The existing works treat different primitive types separately, thus limiting them to finite shape categories. To address this issue, we seek a generalized primitive segmentation on point clouds. Taking inspiration from B\u00e9zier decomposition on NURBS models, we transfer it to guide point cloud segmentation casting off primitive types. A joint optimization framework is proposed to learn B\u00e9zier primitive segmentation and geometric fitting simultaneously on a cascaded architecture. Specifically, we introduce a soft voting regularizer to improve primitive segmentation and propose an auto-weight embedding module to cluster point features, making the network more robust and generic. We also introduce a reconstruction module where we successfully process multiple CAD models with different primitives simultaneously. We conducted extensive experiments on the synthetic ABC dataset and real-scan datasets to validate and compare our approach with different baseline methods. Experiments show superior performance over previous work in terms of segmentation, with a substantially faster inference speed.<\/jats:p>","DOI":"10.24963\/ijcai.2023\/84","type":"proceedings-article","created":{"date-parts":[[2023,8,11]],"date-time":"2023-08-11T08:31:30Z","timestamp":1691742690000},"page":"754-762","source":"Crossref","is-referenced-by-count":4,"title":["BPNet: B\u00e9zier Primitive Segmentation on 3D Point Clouds"],"prefix":"10.24963","author":[{"given":"Rao","family":"Fu","sequence":"first","affiliation":[{"name":"INRIA; Geometry Factory"}]},{"given":"Cheng","family":"Wen","sequence":"additional","affiliation":[{"name":"The University of Sydney"}]},{"given":"Qian","family":"Li","sequence":"additional","affiliation":[{"name":"INRIA"}]},{"given":"Xiao","family":"Xiao","sequence":"additional","affiliation":[{"name":"Shanghai Jiao Tong University"}]},{"given":"Pierre","family":"Alliez","sequence":"additional","affiliation":[{"name":"INRIA"}]}],"member":"10584","event":{"number":"32","sponsor":["International Joint Conferences on Artificial Intelligence Organization (IJCAI)"],"acronym":"IJCAI-2023","name":"Thirty-Second International Joint Conference on Artificial Intelligence {IJCAI-23}","start":{"date-parts":[[2023,8,19]]},"theme":"Artificial Intelligence","location":"Macau, SAR China","end":{"date-parts":[[2023,8,25]]}},"container-title":["Proceedings of the Thirty-Second International Joint Conference on Artificial Intelligence"],"original-title":[],"deposited":{"date-parts":[[2023,8,11]],"date-time":"2023-08-11T08:34:25Z","timestamp":1691742865000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ijcai.org\/proceedings\/2023\/84"}},"subtitle":[],"proceedings-subject":"Artificial Intelligence Research Articles","short-title":[],"issued":{"date-parts":[[2023,8]]},"references-count":0,"URL":"https:\/\/doi.org\/10.24963\/ijcai.2023\/84","relation":{},"subject":[],"published":{"date-parts":[[2023,8]]}}}
