Completing Partial Point Clouds with Outliers by Collaborative Completion and Segmentation

CoRR, 2022
Most existing point cloud completion methods are only applicable to partial point clouds without any noises and outliers, which does not always hold in practice. We propose in this paper an end-to-end network, named CS-Net, to complete the point clouds contaminated by noises or containing outliers. In our CS-Net, the completion and segmentation modules

Point cloud completion via structured feature maps using a feedback network

Computational Visual Media, 2022
In this paper, we tackle the challenging problem of point cloud completion from the perspective of feature learning. Our key observation is that to recover the underlying structures as well as surface details, given partial input, a fundamental component

View-Agnostic Point Cloud Generation for Occlusion Reduction in Aerial Lidar

Remote Sensing, 2022
Occlusions are one of the leading causes of data degradation in lidar. The presence of occlusions reduces the overall aesthetic quality of a point cloud, creating a signature that is specific to that viewpoint and sensor modality.

Dual feature fusion network: A dual feature fusion network for point cloud completion

IET Computer Vision, 2022
Point cloud data in the real world is often affected by occlusion and light reflection, leading to incompleteness of the data. Large‐region missing point clouds will cause great deviations in downstream tasks.
