Noise Removal Algorithm for Polygonal Meshes

In this paper, we present an effective unshrinkage noise removal algorithm to generate smooth geometric models. By introducing the constraints of keeping all triangle barycenters invariant at each smoothing step, the algorithm converts the mesh fairing issue into the minimization of the constrained energy minimization functional, which is then solved efficiently by our iterative method. The experimental results demonstrate that our algorithm can not only quickly remove the noise with good shape preservation, but also be implemented efficiently and robustly.
