Point Cloud Compr ession (PCC) has also attracted more attention as a primary step before po int cloud transferring and saving, where the geometry compression is an im portant component of PCC to compress the points geometrical structures. Ho wever, existing non-learning-based geometry compression methods are often limited by manually pre-defined compression rules. Though learning-based c ompression methods can significantly improve the algorithm performances by learning compression rules from data, they still have some defects. Voxel -based compression networks introduce precision errors due to the voxelize d operations, while point-based methods may have relatively weak robustnes s and are mainly designed for sparse point clouds. In this work, we propos e a novel learning-based point cloud compression framework named 3D Point Cloud Geometry Quantiation Compression Network (3QNet), which overcomes th e robustness limitation of existing point-based methods and can handle den se points. By learning a codebook including common structural features fro m simple and sparse shapes, 3QNet can efficiently deal with multiple kinds of point clouds. According to experiments on object models, indoor scenes , and outdoor scans, 3QNet can achieve better compression performances tha n many representative methods.\n\nRegistration Category: FULL ACCESS, ON-D EMAND ACCESS\n\nLanguage: ENGLISH\n\nFormat: IN-PERSON, ON-DEMAND URL:https://sa2022.siggraph.org/en/full-program/?id=papers_327&sess=sess15 6 END:VEVENT END:VCALENDAR
