Figure 12: Upper body results. (a) Original sequence. (b, c) The final results after one tracking run to roughly adjust
the posture and a fitting run to refine the skeleton and metaball proportions and the posture. The center row (b) depicts a
discreet visualization of the metaballs and the bottom row (c) shows the smoothly rendered implicit surface.
