With recent advances in consumer electronics and the increasingly urgent need for public
security, camera networks have evolved from their early role of providing simple and static …

Given a delimited surveillance area, represented in either 2D or 3D, and a set of feasible
camera locations and orientations, the optimal camera placement problem (OCP) is that of …

As a consequence of increasing safety concerns, camera surveillance has been widely
adopted as a way to monitor public spaces. One of the major challenges of camera …

Public transport safety is an important issue that has recently gained substantial attention,
especially with the increasing number of violent incidents occurring abroad. To avoid such …

This paper presents a novel approach to increasing the information content in sensor
measurements, with special applications in images or video. The entropy of a signal gives a …

This paper presents a novel approach to increase the amount of visual stimuli in sensor
measurements using saliency maps. A saliency map is a combination of normalized feature …

Sky monitoring has many applications but also many challenges to be addressed before it
can be realized. Some of the challenges are cost, energy consumption and complex …

This paper considers the problem of a reconnaissance mission in which a single multirotor
drone must survey a given map by repetitively visiting different checkpoints. Several points …

In recent years, video surveillance technology has been developing. The use of video
surveillance has spread from national and social welfare to everyday life, and a number of …

Due to the impact of optimal camera placement on the efficiency and the cost of surveillance
systems as well as the rapid development in sensor technologies and the pressing security …
