Recently, surveillance systems for public safety have become more intelligent through context awareness. Basically, traditional surveillance systems require power and networking infrastructure to operate the system and to transmit recorded data. These requirements increase the cost of system installation and maintenance. This paper proposes a wireless video sensor network platform for public safety...
Background subtraction is widely used in battery-operated surveillance system. In the system, memory requirement and computational complexity are important issues due to a constraint of the hardware resource. We propose memory-efficient and low computational complexity background subtraction algorithm based on multi-background registration (MBR) technique algorithm.
In this paper surveillance system employing background subtraction scheme is discussed. The aim of the work is to minimize the waste energy of the overall system due to false positives. Pixels in the foreground of a motion detection system remain non-zero even if a moving object has stopped due to the settling time associated with an adaptive background subtraction scheme as Mixture of Gaussians....
Growing needs for surveillance in locations without power lines necessitates the development of a surveillance camera with extremely low-power consumption and an assured stable operation until the time of expected run-out of available energy. This paper proposes an algorithm for scheduling of video encoding configurations in a battery-operated surveillance system to reduce the image distortion while...
We proposed a scheme to improve the lifetime of multi-camera system and the quality of its captured image by appropriate sharing of such resources among camera nodes as battery and memory based on low-power wireless communication links among camera nodes. The proposed scheme determines which camera node captures the event and which camera node stores the captured event by jointly considering residual...
An event criticality-aware wireless surveillance system tries to minimize the energy consumption by adjusting the image distortion (or quality) requirement according to event criticality. In this paper, we present a novel video encoding method which scales bitrate so as to minimize the energy consumption of the wireless surveillance system while satisfying the given memory constraint. Given event...
