| 摘 要： | INTRODUCTION With the proliferation of 3D scanning tools, in- terest in removing noise from meshes has increased. An important problem is how to suppress noise while preserving desirable geometric features of the model. In general, smoothing algorithms are roughly classi- fied into two categories: linear and nonlinear smoothing (Gonzalez and Woods, 2002). For linear smoothing, each mesh point is moved to the bary- center of its neighbors. Linear smoothing treats fea- ture (large variatio…

| Abstract: | Motivated by the conception of Lee et al. (2005)’s mesh saliency and Chen (2005)’s contextual discontinuities, a novel adaptive smoothing approach is proposed for
noise removal and feature preservation. Mesh saliency is employed as a multiscale measure to detect contextual discontinuity
for feature preserving and control of the smoothing speed. The proposed method is similar to the bilateral filter method.
Comparative results demonstrate the simplicity and efficiency of the presented method, which makes it an excellent solution
for smoothing 3D noisy meshes.
