Abstract

This paper discusses the development of a video localization system to be used as an automatic cameraman in interactive video discussions to eliminate the need for camera operators.The system consists of microphones, multiplexing circuit, computer and PT camera. The localization algorithm is based on comparing the amplitude level of the signals from all microphones and then selects the one with higher amplitude, strong noise presence is one of the limitations of this techniques, however the type of noise added can be clearly identified and removed in the frequency spectrum,and based on the results obtained the PT camera can be localized to cover the desired area. Initial results shows clearly demonstrate that this techniques is usable for video surveillance. The system is been developed for closed room localization but it can also be extended to outdoor applications by using suitable sensors and suitable cameras, in video discussions the system can be used in conferences and in parliament halls where such a system can be used as an automatic cameraman.
