A Bio-Inspired Vision Sensor With Dual Operation and Readout Modes [PDF]
This paper presents a novel event-based vision sensor with two operation modes: intensity mode and spatial contrast detection. They can be combined with two different readout approaches: pulse density modulation and time-to-first spike.

Approximate Initialization of Camera Sensor Networks [PDF]
Camera sensor networks--wireless networks of low-power imaging sensors-have become popular recently for monitoring applications. In this paper, we argue that traditional vision-based techniques for calibrating cameras are not directly suitable for low-power sensors deployed in remote locations.

Camera Sensor Activation Scheme for Target Tracking in Wireless Visual Sensor Networks
Target tracking has become an elementary task in wireless visual sensor networks (WVSNs). In this paper, we propose a camera sensor activation scheme for target tracking in WVSN.

The Coverage Problem in Video-Based Wireless Sensor Networks: A Survey
Wireless sensor networks typically consist of a great number of tiny low-cost electronic devices with limited sensing and computing capabilities which cooperatively communicate to collect some kind of information from an area of interest.

Sensor node localisation using a stereo camera rig [PDF]
In this paper, we use stereo vision processing techniques to detect and localise sensors used for monitoring simulated environmental events within an experimental sensor network testbed.

On full-view coverage in camera sensor networks [PDF]
Camera sensors are different from traditional scalar sensors as different cameras from different positions can form distinct views of the object. However, traditional disk sensing model does not consider this intrinsic property of camera sensors. To this end, we propose a novel model called full-view coverage.

Abnormal Behavior Detection Using Trajectory Analysis in Camera Sensor Networks
Camera sensor networks have developed as a new technology for the wide-area video surveillance. In view of the limited power and computational capability of the camera nodes, the paper presents an abnormal behavior detection approach which is convenient ...
