GeoGuide: Hierarchical Geometric Guidance for Open-Vocabulary 3D Semantic Segmentation
CVPR 2026
Open-vocabulary 3D semantic segmentation aims to segment arbitrary categories beyond the training set. Existing methods predominantly rely on distilling knowledge from 2D open-vocabulary models. However, aligning 3D features to the 2D representation space restricts intrinsic 3D geometric learning an
