Claim 10:
11. The method of claim 7:
further comprising:
accessing a video clip of the first user; and
for each frame in a set of frames in the video clip:
detecting the face of the first user in a secondary region of the frame;
characterizing positions of a secondary set of features, analogous to facial feature types in the predefined set of facial feature types, detected in the secondary region of the frame;
representing positions of the secondary set of features in a secondary facial feature container;
defining a secondary set of face model coefficients;
generating a secondary synthetic test image based on the secondary target facial feature container, the secondary target set of face model coefficients, and the synthetic face generator;
characterizing a secondary difference between the secondary synthetic test 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:
the target set of face model coefficients; and
secondary sets of face model coefficients associated with the set of frames.
