Feature-Preserving Denoising of Irregular Mesh Using Inverse Harmonic Mean Curvature Flow

Based on the inverse harmonic mean curvature flow,an anisotropic approach is presented to rapidly remove undesirable noise from irregularly triangulated data while retaining desirable geometric feature ,and the anisotropic diffusion weighting function in our model is simple.We implement the fairing diffusion process with both a simple explicit scheme and a sim-i implicit scheme.Finally,we provide a family of examples to demonstrate the quality of our results.
