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.
