In recent years most of the applications of WSNs are supported with array of image/video sensors to enhance the performance. Multiple co-existing cameras deployed can provide different views of the same area or target which enhances the view of scene of interest. The redundancy introduced by multiple, possibly heterogeneous, overlapped sensors can provide enhanced understanding and monitoring of the environment. But individual transmission of these images of same scene of interest from multiple co-existing cameras unnecessarily consumes energy and degraded image quality.
