Usually multiple camera networks are employed to cover, monitor and improve the safety of people in large multifunctional crowded buildings.
As the main advantage of the presented approach is a low barrier improvement to forest cover monitoring in highly clouded areas, it should be noted that other technologies, such as InSAR (Interferometric synthetic aperture radar) also hold great value for observation of forest cover in highly cloudy regions.
This seems to be like a big area to cover for monitoring crowd.
At present, a kind of widely used strategy is choosing part nodes which can be enough to cover the monitoring area as working nodes, at the same time, turn off redundant nodes [23].
An automated, satellite-based snow mapping system has been developed at NOAA/NESDIS to provide operational snow cover monitoring over the North American continent.
In addition, a piece of black cardboard with a circular aperture (diameter = 17°) was used to cover the monitor to exclude the possibility that subject could utilize the edges of the monitor to perform the orientation discrimination task.
As an extreme example, a 2003 report by the Utah Insurance Department showed that, prior to the passage of Utah's 2000 law requiring insurers to cover diabetic monitors and blood testing strips, all insurance plans in the state already provided such coverage [ 23].
The high-resolution satellite-based tree cover monitoring products would be useful and strengthen third-party level evaluations.
In Queensland, Australia, a number of government policies, natural resource management programmes and research activities are reliant on large-area, multi-temporal land cover monitoring applications based on Landsat satellite imagery.
In order to solve the problem, a parallel network of multiple cameras is commonly used to cover the panoramic monitoring area [1].
