ABSTRACT
Point models from scanned data invariably contain noise. Most denoising methods concentrate on positional information rather than normals, even though rendered images are affected more strongly by noise in normals than positions. This article proposes a novel method for denoising normals for point models based on the bilateral filter. The method treats the filter as a spatial deformation and updates normals iteratively. The bilateral filter is feature preserving; the extension to normals inherits this trait.
INDEX TERMS
