Abstract: Optical aberration is a ubiquitous degeneration in realistic lens-based imaging systems. Optical aberrations are caused by the differences in the optical path length when light travels ...
Abstract: This letter presents a framework for 3D instance segmentation on point clouds. A 3D convolutional neural network is used as the backbone to generate semantic predictions and instance ...
Most existing point cloud upsampling methods have roughly three steps: feature extraction, feature expansion and 3D coordinate prediction. However, they usually suffer from two critical issues: (1) ...
