Subject: Information request for object recognition papers.
I would appreciate pointers and references to current work in object
recognition. My group is beginning work in the automation of visual
database design for real-time image generators. These databases consist
of polygonal approximations of real-world objects (everything from houses
to bushes). Currently, individual objects are constructed by hand, using
models, maps, photographs, graph paper, geometry, and lots of time and
patience. We would like to develop a modeling station which can extract
the basic geometry of objects from sets of photographs, and which can
produce good approximations to polygonal models of the regular structures,
such as buildings and other cultural features, which it recognizes in the
source photographs.
We expect that such a system will require some operator assistance for
resolving ambiguities, at least initially, but even such a system would be
of great help in the modeling task.
Although we have some papers of current work, please assume that we are
completely ignorant about who is doing what, and what the state of the
art is, and forward all references to me. I realize that there are probably
several netlists which are relevant, but I've not kept in touch with these.
Pointers to the more active and relevant of these are also appreciated.
I will summarize the responses if they are sufficiently general for this
audience, and if the volume of replies warrants it. Many thanks in advance.

[The best collections of papers are the DARPA Image Understanding
Workshops. The February '87 proceedings have been made available
to the general public. Much of this work is oriented toward aerial
cartography (as well as target recognition). Other good papers
have appeared in recent vision conferences such as PRIP/CVPR/ICCV
and in journals such as IEEE PAMI and CVGIP.
Some of the most pertinent work is being carried out at SRI by
Pascal Fua and Andy Hanson. They have developed ways of extracting
rectilinear objects (i.e., buildings of complex shape) and are
extending their techniques to identify roads and vegetation.
One of the inputs to their system is a segmentation map derived
from my own work in computer vision. -- KIL]

The Proceedings of the conference are copyrighted by John J. Grefenstette
the editor. At the time of the conference (and perhaps now) he was at
Vanderbilt University. You could contact him about procuring the book, or
contact John Holland, the conference chairman, at the University of Michigan.
Your university library should be able to assist with procurement of these
proceedings and any doctoral dissertations you might need. They probably
have extensive inter-library loan resources.
Again, good luck!

The "International Conference on Genetic Algorithms & their Applications"
was held July 24-26, 1985, at Carnegie-Mellon University. It was jointly
sponsored by Texas Instruments & the US Navy Center for Applied Research
in Artificial Intelligence (NCARAI). The editor was Professor John Grefenstette
at Vanderbilt University.
I took a course on Genetic algorithms from Professor Grefenstette last year.
However, I believe that he has moved to another school by now. Vanderbilt
should be able to point you to him, and he has copies of the proceedings.

I strongly agree. Any safety-critical system should have certain
characteristics: it should be rigorously specified (AT LEAST the safety
aspects); it should be possible to reason rigorously about the
implementation, to convince others that it matches the specification;
it should be developed using QC/QA techniques that guarantee an audit trail
so that any faults discovered after development can be traced to their
cause.
These considerations dictate the use of mathematically rigorous methods, and
a certified Quality Assurance regime. Does anyone know of an AI system
which measures up? Please reply by mail - I'll summarise.

Automatic checking and automatic grading are different things. I think
<<* 3. WEAK: I think *>>^
automatic computer checking is a good thing, especially for spelling
and simpler grammar.
But there is no reason to grade automatically, just let the students
^<<* 23. SENTENCE BEGINS WITH BUT *>>
work on their papers (with the automatic checker) until they are satisfied.
<<* 21. PASSIVE VOICE: are satisfied. *>>^
<<* 17. LONG SENTENCE: 24 WORDS *>>^
Then have them turn in their work and the final computer critique to a human
grader.
The situation is similar to programming, where the compiler
automatically checks the syntax. It would be unthinkable to make people turn
in programs without letting them compile the programs first. On
the other hand it would unthinkable to leave a syntax error in
when the compiler tells you right were it is.
<<** SUMMARY **>>
READABILITY INDEX: 10.42
Readers need a 10th grade level of education to understand.
STRENGTH INDEX: 0.41
The writing can be made more direct by using:
- the active voice
- shorter sentences
DESCRIPTIVE INDEX: 0.65
The use of adjectives and adverbs is within the normal range.
JARGON INDEX: 0.00
SENTENCE STRUCTURE RECOMMENDATIONS:
1. Most sentences contain multiple clauses.
Try to use more simple sentences.
<< UNCOMMON WORD LIST >>
The following words are not widely understood.
Will any of these words confuse the intended audience?
CRITIQUE 1 SYNTAX 2 UNTHINKABLE 2
