Animating blendshape faces by cross-mapping motion capture data
Animating 3D faces to achieve compelling realism is a challenging task in the entertainment industry. Previously proposed face transfer approaches generally require a high-quality animated source face in order to transfer its motion to new 3D faces. In this work, we present a semi-automatic technique to directly animate popularized 3D blendshape face models by mapping facial motion capture data spaces to 3D blendshape face spaces. After sparse markers on the face of a human subject are captured by motion capture systems while a video camera is simultaneously used to record his/her front face, then we carefully select a few motion capture frames and accompanying video frames as reference mocap-video pairs. Users manually tune blendshape weights to perceptually match the animated blendshape face models with reference facial images (the reference mocap-video pairs) in order to create reference mocapweight pairs. Finally, the Radial Basis Function (RBF) regression technique is used to map...
