Subject: 3D Tracking
Hello,
I'm a student of computer science at the Technical University of
Munich and I'm working on my disertation about tracking a roboter's
hand. I've read many articles about it, but there was no one good enough
to solve my problems. So I hope to find someone to tell me more about
it or to give usefull hints about other articles.
The experiment:
There is one roboter moving its hand in a 3-dimensional way. A SINGLE
camera is observing this movement from outside the scene. The camera is
a stationary CCD camera.
The goal:
The goal is to track the roboter's hand, based on the received
monocular image sequences. The tracking should be 3-dimensional.
The problem:
I have to calculate the exact 3D coordinates of the roboter's hand
by using the 2D images from the stationary single camera. Only the motion
could help.
The questions:
- Has anbody already worked at this problem?
- Are there usefull articles about that?
( 3D-Tracking , 2D->3D from motion )
I will thank you for any help
Bye

Subject: DataCube Server
Announcing the Free Release of the
DataCube Server
Roger Kahn
Micheal Swain
University of Chicago
The DataCube Server, developed at the University of Chicago,
distributes the MV200 and DigiColor boards across the network. This
server is designed to be a tool for studying real-time computer vision
by allowing multiple vision clients to simultaneously connect to the
DataCube and process images in parallel. The DataCube Server is easy
to use (many clients can be written without knowledge of ImageFlow),
easily extendable, fast, and fully documented.
The DataCube Server provides a network interface to a set of functions
that have been written on the MV200 and DigiColor. At the heart of
these functions is a Gaussian pyramid (6 levels) with a mobile fovea
that allows a common scale and spatial attentional mechanism. The
functions currently supported include:
- color and greyscale multiresolution frame acquisition from camera
or disk
- foveated image display
- image histogramming
- color histogram backprojection and intersection
- 24 to 8 bit image conversion
- motion detection from a moving platform
- sobel convolution.
Nearly all of these functions have been packaged into Pipeop Altering
Threads (PATs) for maximal speed, but clients can be written in C++
that use these functions without any programming knowledge for the
DataCube.
The DataCube Server can be easily be extended so that you can add your
own DataCube functions. The DataCube Server is written in C++ as a
class hierarchy of client services. The base class of this hierarchy
provides functions for making common paths (such as from an AM memory
to the crosspoint switch) as well as memory management and other
services necessary to produce context independent functions. Since
the functions are independent new routines can be added to the server
without having to know which resources other routines use. The C++
interface to ImageFlow can also be used to write non-server DataCube
functions.
-----C++ INTERFACE TO IMAGEFLOW-----
We have made the header files for ImageFlow 2.3.6 C++ compatible.
These headers have been used with ATT C++ 2.1 and 3.0, Sun C++ 3.0,
and Lucid C++ 2.2 and 3.0. The interface declares all standard
ImageFlow functions as extern "C" and provides a class for the MV200
and DigiColor that simplifies programming. The members of this class
handle system initialization, produce common paths, allocate memory,
and keep track of when LUT's and other elements need to be reset. The
member functions in this class can be called inside of PAT's for
time-critical functions. This class is fully documented.
-----C++ INTERFACE TO KHOROS-----
The DataCube server provides a C++ class for operating on images that
is based on the Khoros Visualization and Image File Format (VIFF)
(version 1.5). Since this image class is bassed on the VIFF many of
the Khoros library functions are available. Khoros provides functions
in the following categories: arithmetic, classification, color
conversion, data conversion, file format conversion, feature
extraction, frequency filtering, spatial filtering, morphology
filtering, geometric manipulation, histogram manipulation, statistics,
signal generation, linear operations, segmentation, spectral
estimation, subregion, and transforms.
-----SYSTEM REQUIREMENTS-----
- DataCube MV200 and DigiColor boards
- ImageFlow 2.3.6
- Networked Sun SparcStation running Unix
- C front 3.0 compatible C++ compiler (templates are required)
- Khoros is recommended, but not required
(available via anonymous ftp from pprg.eece.unm.edu, 129.24.24.10, in
the /pub/khoros directory, see DataCube Serve documentation for details)
-----OBTAINING THE DATACUBE SERVER-----
The DataCube Server is available via anonymous FTP from
ftp.cs.uchicago.edu (IP number 128.135.20.100) as a compressed tar
file in /pub/artificial_intelligence/kahn/DQ_Server called
DQ_Server.tar.Z. Documentation is in DQ_Server_doc.tar.Z. An
installation script is also provided in the file INSTALL. Binaries
are available by request.
-----WHY WE ARE DISTRIBUTING THE DATACUBE SERVER-----
By distributing the DataCube Server we hope in encourage the exchange
in information and code in the vision and DataCube communities.
Furthermore, we feel that the DataCube Server and the C++ interface to
ImageFlow can be used as a standard foundation for DataCube code.
Since this platform encourages context independence, code integration
is simplified.

Subject: AI CD-ROM Revision 2 - press release
We actually started shipping the Rev.2 discs a couple of months ago but due
to the number of orders already waiting to be filled we didn't want to send
out press releases until we'd caught up. Anyway, things seem to be going
along fine at this point, so here's the press release! The hard copies are
going out to the trade mags at about the same time, so they'll probably
start showing up in a month or so.
For people wanting to see a complete listing of the CD's contents, look for
the file AICDROM2.ZIP at an ftp site near you. The file is also available
from the Compuserve AI forum, and the NCC dial-up BBS at 214-258-1832. It
contains the file listing, this press release, a couple of magazine reviews
of the disc, and other assorted information. Oh, and one last note regarding
pricing - customers have told us that Programmer's Pardise seems to have the
best pricing in the US on the disc...
