Subject: Intensity Calibration
Does anyone have any literature or experience on calibrating color or
monochrome cameras in applications where machine vision is used for
measurement. I am particularly interested in the calibration
procedure and not the use of machine vision for measurement. I will
summarize any replies.

Subject: help with camera specs
Our team has been asked to recommend a camera (or cameras) for either
a mono or stereo vision system (they haven't decided which they want
yet). Being a more software oriented team, we don't have musch
experience establishing specifications to approach vendors with. If
anyone can give us some advice, or point us to any journal articles
that would help, we would greatly appreciate it. Please respond by
e-mail and if we get some interesting replies, we'll summarize.
Thanx in advance,

Subject: Range imagery added to the Vision List Archive
The subdirectory RANGES-IMAGERY has been added to the Vision List Archive.
This data will be later reestablished at a public ftp archive at WSU.
This directory contains a bunch of range images produced by
- the MSU Pattern Recognition and Image Processing Lab's Technical
Arts 100X scanner (aka `White scanner'), OR
- scan-conversion software that I adapted from a program
originally written by Paul Besl many years ago.
You are free to use these images to test your algorithms. If the
images are to appear in a published article, please acknowledge the MSU
PRIP Lab as the source of the images (you don't have to mention my
name, though).
File format: rather than deal with all the goofy standards out
there for images (and to preserve the floating-point representation),
these images are compressed ASCII text files. Beware: they expand by
about 10x when uncompressed. I recommend that you keep them
compressed to save disk space. Many of you will probably convert
these files to your own `local' image format anyway.
Each image file has a three-line header giving the number of rows and
columns. This is followed by four images. The first is the
so-called 'flag' image, where a pixel value of 1 means the corresponding
(x,y,z) values at that pixel are valid. If the flag value is zero, you
should ignore the (x,y,z) components for that pixel.
Following the flag image is the image of X-coordinates, the image of
Y-coordinates, and the image of Z-coordinates. All are floating-point
images. MSU's White scanner is configured so that each stripe of
range values occupies one column in the image. The object is swept
under the stripe with an XY table to get an image. So the X
coordinate image is a linear ramp; the X value is taken from the
absolute position of the X stage in the XY table. The Y value depends
on the column number of the pixel, and the Z value is the measured
range (the height above a table).
You can use the 3D coordinates of each range pixel, or you can
throw away the X and Y images, and concern yourself with the Z-value
alone. Note that the `aspect ratio' of the image doesn't
have to be 1, although I try to keep it in the neighborhood of 1.
Remember to use binary mode when you transfer the images.

From: LEBOWITZ@VAX1.Mankato.MSUS.EDU
Subject: Image processing network system
Several colleagues and I are working on a proposal to a Unix-based
system intended exclusively for image-processing applications on
campus. We have the ability to add hardware to our existing campus
network so that researchers could access shared software from their
offices and labs.
I'm interested in recommendations for a suitable hardware/software system
that could be shared by folks in astronomy, biology and physics. Presumably
we would acquire a workstation rather than a full mainframe since the
number of users wouldn't be that extensive. We'd like to have the
ability to use Macintosh and IBM Windows interfaces from our individual
offices to display images, but rely on a common operating system (preferably
Unix) for our programming needs.
I'll try to summarize your responses if you mail them directly to me at this
address:

Subject: Postdoc position
The following job description cam across my desk which may interest
someone with vision experience.
DIGITAL IMAGE ANALYSIS/MACHINE VISION OF PLANT GENETIC
RESOURCES (seeds, seedlings, and pollen)
POSTDOCTORAL RESEARCH ASSOCIATE POSITION, USDA/ARS
National Seed Storage Laboratory, Fort Collins, CO
POSITION: Agricultural Engineer/Agronomist/Plant
Physiologist/Computer Imaging Specialist
DESCRIPTION OF DUTIES: The incumbent will conduct research to
develop methods to measure growth rates of germinating seeds and
pollen using computer digital image analysis techniques. The
incumbent will work with other research scientists and staff at
NSSL. The overall goal is to detect early deterioration of seed and
pollen germplasm, provide physiological and imaging standards for
measuring seed germination and develop a reference digital image
database of normal and abnormal seeds, seedlings, and germinated
pollen. The information, techniques and databases will provide a
foundation for the understanding and use of digital image analysis
in the domains of plant germplasm preservation, evaluation, and
utilization.
SPECIAL REQUIREMENTS: Knowledge of digital image analysis
(machine vision), plant and seed physiology. Skill and/or experience
in computer programming, graphics programming in "C" and numeric
analysis.

CALL FOR PAPERS
10th European Conference on Artificial Intelligence (ECAI 92)
August 3-7, 1992, Vienna, Austria
The European Conference on Artificial Intelligence (ECAI) is the
European forum for scientific exchange and presentation of AI research.
The aim of the conference is to cover all aspects of AI research and to
bring together basic research and applied research. The Technical
Programme will include paper presentations, invited talks, panels,
workshops, and tutorials. The conference is designed to cover all
subfields of AI, including non-symbolic methods.
ECAIs are held in alternate years and are organized by the European
Coordinating Committee for Artificial Intelligence (ECCAI). The 10th
ECAI in 1992 will be hosted by the Austrian Society for Artificial
Intelligence (OGAI). The conference will take place at the Vienna
University of Economics and Business Administration.

SUBMISSION OF PAPERS
Authors are requested to submit to the Programme Chairperson 5 copies of
papers written in English in hardcopy format (electronic and fax
submissions will not be accepted). Submitted papers must be unpublished,
original work and substantially different from papers currently under
review. They must not be submitted elsewhere before notification date.
This restriction does not apply to workshops and similar specialized
presentations with a limited audience.
Papers can be either long papers (completed research: maximum 5000 words
/ 10 single-spaced pages) or short papers (ongoing research: maximum
2000 words / 4 pages). Each full page of figures counts as 500 words.
Each paper should contain an abstract (maximum 200 words). A separate
title page should include the title, the name(s) of the author(s),
complete address(es), the specification of one of the above topics, and
the category long or short. Papers should be printed on A4 or 8.5"x11"
sized paper in letter quality print, with 12 point type (10 chars/inch
on typewriter).
Work described in an accepted paper may also be illustrated with a
videotape or a demo. Special sessions will be scheduled for video
presentations and demos. Authors wishing to show a videotape or a demo
should specify the duration and the requirements of the videotape/demo
when submitting their paper for review.
TIMETABLE
Papers must be received by the Programme Chairperson before January 17,
1992. Authors will be notified of acceptance or rejection by April 1,
1992. Final camera-ready papers must be received by May 15, 1992.
WORKSHOPS
Workshops are welcome at ECAI 92. They will give participants the
opportunity to discuss specific technical topics in a small, informal
environment, which encourages interaction and exchange of ideas.
Workshop proposals should be sent to the Programme Chairperson as soon
as possible, but not later than January 17, 1992. Workshop proposals
should contain a brief description of the workshop and the technical
issues addressed, a preliminary schedule, and the names and addresses
(postal, phone, fax, e-mail) of the Organizing Committee of the
workshop. The proposals will be reviewed and the organizers will be
notified not later than February 28, 1992. The organizers are
responsible for producing a call for participation, for reviewing
requests to participate and for scheduling the workshop activities
within the constraints set by the conference organizers. Workshops will
be scheduled outside the main technical programme.
