The paper is a survey of the main technological aspects of advanced visual-based
surveillance systems. A brief historical view of such systems from the origins to nowadays is …

A real-time active system able to monitor wide areas by processing video sequences
acquired by a pan, tilt, and zoom (PTZ) camera is presented. The system is able to …

This survey describes the current state-of-the-art in the development of automated visual
surveillance systems so as to provide researchers in the field with a summary of progress …

Visual sensors have characteristics that make them interesting as sources of information for
any process or system. On the one hand, they are able to capture a very precise and high …

The integration of video technology and sensor networks constitutes the fundamental
infrastructure for new generations of multimedia surveillance systems, where many different …

This work aims to present an intelligent system for tracking moving targets (such as vehicles,
persons etc) based on a network of distributed autonomous units that capture and process …

Vision systems in quality control are increasingly widespread but are currently suffering from
limitations in certain applications which concern their processing capability as well as their …

The task of large-area visual monitoring for the protection of critical and public infrastructures
calls for reliable automated visual surveillance systems. Reliability in this context implies that …

The problem of automated visual surveillance has spawned a lively research area, with
2005 seeing three conferences or workshops and special issues of two major journals …

In the last two decades, visual sensor networks have been developed to gather visual data
from different monitoring scenarios, directly contributing to the maturation of the Internet of …
