    Abstract: A face tracking apparatus includes: a face region detector; a segmentation unit; an occlusion probability calculator; and a tracking unit. The face region detector is configured to detect a face region based on an input image. The segmentation unit is configured to segment the face region into a plurality of sub-regions. The occlusion probability calculator configured to calculate occlusion probabilities for the plurality of sub-regions. The tracking unit is configured to track a face included in the input image based on the occlusion probabilities.

    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.

    Abstract: Provided is a method and apparatus of extracting a 3D facial expression of a user. When a facial image of the user is received, the 3D facial expression extracting method and apparatus may generate 3D expression information by tracking an expression of the user from the facial image using at least one of shape-based tracking and texture-based tracking, may generate a 3D expression model based on the 3D expression information, and reconstruct the 3D expression model to have a natural facial expression by adding muscle control points to the 3D expression model.
