我们提出了一个逼真的面部动画系统,该系统基于面部动作编码系统将面部运动捕捉数据分解为具有语义意义的运动通道。基于运动捕获和3D扫描数据之间的语义对应,将捕获的表演重定向到可变形的3D面部模型上。由此产生的面部动画揭示了一个高层次的现实主义相结合的高空间分辨率的三维扫描仪与运动捕捉数据的高时间精度,占微妙的面部运动与稀疏measurements.Such动画系统,使我们能够系统地研究人类的感知移动的面孔。它提供了对动态面部外观的许多方面的控制,同时利用尽可能多的测量数据来避免艺术偏见。使用我们的动画系统,我们报告的实验结果,调查面部运动的偏好任务中的感知自然。对于具有少量头部运动的表情,我们发现基于部分的生成动画系统比基于示例的方法更有益,该方法可以一次变形整个面部。
We present a system for realistic facial animation that decomposes facial motion capture data into semantically meaningful motion channels based on the Facial Action Coding System. A captured performance is retargeted onto a morphable 3D face model based on a semantic correspondence between motion capture and 3D scan data. The resulting facial animation reveals a high level of realism by combining the high spatial resolution of a 3D scanner with the high temporal accuracy of motion capture data that accounts for subtle facial movements with sparse measurements.Such an animation system allows us to systematically investigate human perception of moving faces. It offers control over many aspects of the appearance of a dynamic face, while utilizing as much measured data as possible to avoid artistic biases. Using our animation system, we report results of an experiment that investigates the perceived naturalness of facial motion in a preference task. For expressions with small amounts of head motion, we find a benefit for our part-based generative animation system over an example-based approach that deforms the whole face at once.
