Dear TC10 members and friends,

Welcome to TC10 news #50. The primary announcements in this
newsletter are the updates on the GREC'97 workshop and the Graphics
Recognition Contest and the program for the IEEE Document Image
Analysis Workshop.

The contest web site
now has sample images and the source code for generating synthetic
images in a controlled manner. Please let me know if there are any
problems downloading the images and code or in compiling the code.

If you intend to participate in the contest, please let me know as
soon as possible. We need to have a good idea of how many people are
taking part in the contest in order to work out the logistics. Even if
you are not definite at this point, but think that there may be a
chance that you may participate, please let me know.

Second Call for Participation

Graphics Recognition Contest

to be held in conjunction with

the 2nd IAPR Workshop on Graphics Recognition (GREC'97)
Nancy, France, August 22-23, 1997

This is the second announcement of the Graphics Recognition Contest to
be held in conjunction with the 2nd IAPR Workshop on Graphics
Recognition (GREC'97), Nancy, France, August 22-23, 1997. The contest
will test the participants' ability to segment text from graphics and
to recognize graphical primitives such as lines, arcs, and
circles. The specifications and the evaluation protocol for the
contest will be intentionally kept simple in order to encourage

Detail on the contest including sample synthetic images, ground truth
files, and source code for generating the synthetic images can be
found at the web site


I encourage you to click on the "View Tar Archive" link for synthetic
images and to further click on the "README" file in the
archive. Please read this file to get in-depth information on

o how the synthetic images were created
o what is the format of the ground truth files
o how you can vary the parameters to make the text segmentation and
graphics recognition easier or harder

Dr. Ihsin Phillips is working on the evaluation protocol and
software. These should be available soon through the contest web site.

Prospective participants should visit the web site frequently
to get updates on source code, images, evaluation, etc.

I have a small set of real AutoCAD files and TIFF G4 images that I
have made available on the web site. These images were provided
courtesy of Professor Bob Haralick. I am looking for more real CAD
files and TIFF images for use in the contest. I would appreciate any
contributions of CAD and image files.


All prospective participants must contact the contest chair as soon as
possible. In addition to stating the intent to participate, they must
provide the following information:

1. Which hardware platform (e.g., Sun SPARC, Intel Pentium, ...) would you
like to run your software on at the live contest?

2. Which operating system (e.g., Sun Solaris 2.5, Windows 95, NT4.0,
3.1, ...) would you like to run your software on at the live contest?

3. Any other special needs for the contest.

> Subject: Four half-day tutorials offered at CVPR '97.

Four half-day tutorials will be offered before the
coming CVPR'97 in Puerto Rico in June 1997. The tutorials
cover a wide range of topics, from current issues in image
retrieval to new approaches to sensor design.
A brief description of the tutorials is included below.
You can register by using the general CVPR registration
form at http://marathon.csee.usf.edu/cvpr97.html.

Sunday June 15 Morning


Prof. David Forsyth and Prof. Jitendra Malik, U.C. Berkeley

Very large collections of pictures are now common, and there is a
desperate need to be able to index them. Since users generally
want to find images depicting particular objects, the application
focuses attention on important research problems in computer
vision. Partial solutions to these problems lead to useful systems,
because often the only alternative is to index the
collection by hand.

Sunday June 15 Afternoon


Prof. Peter Meer, Rutgers University

Robust estimation techniques have become standard
tools in computer vision. The tutorial discusses robust techniques
in the context of image understanding problems, and provides
practical suggestions for achieving the best possible results.

Monday June 16 Morning


Dr. Vladimir Brajovic and Prof. Takeo Kanade, Carnegie Mellon University

Computational Sensors are chips which tightly integrate
sensing and processing. Successful sensors have been
demonstrated for computer vision applications and are
typical of the next generation of vision sensors.
The tutorial will review several representative examples of
computational sensors and will cover basic (primarily analog)
techniques for computation in VLSI.

Monday June 16 Afternoon


Dr. Les Novak, Lincoln Laboratory, Massachussets Institute of Technology

This tutorial presents a basic understanding of synthetic
aperture radar imagery. Basic SAR image characteristics
will be defined and demonstrated using real and simulated
SAR. Basic techniques for SAR processing, filtering, and
object recognition will be described. Advanced SAR processing
techniques, such as superresolution, will also be addressed.

> Subject: Special Issue on Defect Detaction: Journal of Real-Time Imaging (AP)

Academic Press

Quality control is a crucial issue for any production process, and many of
the traditional methods for defect detection in manufacturing are rapidly
changing. Real-time defect detection of shape, colours and textures is
becoming mandatory for many products (from tiles to cars, from food to
airplane components) made of a variety of materials (fabric, marble,
leather, plastic and so on) to meet increasingly demanding quality
standards. For this reason, several researchers have been studying parallel
architectures, special chips and algorithms for real-time defect detection.
Thanks to such new technologies, many new applications have already become
possible, and others, unfeasible until today because of the limitations of
inspection methods, are being developed and implemented.

AIM: The aim of this special issue is to inform practitioners as well as
researchers timely of innovative defect detection techniques and their
possible applications.

SCOPE: The special issue is focussed on real-time techniques and
architectures, both software and hardware, for
- recognition and classification of defects;
- detection of defects in texture and pattern;
- detection of shape defects;
- detection of defects in colour;
- defect modeling: fractals, statistic, etc.;
- automatic acquisition of models suitable for defect detection;
- validation techniques for defect detectors.
