Abstract

A system for recognizing various human and creature motion gaits and behaviors is presented. These behaviors are defined as combinations of “gestures” identified on various parts of a body in motion. For example, the leg gestures generated when a person runs are different than when a person walks. The system described here can identify such differences and categorize these behaviors. Gestures, as previously defined, are motions generated by humans, animals, or machines. Multiple gestures on a body (or bodies) are recognized simultaneously and used in determining behaviors. If multiple bodies are tracked by the system, then overall formations and behaviors (such as military goals) can be determined.

Claims

1. A method of behavior recognition, comprising the steps of:

modeling general kinematic relationships associated with a body;

modeling and parameterizing specific link combinations for portions of the body; and

developing a link representation and dynamic model for the entire body based upon the specific link combinations.

2. The method of claim 1, wherein the body is a human being.

3. The method of claim 1, wherein the body is a group of people.

4. The method of claim 1, wherein the body is a human hand.

5. The method of claim 1, wherein the body is a vehicle.

6. The method of claim 1, wherein the body is a weapon.

7. The method of claim 1, wherein the body forms part of a robot.
