Mesh Simplification Based on Facial Features Region Partition

摘要：

This paper proposes a mesh simplification method based on facial features region partition for the special three-dimensional facial mesh model. According to distribution of feature points, the face is divided into several parts consisting of critical feature regional and non-critical feature regional. This method adjusts different areas using different curvature values. This algorithm also uses edge collapse method to reduce the density of meshes. As curvature is useful to enhance the shape description, the high details of key feature area are kept while other areas are simplified.
