Privacy and Trust in Smart Camera Sensor Networks

2015 10th International Conference on Availability, Reliability and Security, 2015
The emerging technologies of Smart Camera Sensor Networks (SCSN) are being driven by the social need for security assurance and analytical information. SCSN are deployed for protection and for surveillance tracking of potential criminals. A smart camera sensor does not just capture visual and audio information but covers the whole electromagnetic ...

The case for multi--tier camera sensor networks

Proceedings of the 15th International Workshop on Network and Operating Systems Support for Digital Audio and Video, 2005
In this position paper, we examine recent technology trends that have resulted in a broad spectrum of camera sensors, wireless radio technologies, and embedded sensor platforms with varying capabilities. We argue that future sensor applications will be hierarchical with multiple tiers, where each tier employs sensors with different characteristics.

Simultaneous Planning, Localization, and Mapping in a Camera Sensor Network

Robotics and Autonomous Systems, 2006
In this paper we examine issues of localization, exploration, and planning in the context of a hybrid robot/camera-network system. We exploit the ubiquity of camera networks to use them as a source of localization data. Since the Cartesian position of the cameras in most networks is not known accurately, we consider the issue of how to localize such ...

An accurate extrinsic camera self-calibration method in non-overlapping camera sensor networks

2011 IEEE International Instrumentation and Measurement Technology Conference, 2011
Accurately extrinsic camera self-calibration, namely determining the positions and orientations of the networked cameras by themselves, is essential for many applications such as surveillance, intelligent environments and traffic monitoring. This paper describes an efficient, range-free and anchor-free method for self-calibrating the extrinsic ...

A Survey on Wireless Camera Sensor Networks

2013
Recently, with the development of low-power and low-complexity hardware such as camera sensors, wireless camera sensor networks have been widely used in the novel field, e.g., smart home and medical. Wireless camera sensor networks can provide richer information such as image and picture during a monitored environment.

On Full-View Area Coverage by Rotatable Cameras in Wireless Camera Sensor Networks

2017 IEEE 31st International Conference on Advanced Information Networking and Applications (AINA), 2017
The paper addresses an area coverage problem by using rotatable cameras in wireless camera sensor networks. It has been recognized as an important issue not only to effectively cover an area of interest without holes but also to identify the object invaded the area by cameras in wireless camera sensor networks.

Full-View Coverage Problems in Camera Sensor Networks

2017
Camera Sensor Networks (CSNs) have emerged as an information-rich sensing modality with many potential applications and have received much research attention over the past few years. One of the major challenges in research for CSNs is that camera sensors are different from traditional scalar sensors, as different cameras from different positions can ...
