A graph total variation regularizer on surface normals, optimized with ADMM on a bipartite graph, upsamples 3D point clouds with lower point-to-point and point-to-plane errors than APSS and RIMLS.
The weight definition in (2) is similar to bilateral filter weights defined in [23] with domain and range filters

3D Point Cloud Super-Resolution via Graph Total Variation on Surface Normals
A graph total variation regularizer on surface normals, optimized with ADMM on a bipartite graph, upsamples 3D point clouds with lower point-to-point and point-to-plane errors than APSS and RIMLS.
