Temporal Filter Parameters for Motion Pattern Maps

  • O'Gorman L.

There are many video analysis applications in which the flow of people or traffic over time is of more interest than tracking the discrete objects contained. Motion pattern maps, loosely called heat maps, can show accumulated activity over time via temporal filtering. In this paper, we examine three parameters that ...

The increasing popularity of jumbo frames means growing variance in the size of packets transmitted in modern networks. Consequently, network monitoring tools must maintain explicit traffic volume statistics rather than settle for packet counting as before. We present constant time algorithms for volume estimations in streams and sliding windows, which ...
