| Abstract(in English) | This paper proposes an automatic speaker detection method with visual information for the videoconferencing. Recently, some papers reported the same aim using microphone array method. We pay attention the fact that the movement of the speaker's mouth is large compared with other participants'. Then we detect the mouth and compute its movement. After the person's face region is detected, the location of between the eyes, left and right eyes, and nose are detected. Finally, the location of the mouth is detected. The mouth tracking is applied the template matching with updating. We identify the speaker who is the large error. We took 16 simulated scenes of videoconferencing, and obtained all parts of all 42 persons. Moreover, the resulting detection rate was 100% (as the frame was 99.1%) and we confirm the validity of our method. |
