论文摘要
我们引入脂肪垫笼子来摆姿势面部网眼。它结合了笼子代表和面部解剖元素，并使没有艺术技能的用户可以快速勾勒出现实的面部表情。该模型依赖于一个或几个笼子，该笼子变形了人脂肪垫映射的网格。我们提出了一个新功能，使用地质距离滤波绿色坐标，以防止全局变形，同时确保边界处的平滑变形。嘴唇，鼻孔和眼睑的处理略有不同，以折叠并打开。笼子会自动创建并适合任何新的未知面部网格。为了验证我们的方法，我们提供了一项用户研究，将脂肪垫笼与常规绿色坐标进行比较。结果表明，脂肪垫笼在复制现有面部表情方面带来了显着改善。
We introduce Fat Pad cages for posing facial meshes. It combines cage representation and facial anatomical elements, and enables users with no artistic skill to quickly sketch realistic facial expressions. The model relies on one or several cage(s) that deform(s) the mesh following the human fat pads map. We propose a new function to filter Green Coordinates using geodesic distances preventing global deformation while ensuring smooth deformations at the borders. Lips, nostrils and eyelids are processed slightly differently to allow folding up and opening. Cages are automatically created and fit any new unknown facial mesh. To validate our approach, we present a user study comparing our Fat Pad cages to regular Green Coordinates. Results show that Fat Pad cages bring a significant improvement in reproducing existing facial expressions.
