Patent ID: 7447334

Claim:
A motion recognition system for distinguishing motion between two different entity forms, comprising: a moving object detection component, configured to detect a moving object in a video sequence and generate a moving object signal; a motion feature extraction component, configured to receive the moving object signal and to generate a motion representation, generate space-time correlations of the motion representation, and generate statistics of the space-time correlations for the detected object within the object signal, where the statistics of the space-time correlations are two statistics, Renyi Entropy and mean value, with the two statistics calculated as motion features; and a motion feature classification component, configured to receive and classify the features extracted from the detected object as either a first entity motion or a second entity motion, and to generate an identification signal, whereby through detecting, extracting and classifying the object, it is determined if the object is either a first entity form or a second entity form.
