Subject: Software for stereo vision
Organization: National Optics Institute
I would be interested in having some information about public-domain
or commercial software packages available to solve a classical stereo
vision problem for 3D reconstruction of an object. In particular our
vision system involves a stereo microscope with 60X magnification. For
the camera calibration we have to take this aspect into account.
Another particularity is that the focal depth is very narrow.
Therefore, we have to do the reconstruction with partially blurred
images.
If someone has similar experience with this type of problem, I would
appreciate some discussion with him. Thank you in advance for your
replies.

Subject: Detection of zero-crossings of LG in Kim-Aggarwal stereo algorithm.
Keywords: stereo kim-aggarwal zero-crossings
Organization: Department of Computer Science, U of Copenhagen
In their artictle "Positioning Three-dimensional Objects using stereo
images", Yeon C. Kim and J. K. Aggarwal describe a method for
relaxation labeling of feature-points. They use the zero-crossing
pattern of the Laplace-Gaussian operator to determine the initial
probability of a match.
We are currently trying to implement their algorithm and have the
following problem:
Kim-Aggarwal detect zero-crossing in a way, so that only the following 16
patterns can arise:
100 000 000 101
011 111 011 010
000 000 100 000
001 001 001 001
110 010 010 010
000 100 010 001
010 010 010 100
010 010 010 010
100 010 001 100
100 100 000 000
010 010 110 010
010 001 001 101
Where the 1's indicate a zero-crossing, and 0's indicate no zero-crossing.
Does anybody know a way of detecting zero-crossings that fulfill this
requirement, or (even better) what algorithm they used in the original
paper.
Oh, by the way, the article appeared in:
IEEE journal of robotics and automation, Vol. Ra-3, No-4, August 1987.
Thanks in advance.

From: Ken Laws <LAWS@ai.sri.com>
Subject: Computists International
*** PLEASE POST ***
This is to announce Computists International, a new
"networking" association for computer and information scientists.
Hi! I'm Ken Laws If this announcement interests you, contact
me at internet address laws@ai.sri.com. If you can't get through,
my mail address is: Dr. Kenneth I. Laws; 4064 Sutherland Drive,
Palo Alto, CA 94303; daytime phone (415) 493-7390.
I'm back from two years at the National Science Foundation.
I used to run AIList, and I miss it. Now I'm creating a broader
service for anyone interested in information (or knowledge),
software, databases, algorithms, or doing neat new things with
computers. It's a career-oriented association for mutual
mentoring about grant and funding sources, information channels,
text and software publishing, tenure, career moves, institutions,
consulting, business practices, home offices, software packages,
taxes, entrepreneurial concerns, and the sociology of work. We
can talk about algorithms, too, with a focus on applications.
Toward that end, I'm going to edit and publish a weekly+
newsletter, The Computists' Communique. The Communique will be
tightly edited, with carefully condensed news and commentary.
Content will depend on your contributions, but I will filter,
summarize, and generally act like an advice columnist. (Ann
Landers?) I'll also suggest lines of discussion, collect
"common knowledge" about academia and industry, and help track
people and projects. As a bonus, I'll give members whatever
behind-the-scenes career help I can.
Alas, this won't be free. The charter membership fee for
Computists will depend in part on how many people respond to this
notice. The Communique itself will be free to all members, FOB
Palo Alto; internet delivery incurs no additional charge. To
encourage participation, there's a full money-back guarantee
(excluding postage). Send me a reply to find out more.
-- Ken
Computists International and The Computists' Communique are
service marks of Kenneth I. Laws. Membership in professional
organizations may be a tax-deductible business expense.
