LLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLL JAMES L. CROWLEY holds the post of Professor at the Institut National Polytechnique de Grenoble (INPG), France. He teaches courses in Artificial Intelligence, Machine Vision, Robotics and Signal Processing at l'Ecole National Superieure d'Informatique et de Mathematiques Appliques (ENSIMAG). He is coordinator of the European Computer Vision Network (ECVnet), an EC "Network of Excellence" as well as the DG-XII Human Capital and Mobility network SMART whose subject is the development of techniques for a mobile autonomous surveillance robot. Professor Crowley served as the technical coordinator of project ESPRIT basic research project EP 7108, "Vision as Process" from 1989 to 1995. The VAP Project developed active vision heads, model architectures for real time continuously operating computer vision systems, and a theory of control of perception. In the area of mobile robotics, Professor Crowley has developed systems for world modeling and navigation using computer vision and ultrasonic range sensors. Versions of these systems are used commercially by Denning Mobile Robotics, and Helpmate Robotics. Professor Crowley has published two books, two special issues of journals, and over 100 articles on vision and mobile robotics.
