  • Video-based motion capture and adaptation
    Patent number: 9322653
    Abstract: The disclosure provides an approach for estimating a state-space controller from a set of video frames depicting a motion of an entity. The approach includes incrementally optimizing parameters of the state-space controller and changing a structure of the state-space controller based on expanding subsets of the set of video frames. In one embodiment, a controller-estimation application greedily selects, at every stage of the incremental optimization, structure and parameters of the controller which minimize an objective function. In another embodiment, the controller-estimation application re-optimizes, after the incremental optimization, all parameters of the state-space controller based on all of the video frames.
