Method and system for analyzing human behavior in an intelligent surveillance system

摘要

A method for analyzing behavior in an intelligent surveillance system, the system being operable to provide a series of consecutive images of an area under surveillance for consecutive time points (801), the method comprising the steps of: for each image of the series, generating a set of points defining at least one moving silhouette (802) on an image; tracing the position of points in the sets of points (803) on consecutive images in order to generate trajectories of points (804); providing a database of predefined trajectories corresponding to behavior (805); comparing the generated trajectories of points for said moving silhouette with database records (806); outputting (807) information regarding the type of predefined behavior said moving silhouette corresponds to.
