PathNet: Path-Selective Point Cloud Denoising

Wei, Zeyong (author), Chen, Honghua (author), Nan, L. (author), Wang, Jun (author), Qin, Jing (author), Wei, Mingqiang (author)

Current point cloud denoising (PCD) models optimize single networks, trying to make their parameters adaptive to each point in a large pool of point clouds. Such a denoising network paradigm neglects that different points are often corrupted by different levels of noise and they may convey different geometric structures. Thus, the intricacy of...
