| Abstract: | In this research work we deal with the problem of automatic speaker tracking by camera. Such tracking systems do exist nowadays, but they suffer from a number of problems such as: the response time due to the system inertia, the disturbing motor noise and the mechanical oscillations of the mechatronic module. In order to overcome these problems, we thought to employ a virtual tracking system using a fixed camera that does not require any mechanical part. We have proposed and conceived a virtual tracking system which is able to ensure the required task by using only two cardioid microphones and a classic video camera. Hence, in this research work, we will present two main tasks: the first one deals with the problem of audio speaker localization with only two microphones and the second one deals with the problem of virtual camera orientation. However, in our virtual tracking system, the task of speaker tracking is ensured by the orientation of the ROI (Region Of Interest) of the camera towards the active speaker. Experiments of virtual speaker tracking by camera have been done off-line, in a small meeting room without echo cancelation. Results show the good performances of the proposed localization methods and a correct tracking by the new virtual technique. [ABSTRACT FROM AUTHOR] |
