Subject: Camera Calibration?
Hello,
I am trying to implement a stereo algorithm (by Aloimonos) and will
need to calibrate our camera.
Is there a public domain calibration code available?
If not, what is the fastest to implement that gives decent results?
We don't need fantastic accuracy.
Any help would be greatly appreciated.
Thanks,
Jon

I'm looking for software routines to compute optical flow fields from
image sequences. Spatiotemporal energy model preferred. Any major
programming language and image format OK.
Thanks in advance for any leads.

Subject: Frame grabber with adjustable gain
I have two boards from the Imaging technology inc. They call it the
PCvision Plus Framegrabber. It is IBMpc compatible and I am using it
on a 386 for analysis and inspection of surface texture.
It has a programmable offset voltage and gain facility. I have not yet
tried this since I am still not completely involved in this project.
As per the specifications it allows the user to program the control
registers to add a gain from .67 to 1.33 in 100 steps.

Subject: 2D images?
Hi,
I ftp'd to the vision list archive imagery database and looked at the README
file and got some message that the database is being set up again. My
question is this. Does that mean that it just isn't accessible and if so,
could you tell me approximately when it will be accessible? Also, I'm
looking for a dataset with the following description. Does any of this
potentially accessible data fit this description?
Thanks,
--Charlie
Here's the description of what I'm looking for. If you don't have it here,
could you please post this to comp.ai.vision?
I'm looking for a database of 2-D images to test some synthetic discriminant
functions on. Here are my basic requirements:
Resolution -- roughly 128x128.
Views -- I would like to have a couple of similar images (for discrimination
purposes) with 360 degrees of rotation in increments of no greater than 5
degrees. Something like 1 or 2 degrees would be much better. The rotations
could be in-plane or out-of-plane, but the increment should be small.
Gray-scale or binary images are fine and I don't really care what the actual
images are. I prefer something like IR or SAR data, but intensity will do.
Ideally, I'd like to be able to place these images in some natural
background to test the identification ability of the filters. This sounds
like I need military targets, but it isn't necessary. If someone could
point me to, say, a set of characters or tools with all rotated views, that
would be fine.
The databases I have access to now either have too large an increment in
rotation view or don't have a large enough distortion range to test over.
By the way, I've considered using some interpolation routine to create my
own data set, but it tends to distort the images more than I want.
So in summary, what I would like is a set of clean, isolated training images
with some constant lookdown angle, but an aspect that varies in small
increments.
Regards,
--Charlie

Subject: wanted: wireframe system program
Hi,
does anyone know have a (C or C++) program to set up a datastructure for objects
and to draw a wireframe projection (with hidden line removal) of these objects
in a 2D pixel image?

Subject: Re: IBM RS600 digitizer
Hi Folks,
I am looking for a framegrabber to capture motion video on an IBM RS6000.
I need a board that can capture at least 4 to 5 frames a second (if
not more). B&W or Color input is fine. Any information regarding this
will be highly appreciated.

Do you have any public domain vision software or any contacts for commercial
source code vendors? I am compiling a list of sources for vision source/object
code as well as a source database of algorithms of the "freely distributable"
type and I would be very grateful for any information you can give me.
I am also compiling a short booklet on useful vision contacts, groups, sources
of software/hardware, products, systems, commercial companies, etc dealing with
machine vision which I intend to publish in the "Ruff Guide to Machine Vision"
(nominal cost). If any anyone is interested in contributing information to the
guide I am eager to receive any contributions that may be of general interest
(eg info on products etc or useful algorithms, methods, reviews of
products and equipment giving good and bad points, etc). Any info submitted
must be free of copyright.

Subject: Vision/graphics faculty position at Stanford
Please forward the following job announcement to anyone who might be
interested in applying.
==========================================================================
STANFORD UNIVERSITY
Department of Computer Science
The Computer Science Department of Stanford University is seeking
candidates for a tenure-track assistant professorship in the areas of
computer vision/computer graphics. Specific areas of interest
include, but are not restricted to, physically-based modeling and
animation, model generation, active vision, sensor fusion, invariants
for vision, illumination models, and geometric foundations for
vision/graphics. The successful candidate will be a computer scientist
who is proficient in developing the underlying algorithmic techniques,
and in building prototype systems to demonstrate the algorithms in
specific applications. Candidates must have demonstrated outstanding
research and teaching abilities.
Stanford University is an affirmative action/equal-opportunity
employer. Women and minorities are especially encouraged to apply.
Applications, including a curriculum vitae and names of five references,
should be sent to Professor Leonidas J. Guibas, Robotics Laboratory,
Computer Science Department, Stanford University, Stanford, CA 94305.

Subject: Post-doctoral Visiting fellow in Biomedical Image Processing
[I am sending this message for a friend. Please reply to the address
reported below. Thanks, S.G.]
We have one open position, to be filled in as soon as possible, for an
NIH VISITING FELLOW.
The successful candidate will participate in our research program in
biomedical image processing. He will be part of the BEIP/image processing
group which comprises experts in image processing, pattern recognition and
mathematics. The candidate will be responsible for designing and
implementing new algorithms for the quantitative analysis of multimodality
images of the brain. This particular research project is a collaborative
effort with neuro-scientists from the National Institutes of Mental Health.
Typical problems that will need to be addressed are :
- image registration (intra-subject, inter-subject as well as
inter-modality);
- noise reduction in PET images;
- automatic detection of anatomical structures;
- processing of image sequences;
- multivariate statistical analysis.
This research offers some challenging problems in image processing and a
unique opportunity to get familiarized with state of the art techniques in
diagnostic and functional imaging. The ultimate goal is to develop a
system that can be used by other scientists at NIH to study brain function
and to detect functional abnormalities in psychiatric diseases such as
depression. In short, we would like to find someone with a good practical
sense, an interest for advanced research and development, and a strong
desire to see his research output used by others for a noble cause.
In consequence, we are looking for a person having the following profile:
- a Ph.D. degree in Electrical Engineering or Computer Science (less
than 5 years);
- an expert knowledge of image processing and analysis;
- a strong knowledge and appreciation of software engineering (C, Unix,
and eventually C++);
- a desire to work in a multi-disciplinary environment;
The initial appointment is for 1 year; it can be easily extended for at
least 2 other years depending on the results obtained.
Letters of application including a resume, some sample papers, and
references should be sent to:
Dr. Michael Unser
BEIP/NCRR, Bldg 13, Room 3W13
National Institutes of Health
Bethesda, MD 20814, USA
A preference will be given to those candidates that can start as soon as
possible (meaning right away).
PLEASE: if absolutely necessary, short questions can be sent by e-mail to
unser@helix.nih.gov, but we would prefer receiving applications and resume
by POSTAL mail.
