Subject: vision book list: addendum
I received a few more suggestions of important books on vision since I
sent my summary to the list. Here they are:
M.A. Fischler & O. Firschein: "Readings in Computer Vision: Issues,
Problems, Principles, and Paradigms", Morgan Kaufmann, Los Altos, CA,
1987.
A.P. Pentland: "From Pixels to Predicates", Ablex Publ. Corp., Norwood,
NJ, (1986).
Blake & Zisserman: "Visual Reconstruction"
Besl: "Range image Understanding"
Someone also suggested a special issue from a serial journal:
"Artificial Intelligence", special isue on Computer Vision, Vol. 17
(1981).

Vision Wizards:
I need to find a 2 degree of freedom camera mount (rotation and pitch).
The mobile platform I work on is only about a foot tall, and the top is
cluttered with various hardware etc. Thus to give the robot a view of
its world, we need to set the camera up on a pole. Once its up their it
needs to be able to turn around and either look down at what the arm is
doing, or out at where the base is going. Point is, I don't have the
slightest idea where to look for such a device. If anyone could give me
a starting point as to where to get such a mount, especially one easily
controlled through a PC parallel or serial port, I would be most
greatful.
Thanks in advance,
Ethan Evans

[ Please post responses to the List

We are in the process of developing a small two axis camera mount as
part of a third generation video-rate sign-correlation stereo and motion
system that we are building this summer at Teleos Research.
The camera mount has the following approximate specs:
Pan range: infinite (or till your camera wires break)
Pitch range: -90 to 90 degrees
Accuracy: 11 min of arc
Height: 21 cm
Diameter: 9.7 cm
Weight: 0.68 kg
Controller boards (for the IBM PC, VME, STD, and Multibus) are available for
operating the pan-pitch head in absolute position mode, incremental position
mode, or velocity mode. We plan to use this device to hold a stereo camera
fixture that also provides vergence control for binocular stereo work.
We have not thought about making this device commercially available but that
is a possibility. If interested contact Jeff Kerr or myself at Teleos
Research.

Hi,
I'm trying to establish contact with researchers in the visualization
field who work in Israel.
If you are, or you know somebody who is, I'd appreciate you sending me
a message (please send me a presonal message, even if you are also
posting it on this list).
Thanks,

Subject: IJPRAI CALL FOR PAPERS
IJPRAI CALL FOR PAPERS IJPRAI
We are organizing a special issue of IJPRAI (Intl. Journal of
Pattern Recognition and Artificial Intelligence) dedicated to the
subject of neural networks in vision and pattern recognition.
Papers will be refereed. The plan calls for the issue to be
published in the fall of 1991. I would like to invite your
participation.
DEADLINE FOR SUBMISSION: 10th of December, 1990
VOLUME TITLE: Neural Networks in Vision and Pattern Recognition
VOLUME GUEST EDITORS: Prof. Josef Skrzypek and Prof. Walter Karplus
Department of Computer Science, 3532 BH
UCLA
Los Angeles CA 90024-1596
Email: skrzypek@cs.ucla.edu or karplus@cs.ucla.edu
Tel: (213) 825 2381
Fax: (213) UCLA CSD
DESCRIPTION
The capabilities of neural architectures (supervised and
unsupervised learning, feature detection and analysis through
approximate pattern matching, categorization and self-organization,
adaptation, soft constraints, and signal based processing) suggest
new approaches to solving problems in vision, image processing and
pattern recognition as applied to visual stimuli. The purpose of
this special issue is to encourage further work and discussion in
this area.
The volume will include both invited and submitted peer-reviewed
articles. We are seeking submissions from researchers in relevant
fields, including, natural and artificial vision, scientific
computing, artificial intelligence, psychology, image processing
and pattern recognition. "We encourage submission of: 1) detailed
presentations of models or supporting mechanisms, 2) formal
theoretical analyses, 3) empirical and methodological studies. 4)
critical reviews of neural networks applicability to various
subfields of vision, image processing and pattern recognition.
Submitted papers may be enthusiastic or critical on the
applicability of neural networks to processing of visual
information. The IJPRAI journal would like to encourage
submissions from both , researchers engaged in analysis of
biological systems such as modeling
psychological/neurophysiological data using neural networks as well
as from members of the engineering community who are synthesizing
neural network models. The number of papers that can be included
in this special issue will be limited. Therefore, some qualified
papers may be encouraged for submission to the regular issues of
IJPRAI.
SUBMISSION PROCEDURE
Submissions should be sent to Josef Skrzypek, by 12-10-1990. The
suggested length is 20-22 double-spaced pages including figures,
references, abstract and so on. Format details, etc. will be
supplied on request.
Authors are strongly encouraged to discuss ideas for possible
submissions with the editors.
The Journal is published by the World Scientific and was
established in 1986.
Thank you for your considerations.

Hi,
I've only got two references for you - but they have 42 and 69 references,

references!).

Apparently, the state of the art in connectionism, as a lot of people
will tell you, I'm sure, is Y. Le Cun et al's work which can be found
in NIPS 90. Other significant connectionist approaches are
Fukushima's neocognitron and Denker et al's work which I *believe* is
in NIPS 88.
I am interested in handprinted character recognition. Type set
character recognition is basically solved, and I believe you shouldn't
have any trouble locating texts on this (although I've only looked at
the text edited by Kovalevsky (sp?), which I believe is just entitled
"Reading Machines". Bayesian classifiers, which you can read about in
any statistical pattern recognition text (eg, Duda and Hart, Gonzalez,
etc), are capable of performing recognition, since one can choose
reliable features present in machine printed text (eg, moments,
projections, etc), and the segmentation problem is fairly trivial).
Perhaps the greatest problem in handprinted recognition is the
segmentation problem. Unfortunately, most connectionist approaches
fail miserably in this respect, relying on traditional methods for
segmentation which become a bottleneck. I am inspecting connectionist
methods which perform segmentation and recognition concurrently, and I
recommend you do not inspect the problems independently.
I am by no means expert in any area which I've commented on, but I
hope this helps. Also, again, please send me your compiled responses.
Thank you and good luck.
