The introduction of video sensors into a sensor network allows existing sensor network applications to be enhanced as well as providing for new applications which cannot be supported by typical scalar sensor networks. This is due to the vast amount of information which can be obtained from an image. Scalar data is insufficient for many applications such as video surveillance and traffic monitoring. Whereas, camera sensors collect video data, which are rich in information and offer tremendous potential when used in wireless sensor networks. Video sensor networks continue to gain increase interest due to their ability to collect video information for a wide range of applications in recent years.
