Spherical mask: coarse-to-fine 3D point cloud instance segmentation with spherical representation
Coarse-to-fine 3D instance segmentation methods show weak performances compared to recent Grouping-based, Kernel-based and Transformer-based methods. We argue that this is due to two limitations: 1) Instance size over-estimation by axis-aligned bounding box(AABB) 2) False negative error accumulation...
