             abstract = "In recent years, surface denoising has been a subject of intensive 
                         research in geometry processing. Most of the recent approaches for 
                         mesh denoising use a two-step scheme: normal filtering followed by 
                         a point updating step to match the corrected normals. In this 
                         paper we propose an adaptation of such two-step approaches for 
                         point-based surfaces, exploring three different weighting schemes 
                         for filtering normals. Moreover, we also investigate three 
                         techniques for normal estimation, analyzing the impact of each 
                         normal estimation method in the whole point-set smoothing process. 
                         Towards a quantitative analysis, in addition to conventional 
                         visual comparison, we evaluate the effectiveness of different 
                         choices of implementation using two measures, comparing our 
                         results against state-of-art point-based denoising techniques.",
