Classification: CPC G  H | IPC G  H

Claim 5:
6. The method of claim 4, further comprising:
during a second setup period prior to the video call:
accessing a second target image of the second user;
detecting a second target face in the second target image;
representing a second target constellation of facial landmarks, detected in the second target image, in a second target facial landmark container;
generating a second target set of face model coefficients;
generating a second synthetic test image based on the second target facial landmark container, the second target set of face model coefficients, and the synthetic face generator;
characterizing a second difference between the second synthetic test image and the second target face detected in the second target image;
adjusting the second target set of face model coefficients to reduce the second difference; and
generating a second face model, associated with the second user, based on the second target set of face model coefficients;

at the second device during the video call:
accessing a second video feed captured by a second camera, coupled to the second device, during the video call;
extracting a second frame, recorded at a second time, from the second video feed;
detecting a second constellation of facial landmarks in the second frame;
representing the second constellation of facial landmarks in a second facial landmark container; and
transmitting the second constellation of facial landmarks to the first device; and

at the first device during the video call:
loading a local copy of the second face model;
transforming the second facial landmark container and the local copy of the second face model into a second synthetic face image according to the synthetic face generator at the second device; and
displaying the second synthetic face image for the second user at approximately the second time.
