Claim 9:
10. The method of claim 9:
further comprising:
accessing a video clip of the user; and
for each frame in a set of frames in the video clip:
detecting the target face in a secondary region of the frame;
characterizing positions of a secondary set of features, analogous to facial landmark types in the predefined set of facial landmark types, detected in the secondary region of the frame;
representing positions of the secondary set of features in a secondary facial landmark container;
characterizing intensities of actions of a set of muscles, associated with the predefined set of action units, detected in the secondary region of the frame;
representing intensities of actions of the set of muscles in a secondary facial expression container;
defining a secondary set of face model coefficients;
transforming the secondary facial landmark container, the secondary facial expression container, and the secondary set of face model coefficients into a secondary synthetic face image according to the synthetic face generator;
characterizing a secondary difference between the secondary synthetic face image and the secondary region of the frame depicting the face; and
adjusting the secondary set of face model coefficients to reduce the secondary difference; and

wherein generating the first face model comprises calculating the first face model based on a combination of:
the target set of face model coefficients; and
secondary sets of face model coefficients associated with the set of frames.
