A feature-based approach to facial expression cloning method

摘要

The present invention relates to a method for duplicating facial expression animation based on a virtual character region, and more particularly, to a technique for generating complex and various facial expression animations in real time with only a few example models by recycling existing animation data.;According to the present invention, there is provided a method for replicating a facial expression animation based on a virtual character region, comprising: a first step of analyzing a facial expression of a given original example model; A second step of duplicating the original example model every frame by mixing the target example models when an input face animation of the target example model and the corresponding target example model is given; And a third step of synthesizing the duplicated original example model into a facial expression animation in real time.;Therefore, the present invention can be effectively used in the fields of three-dimensional games, help desks of help desks, avatars in chat rooms, movies, advertisements, etc., which must generate realistic facial expressions in a short time.;Virtual Characters, Example Models, Animation, Region Based, Facial Expressions
