1. A method for processing information, comprising:

  • receiving visual information including at least one object in motion;

    locating at least one spatial edge of the object in the visual information;

    generating a plurality of spatio-temporal gradients for the at least one spatial edge over N frames, where N≧

    3;

    generating motion blur images from the spatio-temporal gradients;

    performing a regression analysis on the motion blur images to determine direction of motion information of the object throughout the N frames;

    generating scene activity vectors for the N frames based on the direction of motion information; and

    detecting an event in the visual information based on the scene activity vectors generated for the N frames.
