Non-human-like Characters' Facial Animation Driven by One or Two Actors

摘要

We present a novel system that can transfer facial expressions from an actor to a non-human-like character. Compared with a lot of previous studies, our system requires no special light conditions or facial markers for actors' performance. More significantly, our work can find vertex correspondences between the human face and characters with dissimilar facial structures by creating local-coordinate systems on the character. Experiments show that in our system not only one actor's performance is accurately transferred to non-human-like characters but also two actors' expressions can be simultaneously retargeted to one non-human-like character. Through our approach, virtual characters can have much more vivid expressions.
