We present a novel method for the discovery and statistical representation of motion patterns in a scene observed by a static camera. Related methods involving learning of patterns of activity rely on trajectories obtained from object detection and tracking systems, which are unreliable in complex scenes of crowded motion. We propose a mixture model(More)
We describe our experiences with deploying a vehicular Internet access service on public transit buses. Our system, called WiRover, has been running on these buses since April 2010 for about 18 months till date providing a WiFi hotspot to which bus passengers can connect. As of Dec. 1, 2011 we have observed 17,567 unique client devices connect to the(More)
—We propose a technique, called FloMiS, by which a flow can be migrated from one network to another without requiring any changes to the endpoints (Internet-based servers or mobile clients). Our work is motivated by the needs of our vehicular Internet service, called WiRover, through which we provide WiFi connectivity in public transit vehicles — city buses(More)
