I would suggest a low-powered Pentium type processor with the MMX
instruction set. The image processing surround operations showed be operated
in parallel. These primarily are unsigned 8 multiplies. Make sure you can
test for overflow. Rank operators involve a sort of 8 or more pixel values.
I do not know if any of the Ada compiler manufacturers have implemented MMX?
However, as matter of honor and advertising, they should do everything to
make sure that an Ada team has the very best chance to win. There is an Ada
pattern recognition package, which I have. It was written in Ada 83 by Byron
Harris of the Software Engineering Department of LORAL (Ford) Aeronutronic,
Newport CA 92658. I believe that Loral is no longer in Newport. This program
was supported by STARS.

FINAL REPORT - CDRL A001C REUSABLE IMAGE PROCESSING PACKAGES  CONTRACT
NUMBER N00014-87-C-2432  APRIL 28, 1988
"8  LESSONS LEARNED:   One of the major lessons learned in this project is
that Ada is a very suitable language for image processing applications. Many
of the functions produced had been programmed in other languages.  It was
not difficult to program them in Ada.  Many of the algorithms are very
computationally intense and this led to slow execution times on the VAX and
the IBM AT.  However, any high order language would have this problem."

If you wish a copy, I will supply what I have as is in ZIP format.

If at all possible, your camera should be able to rapidly sample a small
central field. This accelerates autofocusing. I highly recommend G. A.
Baxes, "Digital Image Processing" Wiley 1994 ISBN 0-471-00949-0. Another
good book is John C. Russ, "The Image Processing Handbook, 3rd ed. CRC
Press, Inc. 1998, ISBN: 0849325323. Russ has two commercial software
packages that run as plug-ins to Adobe PhotoShop. It might pay to analyze
your images with a commercial package prior to creating your software.

One option you might explore is using a translator.  I know there exists a
translator from Ada to C (I think Tucker Taft would know about where you
might be able to purchase this), and also JGNAT translates from Ada to Java
byte code if you had a chip that could run that.

Best of luck!

Hello Team Members,

I am a cadet at West Point leading the EE and CS cadets who are part of
an interdisciplinary group from our school.  This group is competing in the
9th Intelligent Ground Vehicle Competition,
http://www.secs.oakland.edu/SECS_prof_orgs/PROF_AUVSI/index.html.
Unlike the other schools, who use C++, we are going to use Ada because of
Ada's great support for real-time systems and also, it is our favorite
language.

I have a few questions for Team-Ada to help us get started.

1: We were looking into using the LART http://www.lart.tudelft.nl/
as our computer in our vehicle because of it's low power usage, low weight,
and the coolness factor in putting it together.  Will GNAT work on the LART,
which utilizes Intel's Strongarm processor?

2: Is there a computer better suited for Ada that has a low power
consumption, low weight, and would be fun to put together
(Something Transmeta?)?

3: Have any of you worked on or know of Ada resources for an
unmanned intelligent ground vehicle, frame recognition from
a video camera, or laser modeling.  Just looking for those hard
to find Ada links or references on these topics.

4: Any other suggestions or help?

Thank You,
Cadet Marcus Brakewood
