Abstract:
1. A method for the analysis of a sequence of captured images showing a scene for detecting and tracking of at least one moving or static object and for matching behavior patterns of the at least one moving or static object in the captured images to object behavior in predetermined scenarios, the method comprising the steps of: capturing an at least one long term reference image representing a background of a scene, an at least one short term reference image representing the background of the scene and an at least one static object within the scene, and an at least one current image of the scene; pre-processing the at least one current image of the scene for generating a long term difference image between the at least one long term reference image and the at least one current image of the scene, and a short term difference image between the short term reference image and the at least one current image of the scene; and clustering the at least one moving or static object from the short term difference image and the long term difference image and generating at least one new object and at least one existing object, the step of clustering comprising: adjusting the parameters of each of the at least two dynamic or static objects clustered within each group; and updating the parameters and status of each of the at least two dynamic or static objects.
