System and Methods for Improving Accuracy and Robustness of Abnormal Behavior Detection
First Claim
1. A surveillance system that improves accuracy and robustness of abnormal behavior detection of a monitored object traversing a space comprising:
- a model building processing circuit receiving attributes of the object and building at least one normal motion model;
a behavior assessment processing circuit receiving the at least one normal motion model and scoring at least one of a wrong direction behavior, a wandering behavior and a speeding behavior to thereby define a score; and
an alarm generation processing circuit generating an alarm according to the score.

Abstract
A surveillance system which improves accuracy and robustness of abnormal behavior detection of a monitored object traversing a space includes a metadata processing module, a model building module, and a behavior assessment module. The metadata processing module generates trajectory information for a monitored object and determines attributes of the monitored object. The model building module generates and updates normal motion models based on at least one of the trajectory information, the attributes, and an abnormal behavior score. The behavior assessment module generates the abnormal behavior score based on one of a plurality of methods. A first one of the plurality of methods defines wrong direction behavior. A second one of the plurality of methods defines wandering/loitering behavior. A third one of the plurality of methods defines speeding behavior.
