3. The method of claim 2 wherein determining an optimal matching comprises steps of: representing the current frame by a human body model comprising coordinates of joints and body parts having shapes associated with limbs, torso and head; representing each pose prediction in the high dimensional space by the human body model; and selecting the pose prediction that optimally matches to the current frame based on the human body model.
