Abstract:
The goal of this diploma thesis is to develop a face recognition system that uses CCD camera fixed on a robot arm. In order to extend the ``visual field'' of the system the robot moves with the camera. The task of the system is to find people and to identify them. After a general introduction some methods of face recognition and detection are explained. The structure of the system and its tasks are presented. To evaluate the whole system a database consisting of people from the staff of the department ist created. The goal is then to check if a person entering the room belongs to the staff or not. In case the person belongs to the staff its name should be given. \\The system consists of the following major modules: Motion detection, Face detection, and Face recognition. In particular, the following methods are used within the modules: Motion Energy detection for Motion detection, Multilayer Perceptrons for Face detection, and the Eigenface approach of Turk & Pentland for Face recognition. \\After evaluating the individual modules we tested the face recognition system on different people entering the observation room. Provided one person stays app. 10 seconds in the observation room, the overall rate is 82,4 \% which is a good result considering the speed of one frame per second on fully automatic face recognition.
