摘要：Disclosed herein are a method, system, and computer program product forclassifying a behaviour of a detected object in a video frame, wherein the video frameincludes a plurality of blocks and the detected object is associated with a subset of the
plurality of blocks and a set of parameters. The method includes the step of associatinga behaviour model with each of the plurality of blocks, wherein each behaviour model ()includes a set of behaviour modes (). The method then performs the steps, for eachblock in the video frame associated with the detected object, of: (i) determining a set ofbehaviour statistics associated with the detected object, based on the detected objectand the set of parameters; and (ii) comparing the determined set of behaviour statisticswith each behaviour mode in the set of behaviour modes associated with that block () todetermine an abnormality measure associated with the block (). The method thenclassifies the behaviour of the detected object based on the abnormality measuresassociated with the subset of the plurality of blocks associated with the detected object.
