Describes the fundamental structures that interlink and constitute a body and specifies their constraints: e.g., torso and upper leg are linked by the hip, upper leg and lower leg are linked by the knee, and the knee constrains the degree of freedom of the lower leg. Therefore, it also defines the dependency of one body segment to another. Structural model is normally used together with a motion model to guide feature (of motion) extraction process. It may also consist of information such as length, thickness, area, or volume.
