Towards Uniform Point Distribution in Feature-preserving Point Cloud Filtering. (arXiv:2201.01503v1 [cs.CV])

As a popular representation of 3D data, point cloud may contain noise and
need to be filtered before use. Existing point cloud filtering methods either
cannot preserve sharp features or result in uneven point distribution in the
filtered output. To address this problem, this paper introduces a point cloud
filtering method that considers both point distribution and feature
preservation during filtering. The key idea is to incorporate a repulsion term
with a data term in energy minimization. The repulsion term …
