An mpeg movie showing tracking of an articulated structure with a prismatic (sliding) joint. | |

An mpeg movie showing tracking of a doubly hinged structure.
This movie shows that even when the central square piece is hidden from the camera, the system can still recover its pose, despite the fact that it forms the root node of the kinematic chain/tree. This is achieved by making use of the constraints that exist between it and the other two pieces. |
