Monocular 3D tracking of the golf swing

This paper showcases our tracking algorithm described in (R. Urtasun et al., 2005). The proposed approach incorporates dynamic motion models into the human body tracking process yielding full 3D reconstruction from monocular sequences. The tracking is formulated in terms of minimizing a differentiable criterion whose differential structure is rich enough for successful optimization using a single hypothesis. In other words we avoid the computational complexity of multihypotheses algorithms while obtaining excellent results under challenging conditions.
