Video surveillance of interactions

This paper describes an automatic surveillance system, which performs labeling of events and interactions in an outdoor environment. The system is designed to monitor activities in an open parking lot. It consists of three components-an adaptive tracker, an event generator, which maps object tracks onto a set of pre-determined discrete events, and a stochastic parser. The system performs segmentation and labeling of surveillance video of a parking lot and identifies person-vehicle interactions, such as pick-up and drop-off. The system presented in this paper is developed jointly by MIT Media Lab and MIT Artificial Intelligence Lab
