We propose an effective semi-supervised method for learning 3D segmentations from a few labeled 3D shapes and a large amount of unlabeled 3D data. For the unlabeled data, we present a novel multilevel consistency loss to enforce consistency of network predictions between perturbed copies of a 3D shape at multiple levels: point level, part level, and hierarchical level. For the labeled data, we develop a simple yet effective part substitution scheme to augment the labeled 3D shapes with more structural variations to enhance training. 2023-03-30T03:53:57Z 2023-03-30T03:53:57Z 2023 Book https://link.springer.com/article/10.1007/s41095-022-0281-9 https://dlib.phenikaa-uni.edu.vn/handle/PNK/7325 en application/pdf Springer
