We also have a 386 with one of the PCvision Plus Framegrabber boards
in it. However, we also have a series 150 image analysis system, also
made by Imaging Technology Incorporated. If you're interested in this
company's products, I highly recommend that you try to go the more
expensive route and get the series 150. Ours is equipped with an
analog-digital converter, one frame buffer board, and an arithmetic
logic unit board. The difference in flexibility between the two
systems is considerable--in particular, if you want to write text or
objects on top of an image, you can do so non-destructively with the
series 150. To the best of my ability to tell, that's not possible
with the PCVision Plus (ask me about dynamic overlays if you're
interested).
More germaine to the topic at hand, however, is that the series 150 is
noticeably more sensitive. This device also has both gain and offset
control for the incoming analog signal, but settings range from 0-255
instead of 0-100. If you have a problem with getting enough light to
your camera, you want the series 150. With that setup I can see
images where I see nothing but black level noise in the PCVision
system.
Although the series 150 is a seperate unit, we're using it in
conjunction with another 386 clone.

Subject: looking for 2-D pattern matching software.
I'm looking for commercial software that will do pattern matching or
recognition. the scanned image has to be compared against a library of images
and then a best fit has to be selected. i'm interested in companies that
develop this software and more specifically in commercially available software
packages and on which system they run (crays excluded :->). as i don't read
this newsgroup frequently, direct e-mail would be prefered.
thanks in advance,

AAAI-93 Workshop on
Reasoning About Function
========================
Washington D.C., July '93
Description of Workshop:
The explicit representation and use of the function (purpose) of an object,
either as intended by its designer or as interpreted by its user, is
emerging as a focal point of problem solving in fields as diverse as
Device Invention, Redesign, Diagnosis, Explanation Generation and
Automatic Debugging. Explicit treatment of function has proven to be
very useful because of its potential to organize and provide access to
causal knowledge of the object (eg., focuses on missing causality
during redesign), because of the improved resolution it brings
to the reasoning process (eg., discriminates among suspects
during diagnosis) and because of its utility in addressing the scaling
problem. To date, function-based knowledge has been successfully
applied in several domains, including Software Engineering, Human
Physiology, and various fields of engineering such as Electrical,
Aerospace and Chemical Engineering.
The objectives of this workshop are: 1) to examine current techniques
used to represent and reason about function; 2) to present a forum to
develop a shared framework for reasoning about function, and 3) to
identify the trends and future directions for this emerging field.
Topics
The workshop will focus on the following issues:
1) Terminology: theoretical analyses yielding an appropriate
vocabulary for function; disambiguating function from other terms such
as behavior and teleology: what are the interactions and dependencies
between them? How do form, use, experience, etc. relate to function?
2) Representation: What are the issues in acquisition of function
knowledge? What are the ontological bases of an adequate function
representation: processes, states, flows, parameters? How can
representational primitives be chosen in a given ontology? What impact
does the intended use of a function model have on its construction?
How is knowledge of function related to behavioral, structural and
heuristic knowledge?
3) Reasoning: What are the sorts of tasks/domains for which Functional
Reasoning is particularly well suited? What are the AI processes
involved in exploiting function knowledge during reasoning? How can
reasoning about function, behavior, teleology, etc. be integrated into
a coherent system?
4) Applications: An examination of implemented systems, i.e.,
representation and reasoning techniques used, evaluation of the system
and lessons learned from the experience.
Format of Workshop:
The workshop will address the work of participants in the form of
moderated presentations and discussions. Where appropriate,
participants will be invited to display posters describing their work.
Separate sessions will be devoted to terminology, representation
issues, reasoning and application issues. The workshop will conclude
with a summarizing panel discussion.
Attendance:
Participation is by invitation only, and will be limited to
approximately 35 people. See Submission Requirements below for the
criteria to be invited.
Submission Requirements:
Those who wish to attend the workshop should submit four copies of a
1-2 page research summary including a list of relevant publications,
regular and email address (where possible) and phone and FAX number.
Those who wish to present their work at the workshop should submit
four copies of a short paper (6-8 pages) in addition to the research
summary. If the work has been published or submitted for consideration
elsewhere, please specify the journal or conference. Note that,
unpublished work is preferred for presentation. Electronic submissions
will not be accepted. All submissions will be reviewed by the Workshop
Committee.
In order to facilitate interaction among participants, you are
requested to specify the following with regard to your work: topic
(terminology/representation/reasoning/application), field
(redesign/diagnosis/explanation generation etc.) and domain
(electrical/chemical/physiology etc.). In submitted papers, you are

\begin{Abstract}
For a Lambertian surface, it is possible to recover a dense
representation of shape in the form of surface normals at each
visible point by using a single color image of the surface. The
positions, strengths, and spectral content of illuminants need
not be known a priori [1]. This capability is contingent upon
the surface being illuminated by a set of lights that vary
spectrally with orientation from the surface, and is a
generalization of the photometric stereo method. This "shape
from color" method is thus restricted to one particular
reflectance model, and works for a single surface at a time only.
The Lambertian model means that the surface normal is related in
a linear way to the RGB color observed for each pixel; the
linearity holds only if the lights are linearly independent both
in space and in color space. Surface normals are recovered up to
an overall orthogonal transformation. Linearity means that the
Gaussian sphere is transformed into an ellipsoid in color space,
and one can easily solve for the ellipsoid using least squares.
Once one introduces another reflectance model, however, the
linearity and hence the solvability of the model breaks down.
Nevertheless, if the linearity-breaking mechanism is the
addition of specularities to a base Lambertian reflectance it may
still be possible to recover shape if many pixels produce
reflected light according to the Lambertian model. In that case
one may treat specular highlights as outliers on top of a
basically ellipsoidal shell in RGB space. Several robust models
exist for discounting such outliers. Here we use a least median
of squares method. Once one has identified the Lambertian
ellipsoid, outliers, now identified as specular highlights, may
be omitted from an analysis of shape. Thus one both recovers
shape and detects specularities at the same time.

Abstract
The use of Reduced Instruction Set Computers for scientific applications is
common today. Advances in processor design and compiler technology make it
possible to perform large-scale computations on RISC workstations. The RISC
design provides simple instructions that operate at high speed and compiler
optimisations employ the machine's capabilities to perform naively programmed
operations with reasonable efficiency. However, there remain opportunities for
improvement in execution performance by optimising the design of the high-
level language program, and, conversely, there are also traps for the unwary
programmer. Partial unrolling of loops and employing scalar variables to assist
the compiler in the use of registers are two simple techniques that can yield
performance improvements of up to 50% depending upon the compiler and the
architecture. Unexpected performance penalties as high as 500% may be paid for
cache conflicts, where two large data arrays are contending for the same cache
locations. This report discusses how to improve the performance of critical
code sections in scientific programs, and how to detect and avoid cache
conflict performance penalties.
