Pan-Tilt-Zoom (PTZ) cameras are widely used in video surveillance tasks. In particular, they can be used in combination with static cameras to provide high resolution imagery of interesting events in a scene on demand. Nevertheless, PTZ cameras only provide a single trajectory at a time. Hence, engineering algorithms for common computer vision tasks, such as automatic calibration or tracking, f...

OVERVIEW: A camera system is developed for delivering real-time video streams over corporate intranets, the Internet, and other networks. The system encompasses TCP/IP-compliant cameras that can be directly connected to networks, representative application software for the PC side, application-specific APIs, and an environment enabling customers to customize application software. The applicatio...

Transporting camera surveillance data using wireless networks has benefits of reduced cost and increased flexibility. In this paper, we report a measurement study of wireless camera networks using IEEE 802.11 standards, which are pervasively adopted and supported by a large number of vendors. We studied two testbeds deployed in real-world environments, one in a residential house and the other i...

One of the fundamental requirements for visual surveillance using smart camera networks is the correct association of each person’s observations generated on different cameras. Recently, distributed data association that involves only local information processing on each camera node and mutual information exchanging between neighboring cameras has attracted many research interests due to its su...

Camera sensor networks have recently emerged as an important class of sensor networks, where each node is equipped with a camera and has a capability of visually detecting events in its neighborhood. The applications of camera sensor networks are highly diverse, including surveillance, environmental monitoring, smart homes, and telepresence systems. In this article, we focus on one of the key u...
