摘要 利用反调和平均曲率流,提出一种各向异性、快速的不规则三角网格去噪算法.模型中选择的各向异性演化权函数比较简单,同时保持了网格的几何特征.分别用显式格式和半隐式格式实现了此平滑算法.提供的数值例子显示了模型的有效性. 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 simi-implicit scheme. Finally, we provide a family of examples to demonstrate the quality of our results.
