Abstract
A method, system, and computer program product for classifying a behavior of a detected object in a video frame, wherein the video frame includes a plurality of blocks and the detected object is associated with a subset of the plurality of blocks. The method includes the step of associating a behavior model with each of the plurality of blocks, wherein each behavior model includes a set of behavior modes each having a set of parameters. The method further includes the steps, for each block in the video frame associated with the detected object, of: (i) determining a set of behavior statistics associated with the detected object, based on the detected object and the set of parameters; and (ii) comparing the determined set of behavior statistics with the set of parameters of each behavior mode in the set of behavior modes associated with that block to determine an abnormality score. The method also includes the step of classifying the behavior of the detected object based on the abnormality scores associated with the subset of the plurality of blocks associated with the detected object.
