An energy-efficient and highly accurate change detection method for a vehicular black box system by utilising information in a compressed domain is presented. Studies have shown that most automobiles spend a substantial percentage of time parked rather than driven. Thus, minimising energy consumption in a parked mode is crucial for vehicular black box systems design to prevent the battery being fully...
In battery-operated wireless video surveillance systems (WVSS), it is mostly required to detect events in an energy-efficient manner due to limited available energy and a huge amount of data to be processed. Therefore, one of the main challenges in the battery-constrained systems is to minimize the energy consumption of the whole system. In this paper, we present an energy-aware event detector which...
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...
