Stereo Algorithms and Representations for
Image-Based Rendering
Richard Szeliski
Vision Technology Group
Microsoft Research
In this talk, I will review a number of stereo matching algorithms and
representations I have developed in the last few years. The talk
focuses on techniques that are especially well suited for image-based
rendering applications such as novel view generation and the mixing of
live imagery with synthetic computer graphics. I will begin by
reviewing some recent approaches to the classic problem of recovering
a depth map from two or more images. I will then describe a number of
newer representations (and their associated reconstruction
algorithms), including volumetric representations, layered
plane-plus-parallax representations, and multiple depth maps. Each of
these techniques has its own strengths and weaknesses, which I will
address.
About the Speaker:
Richard Szeliski is a Senior Researcher in the Vision Technology Group
at Microsoft Research, where he is pursuing research in 3-D computer
vision, video scene analysis, and image-based rendering. His current
focus is on constructing photorealistic 3D scene models from multiple
images and video. He received a Ph. D. degree in Computer Science from
Carnegie Mellon University, Pittsburgh, in 1988. He joined Microsoft
Research in 1995. Prior to Microsoft, he worked at Bell-Northern
Research, Schlumberger Palo Alto Research, the Artificial Intelligence
Center of SRI International, and the Cambridge Research Lab of Digital
Equipment Corporation.
Dr. Szeliski has published over 60 research papers in computer vision,
computer graphics, medical imaging, neural nets, and parallel
numerical algorithms, as well as the book Bayesian Modeling of
Uncertainty in Low-Level Vision. He served as co-chair of the SPIE
Conferences on Geometric Methods in Computer Vision, the 1999 Vision
Algorithms Workshop, and as an Associate Editor of the IEEE
Transactions on Pattern Analysis and Machine Intelligence.

Transmeta's Crusoe: A Low-Power x86-Compatible
Microprocessor Built with Software
David Ditzel
CEO, Transmeta Corp.
Transmeta has recently introduced a new microprocessor family named
Crusoe. Crusoe in unique in that it is the first microprocessor whose
instruction set is implemented entirely with software. Software
dynamically translates any x86 software to an underlying VLIW
processor that contains special hardware support for dynamic
translation. The net result is a processor that is fully compatible
with all x86 software, has high performance, but uses very low power
consumption (about 1 watt). The first two Crusoe processors are the
400 MHz TM3120 for mobile internet devices using Mobile Linux, and the
700 MHz TM5400 for traditional notebook computers running Windows. A
new power management mode called LongRun will be discussed, that can
dynamically adjust the processor frequency and voltage on the fly to
minimize power consumption for mobile computer systems.
About the speaker:
Dave Ditzel is Chief Executive Officer and a founder of Transmeta
Corporation. He is a long term microprocessor designer, having worked
on over 20 different processor designs, prior to Transmeta he was
chief technical officer for Sun Microelectronics on their SPARC
processors. He co-authored "The Case for the Reduced Instruction Set
Computer" in 1980 and has published over 30 papers in the field of
advanced computer design.

Designing a Consumer Experience
Bill Cockayne
Co-Founder, Scout Electromedia
How important is design in a startup environment? Bill Cockayne will
share one perspective, based on his current involvement with an
exciting new entrepreneurial venture, Scout Electromedia. In the
course of designing an artifact, a service, and a company, Bill and
his colleagues focused first on an issue that would affect all three
of these domains: the consumer experience. Scout Electromedia started
with the question, "What does the consumer want a wireless experience
to be?" Despite the bad grammar, Scout has spent the past year
researching, designing, and building a new wireless experience. The
firm created this consumer experience created using a team focusing on
product design, HCI, ethnography, software, hardware, and a myriad of
other skills. As the wireless space evolves, Scout is intent on
listening to consumers in order to design wireless products that
provide simple, intuitive, and valuable experiences.
Bill Cockayne is one of the founders of Scout Electromedia, which
designs and builds state-of-the-art wireless devices. In his position,
Bill develops and oversees the strategic technological development of
the company's wireless products. Mr. Cockayne previously served as a
research scientist at DaimlerChrysler leading a team working on
Pervasive Computing, with a focus on consumer products, user needs and
software and hardware interfaces. Prior to joining DaimlerBenz,
Mr. Cockayne held multiple positions at Apple Computer and was a
research scientist for the U.S. Navy. He holds a Bachelor of
Mechanical Engineering, a Masters of Science in Computer Science, and
is currently on leave from the Ph.D. program at Stanford University.

The Good, the Bad and the Outrageous:
Theories of Language Evolution and their
Implications for Linguistic Nativism
Fiona Cowie
Division of Humanities and Social Sciences,
California Institute of Technology
Chomskyan nativism about language acquisition apparently commits its
proponents to telling an evolutionary story about the origins of the
human language faculty. Chomsky's own scruples about this enterprise
notwithstanding, a variety of theories as to the adaptive significance
of language have been proposed. In this talk, I will sketch some of
these theories, examine their merits, and draw some broader morals for
the Chomskyan enterprise from their successes and failures.

