Adaptive mesh smoothing for feature preservation

Abstract

A simple algorithm is presented in this paper to preserve the feature of the mesh while the mesh is smoothed. In this algorithm, the bilateral filter is modified to incorporate local first-order properties of the mesh to enhance the effectiveness of the filter in preserving features. The smoothing process is error-bounded to avoid over-smoothing the mesh. Several examples are given to demonstrate the effectiveness of this algorithm in preserving the feature while removing noise from the mesh. © Springer-Verlag Berlin Heidelberg 2005.
