Abstract
As of today, fine-grained editing of facial performances in movie and video production requires either retouching every single frame or creating a highly detailed CGI model of the actor, both of which is restricted to high-budget productions. In this paper, we present an example-based approach for facial performance editing that achieves realistic results with standard equipment and very little manual intervention. Based on a model-free surface tracking approach, temporally consistent dynamic texture sequences are extracted from multiple video streams. Using such geometry-plus-texture sequences allows transferring facial expressions/performances between videos, which enables the editor, for example, to change the facial expression while leaving the rest of the video untouched. Moreover, concatenating and/or looping these sequences in a motion-graph-like manner offers a convenient way of composing novel facial performances from multiple source videos. Finally, we present a blending method to seamlessly concatenate texture/mesh sequences and to insert a composed facial performance in a target video.
