Inference topology of distributed camera networks with multiple cameras
Multimedia Tools and Applications, 2012This paper proposes an inference method to construct the topology of a camera network with overlapping and non-overlapping fields of view for a commercial surveillance system equipped with multiple cameras. It provides autonomous object detection, tracking and recognition in indoor or outdoor urban environments. The camera network topology is estimated

Autoconfiguration of a Dynamic Nonoverlapping Camera Network
IEEE Transactions on Systems, Man and Cybernetics, Part B (Cybernetics), 2007In order to monitor sufficiently large areas of interest for surveillance or any event detection, we need to look beyond stationary cameras and employ an automatically configurable network of nonoverlapping cameras. These cameras need not have an overlapping field of view and should be allowed to move freely in space. Moreover, features like zooming in/

Self-Reconfigurable Smart Camera Networks
Computer, 2014Camera networks that reconfigure while performing multiple tasks have unique requirements, such as concurrent task allocation with limited resources, the sharing of data among fields of view across the network, and coordination among heterogeneous devices.

Asynchronous distributed calibration of camera networks
2013 European Control Conference (ECC), 2013This work focuses on the problem of calibrating planar networks of cameras in a distributed fashion. The camera network is modeled by a graph, and along each edge a noisy relative angular measurement is available. The goal is to achieve the absolute orientation of each camera with respect to a fixed external reference frame, in order to be able to ...

Autonomous calibration algorithms for networks of cameras
2012 American Control Conference (ACC), 2012We deal with the important applicative problem of distributed cameras calibration. We model a network of N cameras as an undirected graph in which communicating cameras can measure their relative orientation in a noisy way. These measures can be used in order to minimize a suitable cost function.

Photography and Culture, 2017
AbstractDespite increasing interest in visual studies, diaspora studies, and oral history, critics have not fully accounted for the complexity of family photography. The Family Camera is a collaborative research project that collects domestic images and oral histories about them as a means of tracing new histories of migration.

OptiCam: Optimal Camera Selection for Provisioning Camera - Network -as-a -Service
GLOBECOM 2020 - 2020 IEEE Global Communications Conference, 2020This work proposes an optimal camera selection scheme, OptiCam, for provisioning Camera-Network-as-a-Service (CNaaS) to multiple end-users while ensuring fair participation of the camera-network owners. Typically, in CNaaS, multiple cameras work together to form a virtual camera network and provide the services to the end-users.

Minimum camera barrier coverage in wireless camera sensor networks
2012 Proceedings IEEE INFOCOM, 2012Barrier 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.

A fuzzy model for coverage evaluation of cameras and multi-camera networks
Proceedings of the Fourth ACM/IEEE International Conference on Distributed Smart Cameras, 2010A comprehensive, intuitive, task-oriented three-dimensional coverage model for cameras and multi-camera networks using fuzzy sets is presented. The model captures the vagueness inherent in the concept of visual coverage. At present, the model can be used to evaluate, given a scene model and an objective, the coverage performance of a given camera or ...

Sensor Localization and Camera Calibration in Distributed Camera Sensor Networks
2006 3rd International Conference on Broadband Communications, Networks and Systems, 2006Camera sensors constitute an information rich sensing modality with many potential applications in sensor networks. Their effectiveness in a sensor network setting however greatly relies on their ability to calibrate with respect to each other, and other sensors in the field. This paper examines node localization and camera calibration using the shared
