Subject: fish-eye transformation
Hi,
I need some info, and I don't know where to get it.
Maybe you can help me?
I'm a grad student at the AI-Lab of the Free University of Brussels,
and I use a camera mounted on the ceiling (perpendicular to the floor) to track the path of an autonomous robot moving around in a room. To have a view as
large as possible, I use a fish-eye lens on the camera.
I heard somewhere that it is possible (ie. there are formulas) to transform
the distorted image back into a cartesian coordinate-system. So, what I need
are the formulas to undo the spherical aberations. These are formulas that
take (u,v) coordinates, and transform them into (x,y) coordinates in the
cartesian plane.
Do you know what I need to know? Or where I might get what I need to know?
Thanks for replying, if you can.
Bye,
George.

Subject: OCR on NIST Database fl3
Keywords: OCR, Zernike transform
I am working on an OCR-problem for handprinted digits, using a RCE-similar
neural network developed at our University and features derived from the
Zernike moments. The algorithms have been tested on several sets of digits,
including the "fl3" NIST-dataset (a subset of NIST Special Database 1),
available via anonymous ftp from magi.ncsl.nist.gov.
Since I would like to compare my own and some other people's results on the
same data, I am looking for reports/papers about OCR experiments with this
database/dataset. Please send me a message if you have been using the
"fl3"-set in your work or if you know of anybody who has.
Please send all messages per e-mail, since we sometimes have problems with
our news-server.
Thanks,

UNDERSTANDING IMAGES
Artists, designers, scientists, engineers and educators share the
problem of moving information from one mind to another. Traditionally,
they have used pictures, words, demonstrations, music and dance to
communicate imagery. However, expressing complex notions such as God
and infinity or a seemingly well defined concept such as a flower can
present challenges which far exceed their technical skills. The
explosive use of computers as visualization and expression tools has
compounded this problem. In hypermedia, multimedia and virtual
reality systems vast amounts of information confront the observer or
participant. Wading through a multitude of simultaneous images and
sounds in possibly unfamiliar representations, a confounded user asks:
What does it all mean?
Since image construction, transmission, reception, decipherment and
ultimate understanding are complex tasks strongly influenced by
physiology, education and culture; and since electronic media
radically amplify each processing step, then we, as electronic
communicators, must determine the fundamental paradigms for composing
imagery for understanding.
Therefore, the purpose of this conference is to bring together a
breadth of disciplines, including, but not limited to, the physical,
biological and computational sciences, technology, art, psychology,
philosophy, and education, in order to define and discuss the issues
essential to image understanding within the computer graphics context.

SAC '94
SAC is the annual conference of the ACM Special Interest
Group on Applied Computing (SIGAPP). For the past eight
years, SACs have been a primary forum for applied computing
practitioners and researchers. Once again, SAC'94 will be
held in conjunction with the 1994 ACM Computer Science
Conference in Phoenix. This year, SAC'94 will bring together
SIGBIT, SIGFORTH and SIGSMALL/PC, each one of which will
have their own track within SAC'94.
Although papers and proposals, tutorials and workshops which
deal with the conference themes, namely, STRATEGIC TECHNOL-
OGY TRANSFER and INTELLIGENT BUSINESS APPLICATIONS, are
especially encouraged, papers which deal with all areas of
applied computing are solicited. Of particular interests in
AI, Biomolecular Computing, Cognitive Science, Computational
Biology-Chemistry-Physics and Geosciences, Reliability,
Electronic Libraries, Multi-Media, Geographical Information
Systems, Image Processing, Logic and Symbolic Programming,
Office Automation, Software Reliability and Intelligent Sys-
tems. Proposals for special sessions and panels are also
encouraged.

Abstract
Dynamic world modeling requires the integration of multiple sensor
observations obtained from multiple vehicle locations at different
times. A crucial problem in this interpretation task is the presence
of uncertainty in the origins of measurements (data association or
correspondence uncertainty) as well as in the values of measurements
(noise uncertainty). Almost all previous work in robotics has not
distinguished between these two very different forms of uncertainty.
In this paper we propose to model the uncertainty due to noise, e.g.
the error in an object's position, by conventional covariance
matrices. To represent the data association uncertainty, an
hypothesis tree is constructed, the branches at any node representing
different possible assignments of measurements to features. A
rigorous Bayesian data association framework is then introduced that
allows the probability of each hypothesis to be calculated. These
probabilities can be used to guide an intelligent pruning strategy.
The multiple hypothesis tree allows decisions concerning the
assignment of measurements to be postponed. Instead, many different
hypotheses are considered. Expected observations are predicted for
each hypothesis and these are compared with actual measurements.
Hypotheses that have their predictions supported by measurements
increase in probability compared with hypotheses whose predictions are
unsupported. By ``looking ahead'' two or three time steps and
examining the probabilities at the leaves of the tree, very accurate
assignment decisions can be made.
For dynamic world modeling, the approach results in multiple world
models at a given time step, each one representing a possible
interpretation of all past and current measurements and each having an
associated probability. In addition, each geometric feature has an
associated covariance that models the uncertaity due to noise.
This framework is independent of the sensing modality,
being applicable to most temporal data association problems. It is
therefore appropriate for the broad class of vision, acoustic and
range sensors currently used on existing mobile robots.
Preliminary results using ultrasonic range data demonstrate the
feasibility of the approach.

Subject: List of References Re: Integration of Multiple 3d Views (long)
Some time ago I requested info on the above subject.
I was literally overwhelmed by the response! Here's a list of the
references that were given to me by kind souls on the net.
I've taken some liberty in editing the formats for the sake of
consistency, and haven't sorted them in any way (sorry).
Thanks to all those who responded.
Have fun!

Subject: Non-rigid motion form Image sequences.
Status: RO
Hello,
I am planning to do a review of all the techniques used in estimating
non-rigid motion from image sequences for a class project. I would appreciate
it if you can send me any information and references dealing with the topic. I
plan to cover both 2-D and 3-D image sequences. You can send me e-mail at
bsabata@zeus.ee.utexas.edu
I will compile all the information I recieve and post it here so that anyone
can use it.
thanks
Bikash
