Visual surveillance in a dynamic and uncertain world

Fully Distributed Secure Video Surveillance Via Portable Device with User Awareness

“…The Computer Vision, can be considered as a process constituted by a number of phases that may vary, depending on the operating scenario and the specific system application domain. Such phases, can be typically grouped into four main blocks, which are image preprocessing, object recognition with motion detection, object monitoring and reasoning with activity recognition [29], [5], [4], [2].…”

“…The new generation video surveillance systems, are concerned with the monitoring of permanent and transients objects within a given area or environment, both indoor and outdoor [2], [3], [4], [5] and typically rely on Computer Vision techniques [6], [7], [8] [9]. By using such techniques, our system is able to automatically interpret the scene, as well as to understand and predict actions and interactions taking place among the observed objects, based on the information acquired by the involved observation camera(s).…”

Active recognition through next view planning: a survey

“…9. A task-specific belief network in the system of Buxton and Gong [83] (Figure 6 on page 448). This belief network captures dependent relationships between the scene layout and relevant measures in motion segmentation and tracking, for their traffic surveillance application.…”

“…Buxton and Gong [83] present a visual surveillance system for tracking moving objects and interpreting their patterns of behaviour. They use conceptual knowledge of both the scene and the visual task to provide constraints to the problem.…”

“…In their system for 3-D reconstruction of static scene, Marchand and Chaumette [78] propose a prediction/verification scheme using decision theory and Bayes nets. The visual surveillance system of Buxton and Gong [83] uses many different representations for its components, such as Bayes nets and ground plane maps. Artificial neural networks form the architecture of systems that use some form of learning, such as those of Baluja and Pomerleau [82], and Thrun [92].…”
