Abstract
A method of estimating a pose of a head for a person, includes estimating the pose of the head for the person based on a content, and generating a three-dimensional (3D) model of a face for the person. The method further includes generating pictorial structures of the face based on the estimated pose and the 3D model, and determining a refined pose of the head by locating parts of the face in the pictorial structures.
Claims20
A method of estimating a refined pose of a head for a person,
- the method comprising:
- estimating a rough pose of the head for the person based on a two-dimensional (2D) image;
- generating a three-dimensional (3D) model of a face for the person;
- rotating the 3D model based on the estimated rough pose;
- determining parts of the face from the rotated 3D model;
- projecting the rotated 3D model and the determined parts of the face to a 2D model;
- and
- determining the refined pose of the head based on the 2D model.
