Subject: Two Research Posts - Computer Vision
University of Edinburgh
Department of Artificial Intelligence
Two Research Posts - Computer Vision
Applications are invited for two researchers to work in the
Department of Artificial Intelligence on an European Institute of
Technology funded research project entitled ``Surface-Based Ob-
ject Recognition for Industrial Automation''. Principal investi-
gators on the project are Dr. Robert Fisher and Dr. John Hallam.
The project investigates the use of laser-stripe based range data
to identify and locate parts as they pass down a conveyor belt.
The vision research to be undertaken includes topics in: surface
patch extraction from range data, surface patch clustering,
geometric object modeling, model matching, geometric reasoning.
The project builds on substantial existing research.
The first researcher will be expected to take a leading role in
the day-to-day project management of this and a related project
(5 research staff total) as well as undertake scientific
research. Applicants for this post should have a PhD (or compar-
able experience) in an appropriate area, such as computer vision,
artificial intelligence, computer science or mathematics.
The second researcher will be more involved in software implemen-
tation and testing, but will be expected to undertake some origi-
nal research. Applicants should have at least a BSc in an ap-
propriate area.
Both applicants should have experience with the C programming
language. Applicants with experience in computer vision, the
UNIX operating system, the C++ language, or the Prolog language
would be preferred.
Both posts are funded for a period of three years starting No-
vember 1, 1989. The salaries will be in the range 10458-16665
(AR1a) for the first post and 9816-12879 (AR1b/a) for the second
post, with placement according to age, experience and qualifica-
tions.
Applications should include a curriculum vitae (3 copies) and the
names and addresses of two referees, and should be sent to the
Personnel Department, University of Edinburgh, 63 South Bridge,
Edinburgh, EH1 1LS by September 6, 1989, from whom further par-
ticulars can be obtained. In your application letter, please
quote reference number 1651, and indicate for which of the two
posts you are applying.

Subject: least squares fitting.
i interested in obtaining some pointers to C code which will do a least
squares fit on 2D and 3D shapes consisting of a number of discrete points.
also, are there any good reference sources to 2d or 3D shape analysis.
im particularly interested in mirror imaging and shape difference quantification

Subject: Friend looking for a image processing job in a stable company
Organization: Hewlett-Packard, Santa Clara Div.
For all you folks doing work in computer vision in the industry,
I have a question! ...Why is this group so quiet ? There are never any
[ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Good question.
phil...]
issues discussed here. Does every body work for the military ? ...
Let me make a start. I have a freind looking for a job in the image processing
area with a solid background to image processing hardware design and excellent
understanding of image processing algorithms. He has about six years
experience in the industry. Can any one recommend a stable :-) imaging,
image processing company.

Subject: Grayscale Morphology software
About 3 weeks ago, I posted a query about any existing public domain
morphology software. Firstly, I would like to thank all the people who
replied to my query, by giving me advices or answers.
Secondly, it appears that there is no public domain software for morphology
around. I was principally interested in grayscale operations.
Most of the replies I got were about general purpose software packages,
in which a few morphological operations are implemented.
I will try to give a brief compilation of the answers I got :
At the University of Washington, Linda Shapiro and her colleagues use a
a software package called GIPSY, that has about 400 commands, including
morphology, and that runs under UNIX. This is a general purpose package
that runs slowly but covers a lot of ground. The morphology is just one
command that can do dilations, erosions, openings and closings with the
user defining his own structuring element by means of entering a mask.
Finally, it costs something like $5000.
A few people at the University of Maryland working with Rosenfeld refered
me to a few existing software packages. There is one written by Serra's
team. It's called MORPHOLOG, or its new version which is called VISILOG;
the latter one is on sale by a French company (NOESIS) for about $8000.
If you want more information on MORPHOLOG, you may want to contact La"y
at the School of Mines in Paris. The software works on an hexagonal grid,
and a description of it can be found in :
B. La"y, Descriptors of the programs of the Software Package Morpholog,
Ecole des Mines, Paris.
They also refered me to an Image Processing Software package called IPS,
that has been created by a French lab in Grenoble, and they have quite a
few both binary and grayscale morphological operations running on it.
It's been developed on Appolo workstations, and is on sale for about
40000 French Francs, which is about $6000.
Apparently the same software has been implemented to work on a PC, and
is commercialized by the society Thomson-Titn, and is called SAMBA.
If you want more information on IPS, you may want to contact Guy Bourrel
at bourrel@imag.imag.fr who is implied in the development of this software.
His address is

France tel 76-51-48-13
Another general purpose image processing software package which includes
some of the basic morphology stuff is called HIPS, and is commercialized
by Mike Landy at Sharpimage Software in New York.
Finally, a word of comment to tell the netters why we are looking for
grayscale morphology tools. We have implemented some binary morphology
in our Image Processing lab (now called CIPIC (Center for Image Processing
and Integrated Computing), which is a campus-wide research unit).
It runs on an image processing board IP8500, mounted on a VAX. It does
all kind of opening/closing dilation/erosion, and can be used for
skeletonization, etc....
The next step is to implement gray scale morphology. I am working with
Professor Ralph Algazi (algazi@iris.ucdavis.edu), and we wanted to know
what the state-of-the-art is in this area.....
Thanks for listening,
Eric.
