| Abstract: |
The problem of automatic detection and recording of active speaker talks among more than thirty participants located in the medium meeting room is not solved completely. In the developed smart meeting room techniques of video tracking and audio source localization are implemented for recording AVI files of speaker messages. Video processing of streams from five cameras serves for registration participants in fixed chair positions, tracking main speaker and recording view to the audience. The experiments showed that the developed audiovisual system captured messages of all the speakers. The detection error of beginning and ending of speech message had acceptable rate. |
