Abstract

A feature-preserving smoothing algorithm for irregularly sampled meshes is presented in this paper. Low-pass bilateral filter is employed in this algorithm. The parameters of the filter are assigned adaptively for each vertex. Local first-order properties are also incorporated into the filter to further preserve the sharp features of the mesh. A similar technique is also used for polygon smoothing. Several examples are given to graphically and numerically demonstrate the quality of our results.
