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,

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

                      MS A01-26
                      Bethpage, NY 11714
Decisions on acceptance of abstracts will be made by May 15, 1990.

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
