[C1] Adaptive Wireless Video Sensor Node Using Content-Aware Pre-Processing for Moving Target Identification

Abstract

In this paper, an adaptive wireless video sensor node for surveillance applications is designed using content-aware pre-processing. A low-overhead pre-processing engine detects the region-of-interest (ROI) in a frame defined as the macroblocks with moving objects. Under varying wireless channel condition, energy- and content-aware control maintains system energy with reducing the quality degradation of ROI. Compared to the existing systems, the proposed system consumes up to 56% less energy at the same quality.
