1. A method of behavior recognition, comprising the steps of: storing a dynamic motion model representative of designated human behaviors in a form of differential equations having position and velocity components; sensing at least one human subject to be analyzed; representing the body of the subject as a plurality of connected, non-deformable links; determining the dynamic motion of the body, if any, by monitoring the position of the links in space as a function of time; using the dynamic motion to derive kinematic link relationships at specific body locations; comparing the kinematic link relationships to the position and velocity components; and, if a match is found, outputting the results of the comparison as the designated behavior.
5. The method of claim 1 , wherein the designated behavior represents a threat.
