Patent 7447334 was granted and assigned to Hrl Laboratories, Llc on November, 2008 by the United States Patent and Trademark Office.
The present invention relates to a motion recognition system for distinguishing motion between two different entity forms, such as distinguishing human motion from animal motion. The motion recognition system comprises a moving object detection component, a motion feature extraction component, and a motion feature classification component. The moving object detection component is configured to detect an object within a video sequence and generate a moving object signal. The motion feature extraction component is configured to receive the moving object signal and to extract features representing the detected object within the object signal. The motion feature classification component is configured to classify the features extracted from the detected object as either human motion or animal motion, thereby generating an identification signal. Through detecting, extracting and classifying the objection, a user can determine if the object is a human or an animal.
