1. A method of video conferencing, the method comprising the steps of:

  • detecting a human face of a video conference participant depicted in portions of a video stream;

    creating by explicitly modeling one or more explicit object models to model the face of the video conference participant;

    generating one or more implicit object models relative to parameters obtained from the explicit object models to facilitate creation of a compact encoding of the video conference participant'"'"'s face;

    using the implicit object model, creating a photorealistic avatar representation of the video conference participant;

    periodically checking to determine whether the implicit object model is working optimally; and

    responding to a determination that the implicit object model is not working by processing the step of detecting a human face of a video conference participant and in response to detecting a human face, searching for existing calibration information for the detected human face.
