Example text

Each joint in the human skeleton model has 3 DOFs which quantify its rotation in its p a r e n t ' s local coordinate frame. Due to biomechanical constraints, each DOF has its own valid range. The root joint has another 3 D O F s , namely, its translation in the world coordinate. In pose recovery step, we consider pose as the vector of all joints' rotations including root. The r o o t ' s translation is not included since it is the f i g u r e ' s global position instead of pose configuration. Next we formulize the object function E ( p ' ) .

Figs. 24 show the results for this clip at the 1st, 5th, 17th, 26th and 39th frames. It is well known to the audience of that movie that in this clip the dancing is performed at a very high speed with significant displacement of limbs. Our system can successfully track such fast motion. Fig. 20 Clip from Mask at the 1st frame 2 Natural Video-based Human Motion Capture Fig.
