Abstract

Our research deals with the development of a binocular system which is able to react to a stimulus and to track it.In this paper we present results which concentrate on a monocular tracking system. The imposed constraints are as follows: it must be a simple system, react quickly and be based on the biological model of vision. The developed model consists in three modules: the optical mechanism to acquire the visual information, the process module which processes the information and allows the location of the moving object, and the command module of the eye which is necessary to place the fovea on this object. The results obtained from the analyses of scenes with a unique moving object enable us to validate the chosen command. Then, we applied the system to several moving stimuli varying in sizes and velocity vectors. One of the advantages of or process module is the possibility of selecting one stimulus out of n to track it. The developed system enables us to obtain a good precision, the object is always localized by the fovea, even after a change of direction.
