Subject: Info wanted about 3D reconstruction
Dear Colleagues,
I just begin studying 2D and 3D image reconstruction and am particularly
interested in cone-beam algorithms. I would be deeply grateful should you
recommend some papers (specially good review papers) to me.
Also, It is said that there are a lot of public domain software on the network.
People can get the software using FTP (File Transform Protol). Does anyone
know such kind of stuff for image reconstruction in C?
Thank you very much! Best wishes.
Sincerely yours,
Wang, Ge

Subject: Looking for a frame grabber board (MacIIx)
Hello everybody,
We are looking for a frame grabber board (color), for capturing,
processing and displaying color images on a Macintosh IIx.
The main features would be
- "real-time" capture from color video cameras and VCRs
(grab speed of 1/25s or more).
- Multiple input connections (PAL).
- "genLock" output (CCIR RGB, PAL 50Hz preferred).
- High pixel resolution (something >= 768x512).
- Graphic/text overlay.
- Supported by TIFF24-compatible softwares packages (Studio/8,
PhotoShop, ..).
Any suggestions, proposals, comments, experiences, criticisms,
ideas and invitations will receive a warm welcome !

Subject: Post-Doctoral Research Positions
UNIVERSITY OF MINNESOTA
POST-DOCTORAL RESEARCH POSITIONS
Two research positions available to study the linkages between the
initial stages of human perception and later recognition. The
research uses psychophysical and computational methods to understand
these problems.
Applicants must have a Ph.D. Background in computer modeling,
psychoacoustics, visual psychophysics, perception, or supercomputers
is highly desirable. Applicants capable of forging links between
audition and vision will be given consideration. The research will
be conducted at the Center for the Analyses of Perceptual
Representations (CAPER) at the University of Minnesota . This Center
encompasses four vision laboratories and one hearing laboratory in
the Psychology and Computer Science departments, and includes ample
facilities for simulation and experimental studies. Center faculty
members are: Irving Biederman, Gordon Legge, Neal Viemeister, William
Thompson, and Daniel Kersten. Salary level: $26,000 to $32,000
depending on the candidate's qualifications and experience.
Appointment is a 100% time, 12-month appointment as post-doctoral
fellow. (Appointment may be renewable, contingent on satisfactory
performance and AFOSR funding.) Starting date is July 1, 1990 or as
soon as possible.
Candidates should submit a vita, three letters of reference,
representative reprints and preprints, and a statement of long-term
research interests to:
Professor Irving Biederman,
Department of Psychology,
University of Minnesota,
75 East River Road,
Minneapolis, Minnesota, 55455.
Applications must be received by June 15, 1990.
The University of Minnesota is an equal opportunity educator and
employer and specifically invites and encourages applications from
women and minorities.

Subject: Research Associate Position In Robot Vision
UNIVERSITY OF TORONTO
RESEARCH ASSOCIATE IN ROBOT VISION
The Government of Canada has established a Network of Centres
of Excellence named IRIS (Institute for Robotics and Intelligent
Systems), with one of its projects ("Active Vision for Mobile
Robots") based in the Department of Computer Science at the
University of Toronto. A research associate position is available,
funded by this project, with funding guaranteed for up to four years.
The successful applicant must hold a PhD in Computer Science or
Electrical Engineering with specialty in areas related to robot vision,
and must possess a strong research record. Experience with stereo-vision
robot heads would be an important asset. Ideal candidates will have
broad interests and talents across such areas as biological models
of vision and motor control, computational vision and image understanding,
attention and active perception, robot navigation, and planning.
Applications should be sent by May 21, 1990 to:-
Professor Derek G. Corneil, Chairman
Department of Computer Science
University of Toronto
Toronto, Ontario
M5S 1A4, Canada.
In accordance with Canadian Immigration regulations, priority will be
given to Canadian citizens and permanent residents of Canada.
The University of Toronto encourages both women and men to apply for
positions.

Hi,
I am seeking for a researcher position, Area= Computer Vision, Pattern
Recognition and Artificial Intelligence.
I am, for the time being visiting scholar for a post-doc at RPI
in the RAL lab.
I will be available (and jobless) next July.
I would like to find a Job in either USA, Canada, France (I speak fluently
french and was graduated there) or UK.
My resume will be sent on request.
Thanks a lot

Subject: Neural Network Chips
There are several researchers who are using analog VLSI in vision
research, e.g. Carver Mead at CalTech comes to mind. I thought
the posting might also identify others.
I am interested in learning what experiences people have had using
neural network chips. In an article that Colin Johnson did for PC
AI's January/February 1990 issue, he listed the information given
below about a number of NN chips (I've rearranged it in
alphabetical order by company name). This list is undoubtedly
incomplete (no efforts at universities and industrial research
laboratories are listed, for example) and may have inaccuracies in
it.
Such a list would be more useful if it would contain the name,
address, phone number, FAX number, and electronic mail address of
a contact person at each company would be identified.
Information about the hardware and software support (interface and
coprocessor boards, prototype development kits, simulators,
development software, etc.) is missing.
Additionally, pointers to researchers who are planning to or have
actually been using these or similar chips would be extremely
useful. I am interested in finding out the range of intended
applications.
Could you please send me:
a) updates and corrections to the list
b) company contact information
c) hardware and software support information
d) information about plans to use or experiences with having used
any of these chips (or chips that are not listed)
In a few weeks, if I get a sufficient response, I will resubmit an
enhanced listing of this information.
Thanks,
Bruce Shriver (shriver@usl.edu)
