Description
Systems and Techniques for real-time 3D reconstruction of the human body are described. Avatars (the rendered 3D reconstruction of the human body) can be generated from real-time captured RGB-D images of a person. Avatars can be synthesized from the RGB-D data received from a single RGB-D camera by performing body segmentation (into cylindrical-type objects) and dynamic robust data filtering on sequential frames of the captured data. Cylindrical-type objects of the body, including arms, legs, and torso are parameterized using tensor splines; and positive-definite constrains are imposed to the estimated tensor splines using a Riemannian metric defined on the space of positive-definite tensor splines. These generated avatars have an articulated body with separately translatable and rotatable arms, legs, and other limbs or cylindrical features.
