A sequential set of 2D stick figures is used to represent the human gait motion, and the features based on motion parameters are determined from the sequence of extracted gait figures. ...
The automated system consists of three stages: i) detection and extraction of the moving human body and its contour from image sequences, ii) extraction of gait figures by the joint angles and body points ...
The simplified 2D stick figure model, with six joint angles, is closely related to the observation that human motion is essentially the movement of the human skeleton; thus, the stick figure can be described ...