10 Years on 2 Wheels":
A Photographer's Journey Around the World
Helge Pedersen
Globeriders
For more than 10 years, Norwegian-born Helge Pedersen and Olga, his
sturdy BMW motorcycle, traveled vagabond style - across six
continents, through 77 countries, and over 250,000 miles, more than
ten times the actual distance around the world. Helge's mode of
transportation was very diversified: motorcycle, ship, camel,
elephant, canoe and on foot. His usually pleasant encounters with
foreign cultures and peoples taught Pedersen to view the world in a
different way. He also had to endure some hardships along the way:
malaria and corruption in postcolonial Africa; severe hunger in
southern Argentina; imprisonment in Somalia (and again in North
Yemen); broken bones and infection in Colombia; and expulsion from
Japan. He became adept at crossing deserts and jungles, changing money
on the black market, and curing dysentery. Helge selected his very
best pictures from his vast library and combined them with regional
music and live narration to bring you a view of the life of one of the
great Norwegian explorers of this century.
Helge Pedersen is a globetrotter, adventurer, photographer and
journalist. He has photographed every corner of the globe, been
interviewed by radio and TV on every continent and published hundreds
of articles in newspapers and magazines worldwide. He is also the
author of the new book, "10 Years on 2 Wheels", an unusual and
exciting travel story - the history of a wanderer with an address that
reads simply, The World.

Learning to Drive
Jeffrey Forbes
Computer Science Division, UC Berkeley
Autonomous vehicle control presents artificial intelligence with
significant challenges. In driving, there is rarely a known optimal
trajectory, rather the goal is to maximize general performance
according to a given set of factors. Reinforcement learning is one
method whereby the agent successively improves control policies
through experience and feedback (i.e., reward) from the system.
Reinforcement learning techniques have shown some promise in solving
complex control problems. However, these methods sometimes fall short
in environments with continuous state and action spaces, such as
driving. This talk presents a method for learning and maintaining a
value function approximation using instance-based learning. I propose
a hierarchical model-based solution integrating a number of new
methods from reinforcement learning to address vehicle control. The
algorithm is effective on canonical control domains as well as more
complex driving tasks.

Special Effects
Various Speakers
From Vaucanson's mechanical duck to the dinosaurs of Jurassic Park;
from the thrilling space of Italian Renaissance scenografia to the
deep space settings of Star Wars; from the advanced hydraulics feeding
the fountains at Versailles to the computer-controlled servo
mechanisms of Disneyland; from the deus ex machina of classical
theater to the mother-ship of Close Encounters, high technology has
long been used to generate--amidst a world of ordinary
experience--effects of the magical, the spectacular, and the
marvelous. Although "special effects" is a technical term for the
manipulation of filmed images, this colloquium proposes to use it more
generally, as a way of naming the particular intersection of
technology and spectacle that has produced throughout history a
parallel world of unusual or heightened experience.
What is the nature of this intersection? What can we learn from its
history? Because this other reality seems to be increasingly a place
of business rather than entertainment, we might also ask if spectacle
has reframed the limits of the public sphere. These are some of the
general questions we hope this colloquium will address.
Consideration of "special effects" might begin with a history of its
means, goals, and material techniques of bedazzlement and the
mechanical marvelous: specific technologies (such as robotics,
mechanical illusions, and animation) or the use of technology in the
production of public spectacle (from traditional theater, dance,
visual arts and music to contemporary examples of film, theme parks,
and multi-media).
These considerations lead naturally to issues of specialized technical
knowledge and research in such areas as interface design,
computer-aided product design (CAD) and themed architectures. What
drives contemporary research in the engineering labs where the
hardware and software of tomorrow are being developed? Do technical
researchers reflect on how previous discoveries have been put to use?
on their societal effects? on their role as inventors and innovators?
During the Cold War it was often said that the designers and
fabricators of nuclear weapons had become a new technical elite
serving the national interest: does that hold today for the engineers
of chip makers and software companies serving private enterprise?
All too often, discussion of high technology spectacle remains
circumscribed within the rich, so-called "advanced" cultures where it
is most prevalent. But much of the media content made in "rich"
cultures is disseminated in "poor" cultures around the world. Does the
meaning of television content change when a single receiver is shared
by many people, or when a single program airs globally? Does Internet
content mean differently when a single computer serves a whole school
or district? These are questions that sociologists and anthropologists
might ask when discussing globalized "special effects."
Finally, if "special effects" have served to mount public spectacles
of the marvelous, the direction of current technological research--the
search, for example, for increased bandwidth, faster processors,
smaller and cheaper circuitry--fosters a privatization of spectacle
never before imagined. Many of us already command on our desktop the
machinery for physically isolated experiences in which we can
virtually coexist with others dispersed throughout the world. Is this
the end of public spectacle as we know it? The emergence of a mass
culture without a mass? If so, how should we name it?
Reading The Wizard of Oz as a parable of the power of "special
effects," we might recall that even if the Wizard was a fraud, Dorothy
and her friends were moved to action by his presence. Self-awareness
followed unveiling of the wizard's machinery. Is such an unveiling
possible today, or have we become so "immersed" (to borrow a word from
digital studies) that we can no longer step back and judge? Must
technology always be unveiled, or can reflection and critical
consciousness accompany spectacular immersion? Is the user always--in
the phraseology of Star Trek--"assimilated" by advanced technology, or
can the marvelous become a tool for knowledge and experience?
In short, is there an ethics for "special effects" or do they simply
float on the surface of culture?

