Due to the difficulty in generating the effective descriptors which are robust to occlusion and viewpoint changes, place recognition for 3D point cloud remains an open issue. Unlike most of the ...

Global feature-based methods attempt to obtain rigid transformations through an end-to-end framework but often struggle with generalization. In this article, we propose a novel point cloud ...

This repository contains the implementation of AdaptConv for point cloud analysis. Adaptive Graph Convolution (AdaptConv) is a point cloud convolution operator presented in our ICCV2021 paper.
