Demo: Mouse sensor networks, the smart camera
2011 Fifth ACM/IEEE International Conference on Distributed Smart Cameras, 2011This 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.

Automated calibration of a camera sensor network
2005 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2005In this paper we present a new approach for the online calibration of a camera sensor network. This is the first step towards fully exploiting the potential for collaboration between mobile robots and static sensors sharing the same network. In particular we propose an approach for extracting the 3D pose of each camera in a common reference frame, with

Collaborative Target Localization in Camera Sensor Networks
2008 IEEE Wireless Communications and Networking Conference, 2008Target 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.

Traffic modeling and prediction using camera sensor networks
Proceedings of the Fourth ACM/IEEE International Conference on Distributed Smart Cameras, 2010We propose a Bayesian framework for modeling and predicting traffic patterns using information obtained from wireless sensor networks. For concreteness, we apply the proposed framework to a smart building application in which traffic patterns of humans are modeled and predicted through detection and matching of their images taken from cameras at ...

A simulation framework for camera sensor networks research
Proceedings of the 11th communications and networking simulation symposium, 2008We present our progress on the Virtual Vision paradigm, which prescribes visually and behaviorally realistic virtual environments, called "reality emulators", as a simulation tool to facilitate research on large-scale camera sensor networks. We have successfully exploited a prototype reality emulator---a virtual train station populated with numerous ...

Energy Efficient Object Detection in Camera Sensor Networks
2017 IEEE 37th International Conference on Distributed Computing Systems (ICDCS), 2017A 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.

DSPcam: A camera sensor system for surveillance networks
2009 Third ACM/IEEE International Conference on Distributed Smart Cameras (ICDSC), 2009Surveillance is emerging as a key application of camera networks. In this paper, we describe our wireless smart camera system called DSPcam designed for real-time surveillance purposes. DSPcam has a Blackfin processor, CMOS image sensor and 802.11 b/g communication module.

Achieving full-view coverage in camera sensor networks
ACM Transactions on Sensor Networks, 2013Camera sensors are different from traditional scalar sensors, as cameras at different positions can form very different views of the object. However, traditional coverage model does not consider this intrinsic property of camera sensors. To address this issue, a novel model called full-view coverage is proposed.

On Barrier Coverage in Wireless Camera Sensor Networks
2010 24th IEEE International Conference on Advanced Information Networking and Applications, 2010The paper proposed a distributed algorithm, namely CoBRA (Cone-based Barrier coveRage Algorithm), to achieve barrier coverage in wireless camera sensor networks (WCSNs). To the best understanding, CoBRA is the first algorithm which try to deal with the barrier coverage issue in WCSNs.
