Abstract

This paper describes a solution to the problem of transmitting “talking head” video in real-time across low-bandwidth transmission media. Our solution is based on a video reconstruction system, which can generate realistic audio-visual narrations from arbitrary pieces of text. The system uses standard synthetic speech techniques to create an audio track and then produces a synchronized “talking head” using full-frame morphing of real-world facial images (key-frames). We discuss issues of original data capture, transmission protocols, synchronization, interpolation, and the modeling of various physical activities which are vital to maintaining the “plausibility” of the final synthetic video sequence.
