Mesh Smoothing via Mean and Median Filtering Applied to Face Normals

In this paper, we introduce iterative mean and median filtering schemes for smoothing noisy 3D shapes given as triangle meshes. Our main idea consists of applying mean and median filtering schemes to mesh normals and then update the mesh vertex position in order to fit the mesh to the modified normals. We also give a quantitative evaluation of the proposed mesh filtering schemes and compare them with conventional mesh smoothing procedures such as the Laplacian smoothing flow and the mean curvature flow. We demonstrate that our mean and median mesh filtering methods outperform the conventional Laplacian and mean curvature flows in terms of accuracy and resistance to oversmoothing.
