Cylindrical head model estimates a head pose under the assumption that the human head is cylindrical: (a) cylindrical head model; (b) top view of the cylindrical head model where the pose angle is calculated using the three facial lines, namely, the right facial edge, the left facial edge, and the center of the face; (c) selected FFPs for the facial lines and the three lines.
