This paper evaluates the accuracy of several RSSI-based localization techniques on a live
jobsite and compares them to results obtained in an operating building. RSSI-based …

Person re‐identification across different surveillance cameras with disjoint fields of view has
become one of the most interesting and challenging subjects in the area of intelligent video …

Conventional tracking approaches assume proximity in space, time and appearance of
objects in successive observations. However, observations of objects are often widely …

When viewed from a system of multiple cameras with non-overlapping fields of view, the
appearance of an object in one camera view is usually very different from its appearance in …

The high complexity of modern large‐scale construction projects leads their schedules to be
sensitive to delays. At underground construction sites, the earthwork processes are vital, as …

We describe a method for simultaneously recovering the trajectory of a target and the
external calibration parameters of non-overlapping cameras in a multi-camera system. Each …

In this article, we present Knight, an automated surveillance system deployed in a variety of
real-world scenarios ranging from railway security to law enforcement. We also discuss the …

We propose a visual search engine (ViSE) as a semi-automatic component in a surveillance
system using networked cameras. The ViSE aims to assist the monitoring operation of huge …

Many distributed multimedia applications rely on video analysis algorithms for automated
video and image processing. Little is known, however, about the minimum video quality …

This paper presents our research towards smart camera networks capable of carrying out
advanced surveillance tasks with little or no human supervision. A unique centerpiece of our …
