Facial Animation Remapping Based on Spherical Parameterization
基于球面参数化的人脸动画重映射

Animation remapping is an important way to produce realistic facial animation. We introduce spherical parameterization to prevent overlap and utilize barycentric coordinate as the interpolation weight of motion vectors, which achieves fast remapping of realistic animation and requires fewer key points. Combined with automatic division of lip contact line and lip region division, it can correct errors of the mouth animation. The method is applicable to real-time facial animation remapping for sparse markers in Motion Capture.
