A New, Integrated Method of Human or Animal Body Modeling with Applications for Animation and Tracking
Stanford researchers have patented a data-driven method for building a human shape model that spans variation in both subject shape and pose. The method is based on a representation that incorporates both articulated and non-rigid deformations.
Capabilities include partial-view completion and lifelike animation of marker motion-capture sequences. Specifically, this method is capable of constructing a high-quality animated surface model of a moving person, with realistic muscle deformation, using just a single static scan and a marker motion capture sequence of the person.
