After calculating the flow blobs, we use a rule-based technique to identify an action. The action rules use the about the motion blobs: the information following number of blobs, the direction and magnitude of motion within the blobs, the relative motion between blobs, the relative size of the blobs, and the relative positions of the waving, clapping, jumping, drumming, flapping, and marching are currently recognized. Once the motion is recognized, the system