In Support of Multimedia Conversations
Greg Wolff
Ricoh Silicon Valley
This presentation describes a set of research prototypes designed to
improve the effectiveness of computer mediated communication. Most
electronic communication today lacks the richness of face-to-face
interaction. Email users quickly learn about the misunderstandings
that can occur with humorous or sarcastic messages (notwithstanding
the familiar "smiley-face" emoticon :-) and even experienced
correspondents have difficulty conveying the proper urgency or
IMPORTANCE of a message. In addition to the emotional content,
face-to-face communication also provides a shared context that allows
participants to easily reference topics of discussion. Speakers
naturally point to images or pick out particular lines from a
spreadsheet they may be talking about. Such actions have no
counterparts in existing electronic messaging systems.
Our prototypes address the deficiencies of electronic communication
through a number of novel human-computer interaction techniques that
use naturally recorded speech to convey emotional cues and provide a
context for referring to photos, documents, and other multimedia
objects. The portable "StoryTrack" device, acts as a kind of digital
photo album that explicitly supports the creation of stories or
narratives illustrated by the digital photos. Another prototype runs
in a more standard application environment and uses a "point & talk"
interaction model for easily composing and viewing multimedia
messages. Preliminary usage results will be presented that demonstrate
the effectiveness of these designs for particular types of
conversations.
Greg Wolff leads the information appliances research group at Ricoh
Silicon Valley. After receiving degrees in Cognitive Science from MIT
(BS) and Carnegie Mellon (MS), Greg developed one of the first WYSIWYG
hypertext markup language authoring tools in 1989 while at IBM's Human
Factors lab. At Ricoh, he has made contributions to the field of
machine learning and automatic speech reading. Current interests
include an open source project that will enable non-programmers to
develop Web applications and methods for enriching computer mediated
communication.

Lessons from Giant-Scale Services
Eric A. Brewer
UC Berkeley & Inktomi
The last five years has seen an incredible rise in the use of
infrastructure services; Yahoo! has over 400M page views per day,
Inktomi handles more than 1B searches per month, and AOL users visit
over 4B pages per day through AOL's caching infrastructure. These are
giant-scale services and they represent the broad movement of
capabilities into the infrastructure. This new class of systems
present extreme challenges for scalability, availability, and online
evolution. In this talk, I attempt to define this space, show how some
of the problems have been solved, and provide some new ways to think
about these problems.
About the speaker:
Dr. Brewer is a professor at UC Berkeley, where he focuses on Internet
infrastructure, security, and mobile computing. In 1996, he co-founded
Inktomi, which provides scalable applications for the Internet,

Natural Selection and Wason's `Selection' Task:
Is Evolutionary Psychology an Empirical Activity?
Keith Stenning
Director, Human Communication Research Centre
University of Edinburgh
I will talk about some recent work with Michiel van Lambalgen on
conditional reasoning in Wason's selection task. The dominant theory
of the most discussed `content effect' in this task is an
`evolutionary psychology explanation' due to Cosmides. I will present
some analysis, along with some tutorial dialogue evidence of a novel
kind, which reveals how little empirical curiosity has been shown
toward both the task itself, and the nature of this particular
evolutionary theory.
More generally, `rational analysis' theories (Oaksford & Chater) of
the task are also shown to be deficient in their attention to meaning.
Our argument is that the psychology of reasoning cannot afford to
ignore theories of semantics of natural language, and could be greatly
empirically enriched if semantic insights were allowed to guide their
investigations.

Dynamic Network Measurement Using Active Networks
Geoffrey H. Kuenning
Harvey Mudd College
Internet measurement has always been a difficult task, due to the
necessity for collecting data at multiple locations. Active networks,
and the active network backbone (ABONE) in particular, provide new
capabilities that can support much more powerful and flexible
measurements than have previously been practical. We describe the
design of a measurement system that takes advantage of this new
infrastructure to collect previously unavailable data, and present the
results of preliminary measurements using the system.
About the speaker:
Geoffrey H. Kuenning is an assistant professor of computer science at
Harvey Mudd College in Claremont, California. His research interests
