Distributed video sensor networks
Large-scale video networks are becoming increasingly important for a wide range of critical applications such as video surveillance, the monitoring of disaster zones and traffic, elderly care, the tracking of people and vehicles in crowded environments, and the acquisition of more realistic images for consumer electronics and entertainment. In most of these applications, multiple sensors such as video cameras, infrared (IR), or range sensors gather data from various points of view, which are then sent to a central processing unit. In most existing systems, there is no intelligent processing of the data locally at each camera, and the monitoring stations, which are staffed with people, generally observe and oftentimes store multiple video streams with very limited automated processing. Many fundamental problems need to be solved before these networks can be used more effectively.
