Barrier coverage in camera sensor networks [PDF]

open access: yesProceedings of the Twelfth ACM International Symposium on Mobile Ad Hoc Networking and Computing, 2011
Barrier coverage has attracted much attention in the past few years. However, most of the previous works focused on traditional scalar sensors. We propose to study barrier coverage in camera sensor networks. One fundamental difference between camera and scalar sensor is that cameras from different positions can form quite different views of the object.

Distributed compression in camera sensor networks [PDF]

open access: yesIEEE 6th Workshop on Multimedia Signal Processing, 2004., 2005
We address the problem of distributed compression in camera sensor networks. Our approach uses some geometrical information in order to estimate the correlation in the visual data. This correlation, which is related to the structure of the plenoptic function, can then be used to reduce the overall transmission rate from the sensors to a common central ...

Distributed calibration of Camera Sensor Networks [PDF]

open access: yes2009 Third ACM/IEEE International Conference on Distributed Smart Cameras (ICDSC), 2009
We propose a distributed algorithm for calibrating the intrinsic and extrinsic parameters of a Camera Sensor Network (CSN). We assume that only one of the cameras is calibrated and that the network graph, i.e. the graph over which the cameras communicate, is connected.

Cooperative Target Tracking by Multiagent Camera Sensor Networks via Gaussian Process

open access: yesIEEE Access, 2022
In this paper, we present learning-based robust cooperative control for camera sensor networks. The dynamics of each camera agent with the pan and tilt mechanism is modeled by the Euler-Lagrange equation.

An Intra-Vehicular Wireless Multimedia Sensor Network for Smartphone-Based Low-Cost Advanced Driver-Assistance Systems

open access: yesSensors, 2022
Advanced driver-assistance system(s) (ADAS) are more prevalent in high-end vehicles than in low-end vehicles. Wired solutions of vision sensors in ADAS already exist, but are costly and do not cater for low-end vehicles. General ADAS use wired harnessing

Neural Network Generalization: The Impact of Camera Parameters

open access: yesIEEE Access, 2020
We quantify the generalization of a convolutional neural network (CNN) trained to identify cars. First, we perform a series of experiments to train the network using one image dataset - either synthetic or from a camera - and then test on a different ...

On full-view coverage in camera sensor networks [PDF]

open access: yes2011 Proceedings IEEE INFOCOM, 2011
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.

Barrier Coverage for 3D Camera Sensor Networks [PDF]

open access: yesSensors, 2017
Barrier coverage, an important research area with respect to camera sensor networks, consists of a number of camera sensors to detect intruders that pass through the barrier area. Existing works on barrier coverage such as local face-view barrier coverage and full-view barrier coverage typically assume that each intruder is considered as a point ...

Sensor node localisation using a stereo camera rig [PDF]

open access: yes, 2007
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.

Radar Voxel Fusion for 3D Object Detection

open access: yesApplied Sciences, 2021
Automotive traffic scenes are complex due to the variety of possible scenarios, objects, and weather conditions that need to be handled. In contrast to more constrained environments, such as automated underground trains, automotive perception systems ...
