[C7] A Low-Power Wireless Image Sensor Node with Noise-Robust Moving Object Detection and a Region-of-Interest Based Rate Controller


This paper presents a low-power wireless image sensor node for military surveillance, with a noise-robust moving object detection and region-of-interest based rate controller. The improved robustness to noise from both environment and hardware further reduces the transmission energy with negligible computation and memory overhead. The rate controller minimizes memory requirement by dynamically tuning the coding parameters for the constant encoding rate.
