Subject: Help on 2D vision software/hardware
help wanted:
working on automating tissue culture procedures, specifically cutting
and transportation of small pieces of plant tissue. It is intended
that a small robot arm (mitsubishi) be directed by a simple vision
system to the centroid of the plantlet.
Assistance is required with the vision system:
suggestions for a suitable software/hardware configuration
for a PC based environment.
Comments on experience with the Mitsubishi RV1-MING robot would also
be appreciated.
thanx.

From: matt@thrush.umesve.maine.edu (Matt McGranaghan)
Subject: Pointers to simultaneous contrast models?
I am looking for pointers to literature on modeling simultaneous color
contrast effects. The application is this: In choropleth maps, each
enumeration district (states on a map of the U.S.) is colored to signify
some data value for each district. But the appearance of each district
is modified by the colors of the states around it, potentially making
map reading quite difficult. I want to predict the amount and direction
of modification of each color, and then "correct" for the contrast
effects by building a display in which the predicted apparent colors
signify the data values, rather than the "naive" colors. My initial
attempts have dealt with achromatic maps but I hope to work with color.
The modeling style of several retinex researchers seems relevant:
choropleth maps are much like the set of colored areas in the mondrian
images often used in retinex work. Indeed, simultaneous color contrast
seems to be the annoying flip side of a color constancy mechanism.
If you are aware of any efforts to model (i.e. predict) simultaneous
contrast effects, please point me to them. Thanks.

Subject: Two questions: half-tone to Postscript, and, VICOM-VME
I have 2 questions:
1) Does anyone have or know of anyone who has a public domain
half-toning program that will give 100dpi PostScript output?
2) Has anyone out there had any experience using a
VICOM-VME image processing system? If so, did you have as terrible an
experience with it as we have?
Thanks,
Keith Bartels

University of Toronto
Research Associate in Vision/Robotics
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 March 15, 1991 to:
Professor John K. Tsotsos
Department of Computer Science
University of Toronto
Toronto, Ontario, Canada M5S 1A4
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.

Morphological shape and region description
by C. Ronse and B. Macq
Philips Research Laboratory Belgium
Abstract.
A new algorithm for multiscale description of binary digital regions is
given. A region is represented by a growing sequence of subsets
approximating it; each approximation is obtained from the previous one
by addition of the opening by a structuring element chosen in a finite
family. The structuring elements vary in size and shape, and are chosen
at each step according to two criteria: largest structuring element size
and greatest increment in the size of the approximation. The algorithm
satisfies meaningful algebraic properties and converges to a final
result in a bounded number of steps. It allows also an economical
representation of shape in terms of structuring elements, and so it can
be applied in binary image coding.
If you want a (printed) copy, please send me your SNAIL MAIL (not
e-mail) address, including ZIP CODE and COUNTRY (unless Belgium), and
the TITLE of the preprint.

CALL FOR PAPERS
Progress In Neural Networks
Special Volume on Neural Networks In Vision
Significant progress has been made recently in the application of neural
networks to computational vision. To showcase this research, Ablex Publishing
is planning a special volume on "Neural Networks in Vision", scheduled for
1992. This volume will be a part of "Progress in Neural Networks", an annual
book series reviewing research in modelling, analysis, design and application
of neural networks.
Authors are invited to submit original manuscripts detailing recent progress
in neural networks for vision. The paper should be tutorial in nature, self
contained and preferably, but not necessarily, about fifty double spaced pages
in length. An abstract and an outline are due by January 31, 1991, the full
paper by Feburary 28, 1991. Make submissions to
