Trusted Video Streams in Camera Sensor Networks

2020 IEEE 18th International Conference on Embedded and Ubiquitous Computing (EUC), 2020
Proof of integrity in produced video data by surveillance cameras requires active forensic methods such as signatures, otherwise authenticity and integrity can be comprised and data becomes unusable e. g. for legal evidence. But a simple file- or stream-signature loses its validity when the stream is cut in parts or by separating data and signature ...

Optimal camera selection for target localization in camera sensor networks

2008 42nd Annual Conference on Information Sciences and Systems, 2008
In this paper, we address the problem of localization-oriented optimal cameras selection based upon a tradeoff between the accuracy of target localization and the energy consumption in camera sensor networks. We model the addressed problem into the combined optimization problem of selecting a sequence of sets to minimize the cost while achieving a ...

Minimum camera barrier coverage in wireless camera sensor networks

2012 Proceedings IEEE INFOCOM, 2012
Barrier coverage is an important issue in wireless sensor network. In wireless camera sensor networks, the cameras take the images or videos of target objects, the position and angle of camera sensor impact on the sense range. Therefore, the barrier coverage problem in camera sensor network is different from scalar sensor network.

Energy Efficient Object Detection in Camera Sensor Networks

2017 IEEE 37th International Conference on Distributed Computing Systems (ICDCS), 2017
A wireless camera network can provide situation awareness information (e.g., humans in distress) in scenarios such as disaster recovery. If such camera sensors are battery operated, sending raw video feeds back to a central controller can be expensive in terms of energy consumption.

Demo: Mouse sensor networks, the smart camera

2011 Fifth ACM/IEEE International Conference on Distributed Smart Cameras, 2011
This paper describes an extremely low-cost smart camera with imaging sensor, freely programmable DSP, power control and wired/wireless networking capabilities. The power consumption reaches from 3mW to 240mW depending on load and transmission rates and the BOM for a single device is now 25 euros.

LCPR: A Multi-Scale Attention-Based LiDAR-Camera Fusion Network for Place Recognition

IEEE Robotics and Automation Letters, 2023
Place recognition is one of the most crucial modules for autonomous vehicles to identify places that were previously visited in GPS-invalid environments. Sensor fusion is considered an effective method to overcome the weaknesses of individual sensors. In

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 ...

Collaborative Target Localization in Camera Sensor Networks

2008 IEEE Wireless Communications and Networking Conference, 2008
Target localization is an important application in sensor networks. Although the localization problem in acoustic /radar sensor networks has been intensively studied, few consider the problem in camera sensor networks. In this paper, we propose a method to utilize the active cameras to localize the target collaboratively.

Unraveling Impact of Critical Sensing Range on Mobile Camera Sensor Networks

IEEE Transactions on Mobile Computing, 2020
In camera sensor networks (CSNs), full view coverage, meaning that any direction of any point in the operational region is covered by at least one camera sensor, plays a significant role in object identification.

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.
