Semantic Segmentation-Assisted Instance Feature Fusion for Multi-Level 3D Part Instance Segmentation. (arXiv:2208.04766v1 [cs.CV])

Recognizing 3D part instances from a 3D point cloud is crucial for 3D
structure and scene understanding. Several learning-based approaches use
semantic segmentation and instance center prediction as training tasks and fail
to further exploit the inherent relationship between shape semantics and part
instances. In this paper, we present a new method for 3D part instance
segmentation. Our method exploits semantic segmentation to fuse nonlocal
instance features, such as center prediction, and further enhances the fusion
scheme in a multi- …
