visual sensor network

(redirected from Camera sensor network)

visual sensor network

A network of wired or wireless video cameras distributed throughout a building or outdoor area that provides a continuous surveillance of the environment. A visual sensor network (VSN) presents a coherent picture of the environment to the user rather than just a collection of individual video clips. Preprocessing often takes place within the "smart" cameras before sending the data to a central computer that performs additional processing. See computer vision.

In the case of camera sensor networks, some simulation tools allow important network simulation issues [11] and image quality assessment [12], generally using simplified abstract models.
In the camera sensor networks field, TinyOS has been used as the operating system of the Cyclops camera [15], a low-cost image sensor capable of being connected to a Crossbow mote such as Mica2.
Some studies have been conducted about target-tracking and node-scheduling algorithms for camera sensor networks. Alberto et al.
All the aforementioned target-tracking and node-scheduling algorithms for camera sensor networks do not involve the usage of compressed sensing theory.
Cao, "Achieving full-view coverage in camera sensor networks," ACM Transactions on Sensor Networks, vol.
Wang and Cao [23] introduced a novel full-view coverage model to camera sensor networks. Further, a novel method to select camera sensor nodes from an arbitrary deployment was suggested in [24] to form a camera barrier.
Camera sensor networks consist of low-power microcamera nodes, which integrate the image sensor, embedded processor, and wireless transceiver.
