Subject: Looking for Colour cameras for a stereo robot head
Recently Jean Hsu requested info on colour cameras. I have been
using colour cameras since 1989 for a robotic based vision project.
The cameras are elmo's EM102PAL with a C-mount adapter to a Cosmicar
lens. This has proved to be an amazing camera with a very high spec:
1/2" interline transfer 579(H) x 583(V)
weight 25 grams
size 54.5 long, diameter 17.5 mm
I am using two of these cameras in a stereo vision robotic sensor
device with controllable focus, aperture, and independent vergence.
Synchronisation is no problem; the cameras are sync'd together and
then feed two Datacube digimax boards, ensuring that left and right
images are frozen in the framestore at the same time.
We have recently had some interest in our stereo head and
are manufacturing them for other research groups at cost price. For
a six degree of freedom system the cost is typically 19,000 pounds.
For further details or more information (publications, full spec's,
etc) you can contact me above by email or by post to
the address below.

Subject: CCD with hexagonal grid?
Colleague in electrical engineering is looking for a CCD chip that
samples on an hexagonal grid rather than rectangular (his description follows).
Any information from vision-list subscribers would be appreciated.

HEX CHIP
it is desired to obtain a CCD chip/camera that samples on exact
hexagonal locations. it is acknowledged that carver mead and the group
at cal tech have developed a simulated retina, this is not our desire.
instead, we have developed filtering algorithms that would seem to be
optimal on hexagonal sampling. but it is desired to demonstrate by
comparing a hexagonnaly sampled image with a rectangularly sampled
image, where each have been sampled at the same density. an array of
512x512 is desired burt any will be considered.

Subject: Colour Constancy Code
I am currently researching computer colour vision and I am in need of
code, preferably in C, for colour constancy. Any algorithms for
achieving colour constancy will also be appropriate. Your help will
be very much appreiciated.
Thankyou.

\begin{Abstract}
We present a method for recovering the shape of a single Lambertian
surface, with unknown but uniform reflectance, from a single RGB image of the
object. The method depends upon the linearity of the relationship between RGB
sensor responses and surface normal directions that stems from the Lambertian
model. The algorithm follows closely upon work on the photometric stereo
method. However, that method requires as input three separate black and white
intensity images, each taken separately, whereas the method set out here needs
only one color image. For the method to succeed, the lighting color must vary
with direction from the surface. We test the method by including three
separate point light sources all contributing to the illumination of the scene.
The method correctly recovers surface normals, up to an overall orthogonal
transformation.

Subject: Multiresolution motion estimation (summary)
Hello,
some weeks ago I posted a query about multiresolution motion estimation.
What follows is the essential part of the messages I have received so far.
I am grateful to all the people who helped me with these references
and other suggestions.

the Journal of Biomechanical Engineering, and a variety of Biomedical

- look at the Pearlman, Abdel-malek paper on hierarchal PEL
recursive (Netravali related). I believe it was last months SPIE.
(From: <bloomer@alydar.crd.ge.com>)
- Mathematical Morphology and other nonlinear smoothing operations have
proven to be useful and interesting. Our reaction-diffusion shape
representation framework, yielded what we call the ``Entropy Scale-Space''
which contains gaussian smoothing as a special case. This was presented
at the International Conference on Visual Form, Capri, Italy, May 1991.

- Peter J. Burt has a brief paper on benefits of multiresolution representation
for many problems, including motion estimation. I think it was published
in IJC on PAttern Recognition in 1988, or 1990, it is worth looking up.
(From: <totic@suna0.cs.uiuc.edu>)
- A lot of my work is involved with stereo processing to reveal depth
information. I believe there is alot of overlap between stereo and motion.
Our stereo work uses a scale space approach. We perform stereo matching
at a course level (where the images have been heavily blurred, generally
by a Gaussian filter), the output of which 'guides' matching at finer levels
of resolution.

the "classic" article on 1-D scale-space by Witkin.

============================ WORKSHOPS =================================
Workshops are part of the ECAI92 scientific programme. They will give
participants the opportunity to discuss specific technical topics in a
small, informal environment, which encourages interaction and exchange
of ideas. Persons interested in attending a workshop should contact the
workshop organizer (addresses below), and the conference office (ADV)
for ECAI92 registration. Note that all workshops require an early
application for participation.
A full description of all workshops can be obtained by sending an email
to ecai92.ws@ai.univie.ac.at, which will automatically respond.
