Subject: Neural networks for morphological operators
Dear all,
I am interested in having neural networks learn morphological operators
like DILATION, EROSION, CLOSING, OPENING, SKELETONIZING.
Initial attempt is an input-layer/output-layer feedforward network and
backprop learning rule.
I would appreciate any pointers to people who might have done research
in this area or to papers that might have been published since I
couldn't find *any*.
Thanks in advance,

Subject: range image archive
The range image archive has been re-established here at Washington State
University. The machine name and IP address are:
gecko.eecs.wsu.edu (134.121.32.17)
The data files live in the /pub directory tree.
Please remember to use binary mode when transferring files, and
perform ftp transfers AFTER `normal' business hours (i.e. do it
between 1700 and 0500 Pacific time). I reserve the right to disable
ftp activity during the day if it significantly impacts my ability
to use gecko for my work.
The archive has been expanded to include CAD models (IGES and polyhedral
approximations) of twenty objects. See pub/cad-models/README for details.
Also, several new images have been provided by Timothy Newman at Michigan State
University. They appear in the pub/range-images/moremisc directory. The
rest of the archive has not changed, so if you retrieved the files while
they were at Notre Dame, you don't need to get the `synth', `isolated', or
`cluttered' imagery again.
***** previous readme
This directory contains a bunch of range images produced by
- the MSU Pattern Recognition and Image Processing Lab's Technical
Arts 100X scanner (aka `White scanner'), OR
- scan-conversion software that I adapted from a program
originally written by Paul Besl many years ago.
You are free to use these images to test your algorithms. If the
images are to appear in a published article, please acknowledge the MSU
PRIP Lab as the source of the images (you don't have to mention my
name, though).
File format: rather than deal with all the goofy standards out there
for images (and to preserve the floating-point representation), these
images are compressed ASCII text files. Beware: they expand by about
10x when uncompressed. I recommend that you keep them compressed to
save disk space. Many of you will probably convert these files to
your own `local' image format anyway.
Each image file has a three-line header giving the number of rows and
columns. This is followed by four images. The first is the so-called
'flag' image, where a pixel value of 1 means the corresponding (x,y,z)
values at that pixel are valid. If the flag value is zero, you should
ignore the (x,y,z) components for that pixel.
Following the flag image is the image of X-coordinates, the image of
Y-coordinates, and the image of Z-coordinates. All are floating-point
images. MSU's White scanner is configured so that each stripe of
range values occupies one column in the image. The object is swept
under the stripe with an XY table to get an image. So the X
coordinate image is a linear ramp; the X value is taken from the
absolute position of the X stage in the XY table. The Y value depends
on the column number of the pixel, and the Z value is the measured
range (the height above a table).
You can use the 3D coordinates of each range pixel, or you can
throw away the X and Y images, and concern yourself with the Z-value
alone. Note that the `aspect ratio' of the image doesn't
have to be 1, although I try to keep it in the neighborhood of 1.
Remember to use binary mode when you transfer the images.

Subject: Colour, Texture, Fractals
Hi Netters !
I'm a research (Ph.D.) student working on the combination of
colour and texture through fractal geometry in computer vision
and this is my first mail to you all.
I'm trying to complete a good (survey,review,report) covering
all aspects of colour , texture , and the interaction of colour
with the other informations such as,texture, stereo, motion,
contour, etc...
If anyone has anything out there,
please do me a favour and send me whatsoever relevant.
Papers,comments,etc...would be much appreciated !
I will give the net all list of references when I get them.
Many thanks in advance.

Subject: Colour Image Enhancement by Colour Manipulation
Keywords: Colour Enhancement
I am presently working on my masters thesis in which I am working
on techniques to improve the appearance of colour images by changing
subtly the colours. In this way I hope to obtain an apparent contrast
improvement thus rendering detail in the image more visible.
Very little work has been in this area and so I am appealing to anyone
who may know of references relating to this. I am aware of the work
by Land and McCann (Retinex Theory) and also of the colour constancy
work done by Ron Gershon, Gershon Buchsbaum and Olivier Faugeras.
I am not really intersted in colour constancy so if anyone knows of
something relevant I'd be very grateful.
You may reply to (stuart@techunix.technion.ac.il)
Thanks
Stuart

Subject: Biomch-L
Dear Vision-List readers,
At the request of the moderator, it is my pleasure to post a summary
statement on Biomch-L@nic.SURFnet.NL / Biomch-L@hearn.bitnet at
Nijmegen University, The Netherlands.
Biomch-L is concerned with Biomechanics and (biological) Movement Science; as
such, the list has rather much overlap with the Vision List, in particular as
regards its current focus on 3-D kinematics and inverse dynamics. Recent pos-
tings and discussions -- some of which quite lengthy -- have been concerned
with:
3-D analytical photogrammetry and camera (self)calibration
3-D rigid-body movement from single and multiple camera views
on landmarks where the correspondence problem has been
solved separately or is simultaneously considered <*>
3-D definitions of instantaneous centres and axes of rotation
3-D `helical' angle definitions avoiding the singularities and
otherwise strongly correlated properties of Euler/Cardan angles
3-D definitions of net joint moments (torques/couples)
Optimal smoothing and differentiation of low-pass signal/wide-band
noisy data using natural, quintic and heptic splines with GCV
(Generalized Cross Validation)
<*> e.g., a recently announced thesis from the University of Umeaa in
Sweden.
plus discussions on their calculus. Summary descriptions of some FORTRAN
codes implementing the above are available from LISTSERV@HEARN.BITNET via
the command INDEX BIOMCH-L; individual files (some of which are for sub-
scribers only) can then be obtained by similar commands

**** CALL FOR PAPERS ****
AIS'92
3rd Annual Conference on
ARTIFICIAL INTELLIGENCE, SIMULATION & PLANNING
in
High Autonomy Systems
sponsored by
Schools of Computing Science and Electrical & Computer Engineering
Curtin University of Technology
Conference theme:
INTEGRATING PERCEPTION, PLANNING AND ACTION
8 - 10 July, 1992, Perth, Western Australia
The design and development of autonomous systems requires expertise from a
multitude of areas. The theme of this conference is the integration of
perception, planning and action using a task-directed approach. Years of
research in fields of vision and perception, planning, knowledge
representation, modelling, reasoning, control, simulation and many others,
have culminated in the development of models that are useful in limited and
separate domains. However, integration of these modules in automated
intelligent systems has proved too computationally expensive. In all these
fields there is a shift towards situated reasoning and task directed problem
solving. Action requires intelligent decision making, and the choice of
action is based on results of close interaction between task directed sensory
perception and situated reasoning. The underlying issue is the
representation and modelling of the relevant aspects of the environment, and
problems encountered here are closely related to those in intelligent
simulation. Techniques in computer simulation can provide useful models that
serve as the foundation for simulating the behaviour of autonomous agents,
and such simulation can provide meaningful insight into the agent's
behaviour. This conference seeks to provide an opportunity for researchers
from a range of disciplines and application domain projects to interact and
address these issues.
SUGGESTED TOPICS:
The topics covered in this conference will include (but will not be limited to)
the conceptual as well as application-oriented issues in the following areas:
* Active vision systems with task-oriented or purposive problem-solving
* Temporal, spatial, and situated reasoning in automated planning
* Integration of qualitative and quantitative reasoning
* Process planning and control
* Reasoning with uncertainty
* Rule-based modelling and simulation
* Intelligent integrated systems
* Learning in highly autonomous systems
* Adaptive and neural based control
* Fuzzy logic control systems
* Distributed and parallel intelligent simulation
