From: flynn@shillelagh.cse.nd.edu (Patrick J. Flynn)
Subject: PD Range Image Archive
Back in February, I made 44 range images available for anonymous ftp
from my workstation at Michigan State University, and said:
>> I will try to keep these images available [...]
>> until I leave MSU this summer.
>> If my next job has machines with internet access and some disk space,
>> I'll put them there.
The archive has been expanded (over 200 images, including 100 synthetic
images generated from CAD models) and moved from Michigan State to
my Sun here at Notre Dame. The machine name and IP address is:
shillelagh.cse.nd.edu (129.74.9.7)
The images are in the pub/range-images directory. The README file from
that directory appears below. Please remember to use binary mode
when transferring files, and perform ftp transfers AFTER
`normal' business hours (i.e. do it between 1700 EST and 0800 EST). I
reserve the right to disable ftp activity during the day if it
significantly impacts my ability to use shillelagh for my work.
Direct *specific* questions about the images to me (flynn@cse.nd.edu).
General questions about range sensing are best answered by reading
the surveys by Jarvis (PAMI '83), Nitzan (PAMI '88), or Besl
(in the `Advances in Machine Vision' book by J. Sanz, pub. by Springer,
or in the `Machine Vision and Applications' journal, volume 1).
A European version of the archive is in the works (courtesy of Adrian
Clark). I will post details to vision-list when we get it set up.
Here is the text of the README file in the pub/range-images directory.
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.
Contents:
In this directory, there are 4 subdirectories:
NAME SIZE CONTENTS
cluttered 1302KB 10 White Scanner images of pairs of objects
isolated 9270KB 100 White Scanner images; 5 images of each of 20 objects
misc 6008KB 47 `miscellaneous' images of various objects
The files labeled `foot1' and `foot2' are images of
a human foot (belonging to Dr. Rick Hallgren). Most
of the others are blocky, industrial-ish parts.
synth 22027KB 100 synthetic images; 5 images of each of 20 objects
(the same 20 objects as in the `isolated' directory).

From: Massimo Tistarelli <tista@dist.dist.unige.it>
Subject: RE: Optical Flow in Realtime
I have developed a system for the computation of the optical flow in
real-time using the Connection Machine. It is capable of computing a
dense optic flow from image sequences at near real time, allowing the
computation of one velocity field at a rate of 20 frames per second.
The program is Public Domain, I can send it directly to you or you can
ask Thinking Machines Co. in Cambridge (MA), together with related
documentation.
Also the time-to-impact can be computed at almost no "extra cost" in
terms of processing time. As the algorithm is devised, it will be
possible to realize an implementation of the system on other parallel
machines. I' m currently working on it!
Regards,
Massimo Tistarelli

Thanks to all those who volunteered information on public domain
image processing packages. Here is a summary.

From: Stephen M. Pizer <smp@cs.unc.edu>
I write in response to your news item requesting info on public domain
image processing packages using X.
UNC's /usr/image image processing package is Unix and X based. It is in the
public domain and is licensed and distributed by softlab@cs.unc.edu for a
copying cost of $300. It is installed in around 40 sites worldwide, most of
which are involved in medical image processing. It consists of a collection
of image access modules, numerous X-based display modules, including 2D, 3D,
and cinematic display, and a wide range of around 75 image processing,
analysis, and utility programs. Maintenance is not provided. Further
information can be obtained from gash@cs.unc.edu.

From: yangchen%iris.usc.edu@usc.edu (Yang Chen)
Well, we have an OBVIUS system from MIT available from
whitechapel.media.mit.edu. It provides some basics for doing image
processing using LISP. It runs under either SunView or X-window.

b. Use "anonymous" or "ftp" as the user name.
Name (pprg.unm.edu:login): anonymous
-or-
Name (pprg.unm.edu:login): ftp
c. Use your e-mail address as the password; please care-
fully use a valid e-mail address, as this version site
logs all anonymous ftp's.
Password (pprg.unm.edu:user): {your valid email
address}
331 Anonymous login ok, use your E-MAIL address as the
password.
230 Guest login ok, access restrictions apply.
d. Get the release notes for acquiring Khoros via
anonymous ftp (note that "RELEASE_NOTES.ftp" is the
plain text file - both ".ms" and ".ps" files are avail-
able for those who would like them).
ftp> cd /pub/khoros
ftp> get RELEASE_NOTES.ftp
2) UPS Delivery
If you would like to have a tape and printed documenta-
tion sent to you, send the order form below (last page)

UNM EECE Dept., in U.S. funds) to:
KHOROS
Room 110
Department of EECE
University of New Mexico
Albuquerque, NM 87131
We will begin shipping tapes (source, binaries and printed
documentation) no earlier than November 1st. Please
remember, this is a BETA release; the final release will be
complete in January 1991. There will be no support or
updates provided for the beta release.
KHOROS REQUIREMENTS AND LIMITATIONS
To run Khoros, you must have a UNIX platform running
the X11R3, X11R4, or OpenWindows servers. The Khoros system
consists of ~350,000 lines of C code; it requires ~100 Meg
for storage for source, documentation and binaries. To com-
pile Khoros, the system requires X11R4 from MIT (patch lev-
els 1-18), and an additional ~30 Meg of storage.
If you have questions or problems,
mail rasure@bullwinkle.unm.edu.
Once you have the system and want to report bugs or comments,
mail khoros-bugs@bullwinkle.unm.edu.
