Description
Summary:This paper describes a real-time application programmed into Wi-FLIP, a wireless smart camera resulting from the integration of FLIP-Q, a prototype mixed-signal focal-plane array processor, and Imote2, a commercial WSN platform. The application consists in scanning the whole scene by sequentially analyzing small regions. Within each region, motion is detected by background subtraction. Subsequently, information related to that motion - intensity and location - is radio-propagated in order to remotely account for it. By aggregating this information along time, a motion map of the scene is built. This map permits to visualize the different activity patterns taking place. It also provides an elaborated representation of the scene for further remote analysis, preventing raw images from being transmitted. In particular, the scene inspected in this demo corresponds to vehicular traffic in a motorway. The remote representation progressively built enables the assessment of the traffic density.
