Point density aware
WebAug 1, 2024 · To better model the spatial distribution of unevenly distributed 3D point sets, a density-aware convolution module is designed by reweighting the weights of convolution kernels using the inversed density of each point. Based on the proposed convolution module, we further build a multi-scale CNN model to achieve point cloud semantic labeling. WebNov 24, 2024 · To tackle these problems, we propose a new similarity measure named Density-aware Chamfer Distance (DCD). It is derived from CD and benefits from several desirable properties: 1) it can detect ...
