Subject: Help: Computational Sensors for Vision
Hello,
I am searching for any information regarding VLSI sensors for
computer/robot vision with processing capabilities. I am very
interested in references of:
-Computational sensors
-CMOS/BiCMOS image sensors with processing capabilities
-Integrated focal plane processors
-3D Sensors / rangefinders
-Other specialized imagers (motion, log-polar mapping, sub-
pixel interpolation, etc.)
-Specialized cameras with processing capabilities (edge extrac-
tion, motion computation, image transformation).
Please reply to my e-mail address, I'll post a summary.
Thanks in advance.

I need to find some 3D Skull (brain) images generated from CT or MR slices.
Would anyone be kind enough to either supply me either with a ftp site
or post them to me. Use of these images will be ackknowledged. Any common
image format or postscript will be fine.

3 D V I E W N I X
3DVIEWNIX is a transportable, very inexpensive software system
developed by the Medical Image Processing Group, Department of Radiology,
University of Pennsylvania, Philadelphia. It has state-of-the-art
capabilities for visualizing, manipulating, and analyzing multidimensional,
multimodality image information. It is designed to run on UNIX machines
with X-windows. It uses a data protocol that is a multidimensional
generalization of the ACR-NEMA standards. We have tested it fairly well
on SGI and Sun worksatations. It also runs on IBM RS6000, HP 700 series
and even PCs. We charge $1000.00 for the software which comes with source
code and manuals. You can modify and do whatever else you want as long as
it is for your own noncommercial use. For further information contact :

Subject: Help: Spectral Characteristics of remotely sensed images.
Could any one guide me to references that deals with the analysis
of IR images. I need to know how the spectral characteristic of
the various landforms changes due to atmospheric/environmental
changes (ie. temperature, moisture, humidity etc.).

Subject: $495 Mono frame grabber: Any good?
Hi Everyone,
Is the ImageNation monochrome frame grabber any good or is it
a "you-get-what-you-pay-for" kind of thing? Its 512 x 484 at 8
bits resolution and includes a C library. I don't need brilliant
software, but I want to know if the hardware is sound. This is
personal money, so I would appreciate *any* responses.
