeling appearance changes
in image sequences, non-Fourier motion and stereo perception, and the
neural basis of stereo vision.

CueVideo: Automated Video Indexing and
Browsing for Distributed Learning
Dragutin Petkovic
Manager, Visual Media Management
IBM Almaden
We believe that the key problems in making widespread use of video
libraries, especially in training, education and corporate
communication are:
a) costly process of manual video indexing and content preparation
from raw data in order to produce easy to search and browse media
presentations;
b) ability of users to quickly find sections of videos
they want. CueVideo project attempts to solve these problems by
automating the process of indexing and summarization of the video
content for typical education/training by providing:
a) easy to browse video summaries;
b) automated indexing using speech reco and audio/video analysis;
c) automated hyperlinking of video to related material such as foils
and text.
d) extraction of basic phrases
CueVideo combines video, audio and speech reco (IBM's ViaVoice) with
advanced IR. Our work includes close collaborating with T. J. Watson
(speech reco and IR) and Haifa (fast audio).
Bio:
Dragutin Petkovic received his B.S.E.E. and M.S.Sc. degrees from the
University of Belgrade in 1976 and 1979, respectively, and his
Ph.D. degree in Electrical Engineering from University of California,
Irvine in 1983. His thesis work was in automated detection of lung
nodules from chest radiographs.
From 1978 to 1981 he worked as a research engineer in Institute "Boris
Kidric", Vinca, Yugoslavia. In 1983 he joined IBM Almaden Research
Center, San Jose, CA, where he currently manages the Visual Media
Management Department.
QBIC (Query by Image Content) is one project Dragutin initiated and is
still involved in. Dragutin become IEEE Fellow 1998 for his work on
content based retrieval. His research interests include image analysis
and pattern recognition applied to content based search and retrieval
of images and video, large multimedia databases for education and
training, and advanced perceptual user interfaces. He is also
associate editor of International Journal of Machine Vision and
Applications (Springer-Verlag), IEEE Multimedia Magazine, and Kluwer's
Multimedia Tools and Applications Magazine.

SEMINAR ON PEOPLE, COMPUTERS, AND DESIGN
on Friday, 3 December 1999, 12:30pm to 2:00pm

Internet Based Interactive Character Design:
From Agents to Avatars
Steve DiPaola
Director of Development, Communities.com
The windows-based desktop metaphor ... Text and graphical user
interfaces ... Multimedia displays of moving images and audio
... These three concepts constitute the majority of methods we use to
communicate, to educate, to entertain with our computers and the
Internet. And yet in our daily lives we communicate and engage in a
totally different way. We talk with our friends and relatives -- we
watch their facial expressions, read into their pauses, vocal
inflections and hand gestures. This is the language, the syntax, that
we are all truly experts in: communicating and engaging interactively
with people -- with characters that emotionally engage and entertain
us through films, plays and cartoons; characters that inform and try
to influence us, such as teachers, sales people and business
colleagues; characters that have personality and spirit. There is a
real schism between the metaphors and interfaces we use with our
interactive systems and those we use in our ubiquitous life. The high
end computer animation industry now has the knowledge and techniques
to create computer animated characters that can engage an
audience. Some of this knowledge and experience has been successfully
transferred over to Internet-based characters. But with few
exceptions, character animation is still mimetic to the linear style
associated with film. We are now at a seminal point in time, where it
is becoming possible to combine the emotive and communicative
qualities of characters with the interactive, programmatic and
alternative narrative technologies of the Internet. Characters we can
talk/listen to with speech recognition/synthesis; characters who
exhibit the illusion of life and cognition via artificial
life/intelligence algorithms, information retrieval capabilities and
behavioral models. These technologies can be combined with emerging
communication and narrative metaphors such as multi-user worlds, and
interactive or participatory performances. I will discuss the
implications of these issues, as well as give a presentation of
projects that I have developed for both web-based hosts and multi-user
avatar communities.
Steve DiPaola has been involved with computer based character design
for many years starting back in 1984 when he was a senior member of
the computer animation research group at the New York Institute of
Technology. He specialized in 3D character animation R&D as well as
producing animation for film, TV and his Fine Art work. His main area
of expertise at NYIT was 3D Facial Animation and has published several
papers and book excerpts on the subject.
He is currently Development Director of Development at
Communities.com's OnLive Group, where he leads a team of artists,
architects, UI designers and musicians in designing and developing 3D
avatars and virtual spaces. OnLive's Internet-based Virtual World
software and communities allow groups of people to socialize with each
other by navigating through 3D spaces, meeting others and talking with
their own voices through emotive, lip-syncing 3D head avatars.
He co-headed the San Francisco office of Saatchi and Saatchi's
innovation arm called Darwin Digital as Creative Director. Darwin
Digital was mandated to explore state of the art new media and
interactive projects including several Internet based characters
projects.
