SGPN: Similarity Group Proposal Network for 3D Point Cloud Instance Segmentation

CVPR 2018 Weiyue WangRonald YuQiangui HuangUlrich Neumann

We introduce Similarity Group Proposal Network (SGPN), a simple and intuitive deep learning framework for 3D object instance segmentation on point clouds. SGPN uses a single network to predict point grouping proposals and a corresponding semantic class for each proposal, from which we can directly extract instance segmentation results... (read more)
