In real-time video streaming applications based on battery-powered camera systems, it is crucial to capture and transmit critical information satisfying the storage capacity and channel bandwidth requirement. In this paper, we propose a single-pass content-aware video encoding scheme for such applications to achieve a consistent video quality while satisfying the bit-rate constraints. To achieve the...
In this paper, we propose an event-driven black box surveillance camera which reduces energy consumption by waking up the system only when an event is detected and dynamically adjusting the video encoding and the resultant image distortion according to the criticality of captured frames called significance level. To achieve this goal, we find an encoding bitrate minimizing the energy consumption of...
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...
