Alexander Bekiarski, Snejana Pleshkova · International Conference on Signal Processing · 2010
The popular cases of processing in audio and video robot systems are audio visual speaking person tracking and sound localization. The MPEG-4 standard described and codes video information in form of the objects, which can be the speaking persons observed with mobile robot video camera.
