Statistical Modeling of Human Interactions

In this paper we describe a real-time computer visionand machine learning system for modeling andrecognizing human behaviors in a visual surveillancetask. The system is particularly concerned with detectingwhen interactions between people occur, andclassifying the type of interaction. Examples of interestinginteraction behaviors include following anotherperson, altering one's path to meet another, and soforth.Our system combines top-down with bottom-up informationin a closed feedback ...
