ALERT VOLUME NORMALIZATION IN A VIDEO SURVEILLANCE SYSTEM
First Claim
1. A method for normalizing and publishing an alert generated by a behavioral recognition system, the method comprising:
- receiving an alert having a type and an original rareness value,converting the original rareness value to an alert percentile value,upon determining that the alert percentile value is greater than a percentile threshold, normalizing the alert, andpublishing the alert.

Abstract
Techniques are disclosed for normalizing and publishing alerts using a behavioral recognition-based video surveillance system configured with an alert normalization module. Certain embodiments allow a user of the behavioral recognition system to provide the normalization module with a set of relative weights for alert types and a maximum publication value. Using these values, the normalization module evaluates an alert and determines whether its rareness value exceed a threshold. Upon determining that the alert exceeds the threshold, the module normalizes and publishes the alert.
