Fast denoising of surface meshes with intrinsic texture

We describe a fast, dynamic, multiscale iterative method that is designed to smooth, but not over-smooth, noisy triangle meshes. Our method not only preserves sharp features but also retains visually meaningful fine-scale components or details, referred to as intrinsic texture. An anisotropic Laplacian (AL) operator is first developed. It is then embedded in an iteration that gradually and adaptively increases the importance of data fidelity, yielding a highly efficient multiscale algorithm (MSAL) that is capable of handling both intrinsic texture and mesh-sampling irregularity without any significant cost increase.
