Abstract

We present a new surface smoothing method. The method enhances sharp variation points of surface normals and, therefore, is good for stable detection of salient surface creases and natural shape segmentation. The method is based on local weighted averaging (diffusion) of surface normals where weights depend nonlinearly on surface curvatures.
