Subject: Chevreul illusion
Can someone explain what is the Chevreul illusion seen in a luminance
staircase composed of two step edges? References appreciated. Thanks.

Subject: Stereo Sequence Wanted
We are trying to create a stereo sequence of an indoor scene with a camera
mounted on a robot arm. But we have encountered some problems due to the
calibration of the system. We wonder if anyone out there has such stereo
sequences or the like. The point is that we need the necessary (calibration)
data in order to reconstruct the 3D scene. Does anyone have or know such data?
If you do, please let us know. Any help is appreciated very much.
(The data is going to be used in a joined ESPRIT project)

Subject: Pointers to image archives
I am looking for pointers to existing archives for intensity/range/
stereo/motion images. I would also need information about the
availability of these images to outside users. I can summarize the
replies and post it to the net.

Subject: Image database
Hi,
I am looking for a database of 2-D shape (preferably industrial
shapes) to use in a shape recognition system that I am
currently implementing. I would appreciate if anybody
out there could give me one, or give me pointers as to where
I could find them.
Thanx in advance,

Subject: WANTED: image processing/pattern recognition job
Summary: German hunting jobs in Edinburgh
Organization: AIAI, University of Edinburgh, Scotland
A German lad without net-access asked me for help so here goes:
He is coming to Edinburgh in August 1990 and he would like to
start working in Edinburgh around then.
By August he will have a German degree in Computer Science.
His main interests and experiences (from Summer jobs etc.)
are in the field of image processing and pattern recognition.
If you know or hear of any vacancies I (and he) would be
grateful if you could let me know.
Thanks in advance
Jussi.

Subject: Fulbright Lecturer/Researcher Position
The Computer Vision Group at the University of Oulu, Finland, is engaged in
research into industrial machine vision, investigating problems
associated with robot vision, visual inspection and parallel vision
systems. With a staff of about 15, it is the largest group of its kind
in Finland.
The Group requests for a Fulbright lecturer/researcher scholar for one
semester during the academic year 1991-92 in the field of computer vision.
The scholar should participate in collaborative research and to teach
an advanced post-graduate course in computer vision. The scholar
should be a U.S. citizen and have a Ph.D with some years of experience
in computer vision.
The research collaboration can be in any of our interest areas,
including computer vision algorithms, vision for intelligent robots,
parallel algorithms and architectures for vision, or automated visual
inspection.
The students of the computer vision course will have at least an MSEE
degree with some experience in computer vision research. The course
will have 2 classroom hours per week. The students' comprehension
level in English is good. An estimated size of the class is 15.
The library of the Department of Electrical Engineering has all
major journals and a large number of books and conference proceedings
in the field of computer vision. The computer facilities of the
Computer Vision Group include several SUN-3 workstations, a Symbolics
3645 and IBM PC's. A dedicated image analysis system, consisting of
boards manufactured by Datacube, Inc., is used for high speed analysis
tasks. A multiprocessor system NTP 1000 based on transputers is used
for studying the problems of parallel processing. Shortly the facilities
will also include an industrial robot equipped with a CCD camera
and a range image sensor.
The Group provides office space, access to computer facilities and some
support from graduate assistants for the scholar. In addition to the
grant provided by the Fulbright program, an additional salary of at
least US$ 2000/month will be arranged from our research funds.
The University of Oulu also provides housing for the scholar.
The Council for International Exchange of Scholars will advertise the
position in the "Fulbright Scholar Program. Faculty Grants. 1991-92."
This booklet will be distributed to all American colleges and
universities in March/April 1990.
The application period for the grant will end on September 15, 1990.

Subject: CALL FOR PARTICIPATION: AAAI-90 Workshop on Qualitative Vision
Sunday, July 29 1990 Boston, Massachusetts
Qualitative descriptions of the visual environment are receiving
greater interest in the computer vision community. This recent
increase in interest is partly due to the difficulties that often
arise in the practical application of more quantitative methods.
These quantitative approaches tend to be computationally expensive,
complex and brittle. They require constraints which limit generality.
Moreover inaccuracies in the input data do not often justify such
precise methods. Alternatively, physical constraints imposed by
application domains such as mobile robotics and real-time visual
perception have prompted the exploration of qualitative mechanisms
which require less computation, have better response time, focus on
salient and relevant aspects of the environment, and use enviromental
constraints more effectively.
The one-day AAAI-90 Workshop on Qualitative Vision seeks to bring
together researchers from different disciplines for the active
discussion of the technical issues and problems related to the
development of qualitative vision techniques to support robust
intelligent systems. The Workshop will examine aspects of the
methodology, the description of qualitative vision techniques, the
application of qualitative techniques to visual domains and the role
of qualitative vision in the building of robust intelligent systems.
Topics to be discussed include:
o What is Qualitative Vision? (e.g., definitions, properties,
biological/psychophysical models or bases)
o Qualitative Visual Features and their Extraction (e.g., 2D/3D
shape, depth, motion)
o High level Qualitative Vision (e.g., qualitative 2D/3D models,
properties, representations)
o Qualitative Vision and Intelligent Behavior (e.g., navigation,
active or directed perception, hand-eye coordination, automated
model building)
Since the number of participants is limited to under 50, invitations
for participation will be based on the review of extended technical
abstracts by several members of the Qualitative Vision research
community. The extended abstract should address one of the above
topic areas, be 3 to 5 pages in length (including figures and
references), and it should begin with the title and author name(s) and
address(es). Extended abstracts (6 copies) should be sent, by
*April 15, 1990*, to:
William Lim
Grumman Corporation
Corporate Research Center
MS A01-26
Bethpage, NY 11714
Decisions on acceptance of abstracts will be made by May 15, 1990.

DO NOT post your vote or Followup this article (followups are directed to
news.groups). Send it to me by replying to this article or via e-mail to
the address below. If possible, include "comp.robotics YES" or
"comp.robotics NO" in the Subject: line as appropriate (put it in the
message body too). The polls are now open and will remain so through the

A little electioneering, while I'm at it:
The response to the call for discussion has been 100% favorable. However,
I'd like to see this group created cleanly and unambiguously. Please be
sure that _all_ persons interested at your site send their "YES" votes to
me for tallying. ("NO" voters are on their own. (-: [Yes, of course I'll
