COMPUTER VISION GROUP
---------------------

The Vision group (currently 9 persons) is part of the AI and Vision research 
team, which comprises approximately 16 members. The Computing Science 
Center is composed of about 60 members: approx. 10 faculty members, 10 post-
docs, 35 research assistants/graduate students. The "Vision group" is headed 
by Prof. Thierry Pun, the "AI group" by Prof. Christian Pellegrini.



MAIN INTERESTS IN COMPUTER VISION

We pursue two series of objectives. First, on the theoretical side, we aim at a 
better understanding, modelling and usage of the knowledge concerning human 
perception. We think that this should lead to new concepts and results, of 
value for pre-attentive vision as well as for higher levels of the system.

Second, we wish to apply our work to practical problems. We have tried to 
identify a sector with practical importance, as well as theoretically 
non-trivial. This is the case with agricultural robotics, or agrotics.

Other projects are enumerated below.

Theoretical computer vision:
 - features extraction via neuronal modelling;
 - shape inference;
 - scale determination;
 - grouping;
 - spectral and intrinsic characteristics;
 - focus of attention;
 - representation of geometrical and high-level information;
 - reasoning;
 - learning.

Applied computer vision:
 - agricultural robotics (POTATO OPERATION);
 - medical image processing;
 - industrial image processing;
 - expert systems for medical information processing;
 - software tools development for image analysis.

LaboImage:

We are distributing (free) LaboImage, an image analysis software that we have 
developed during the past 3 years. It is used for teaching and research. It 
has a menu-driven interface, an extensive set of image processing/analysis 
capabilities (filterings, transforms, segmentation, binary and grey-level 
morphology, etc.), some special purpose tools (particles counting, 1D gel 
analysis, etc.). It is written in C. It currently runs under SunView; a 
Motif-X11 implementation is planned. Interested people should contact T. Pun.



EQUIPMENT

General purpose hardware of the Computing Science Center:
 - Suns: Sun 3 series, Sun 4 series;
 - MacIntosh: SE, II;
 - Silicon Graphics: IRIS PC;
 - Hewlett-Packard: 9000/835;
 - ALR 386.

The AI and Vision people mostly work on Sun hardware. There is approximately 
one workstation per researcher.

Specialized hardware:
 - Dunn Microcolor 638 HSC, image hardcopy on films;
 - video camera MINTRON MTV-1003CB, 512x512x8 + Occulus board;
 - Eikoniks 1412 camera, 4096x4096x12 + VME board (on Sun 3/160).
