First Claim
Patent Images
1. A method for modeling a three-dimensional (3D) face, the method comprising:
- setting a predetermined reference 3D face to be a working model, and tracking a face, based on the working model;
generating a result of the tracking including at least one of a face characteristic point, an expression parameter, and a head pose parameter from a video frame;
updating the working model, based on the result of the tracking.

Abstract
A method and apparatus for modeling a three-dimensional (3D) face, and a method and apparatus for tracking a face. The method for modeling the 3D face may set a predetermined reference 3D face to be a working model, and generate a result of tracking including at least one of a face characteristic point, an expression parameter, and a head pose parameter from a video frame, based on the working model, to output the result of the tracking.
