Point clouds acquired from scanning devices are often perturbed by noise, which affects downstream tasks such as surface reconstruction and analysis. The distribution of a noisy point cloud can be viewed as the distribution of a set of noise-free samples p(x) convolved with some noise model n, leading to (p * n)(x) whose mode is the underlying clean surface. To denoise a noisy point cloud, we propose to increase the log-likelihood of each point from p * n via gradient ascent—iteratively…

Deep Point Cloud Reconstruction

A deep point cloud reconstruction network consisting of a 3D sparse stacked-hourglass network as for the initial densification and denoising, and a refinement via transformers converting the discrete voxels into 3D points called amplified positional encoding is proposed.

Contrastive Learning for Joint Normal Estimation and Point Cloud Filtering
