摘要
提出了一个基于双边滤波器的特征保持的自适应三角网格模型光顺算法,该算法为了加强保持特征的效果,结合网格局部顶点一阶邻域的几何特征并将改进后的双边滤波算子应用于顶点的位置更新操作.在光顺过程中有效地避免了三角网格模型的过度光顺现象.给出了几个实验实例来说明该算法在去除网格噪音的同时保留特征的有效性.
A simple and adaptive algorithm is presented in this paper to preserve the feature of the triangular mesh model while the mesh is smoothed. In this algorithm, the bilateral filter is improved to incorporate local first-order properties of the mesh to enhance the effectiveness of the filter in preserving features. The smoothing process is effective to avoid over-smoothing the triangular meshes. Several examples are given to demonstrate the effectiveness of this algorithm in preserving the feature while removing noise from the mesh.
