Scientists and engineers in computers, information, and electronics offer a broad reference on networks of visual sensors. They cover foundations of visual information processing in wireless sensor networks, energy efficient information processing and transmission, collaborative information processing, and hardware technology and applications. Among specific topics are energy efficiency and reliability considerations of a compressive sensing technique, the low level representation of data, object association through multiple camera collaboration for large-scale surveillance systems, using line cameras for monitoring and surveillance sensor networks, and the digital zoo.
