A SYSTEM AND METHOD TO DETECT HUMAN LOITERING ACTIVITY USING TRAJECTORY INFORMATION

摘要

The present invention provides a method for detecting loitering event in a region of interest. The method comprises the steps of determining presence of at least one object in region of interest, tagging each object of interest with identity, computing total time stamp for each object of interest, determining time span of each object of interest based on trajectory information and speed profile, detecting loitering event based on combination of plurality of the determined features and triggering alert when loitering event is detected.
