Subject: examples of openings?
In mathematical morphology, one defines an opening as an operator F such
that:
1) F is idempotent: for any X, F(F(X))=F(X);
2) F is anti-extensive: for any X, F(X) is less than or equal to X;
3) F is increasing: for any X,Y, if X is less than or equal to Y, then
F(X) is less than or equal to F(Y).
A well-known example is the opening by a structuring element B, which
transforms a set X into the union of all translates of B contained in X.
Other examples exist: (a) For a fixed point p, the operator extracting
from a set X its connected component containing p. (b) The intersection
of a set with a fixed set A.
I would like to have as many as possible examples of openings of an
unusual type arising in practical problems of image analysis.

Subject: Survey on image processing based on diffusion-like computation
I am compiling a survey on image processing based on diffusion-like
computation. Meaning, all type of algorithms that can be described by
a (linear/nonlinear) heat equation. I'd appreciate any references to
this kind of work. I'll summarize the responses to the net.
Thanks in advance!

Subject: Human brain MR images
We are looking for human brain MR images for our vision research. We
have heard that Barrow Neurological Institute (Phoenix, AZ) might be
able to offer those images. Can anyone tell us how to contact them?
(It would be most helpful if the source of data specify image content,
resolution, format, etc.)
Any suggestions or pointers will receive a warm welcome ! In a few weeks,
if I get a sufficient response, I will submit a listing of this information.

Subject: Angiogram images of human coronary artery
Status: RO
I am looking for digitized angiogram (DSA) pair of the entire human
heart from a biplane x-ray system. The views should be 90 degrees
apart, so that I can match one view to the other. If you have any
pointers or can help me with this please send email to:
agr@imed.wayne.edu

RA and Post-Doc positions available
The Centre for Cognitive Science, University of Western
Ontario, London, Canada, has openings for a Research
Assistant and a Post-doctoral Fellow beginning in the summer
of 1990 or Jan 1, 1991. Areas of research include human
vision and visual attention, motion and texture perception,
and human-computer interaction. The Centre is well equipped
with a network of 10 SUN workstations, a Silicon Graphics
machine with 3-D capability, and special hardware for vision
experiments. The research and staff are supported by the
Information Technology Research Centre (a Province of
Ontario Centre of Excellence), the Institute for Robotics
and Intelligent Systems, and the Canadian Institute for
Advanced Research. Research staff have access to the
network of researchers associated with these institutes.
Candidates with experience in both experimental design and
in building computational models will be given special
consideration. Salaries commensurate with qualifications
and experience.
