H2G: Hierarchy-Aware Hyperbolic Grouping for 3D Scenes
arXiv CS.CV
•
ArXi:2605.11967v1 Announce Type: new Hierarchical 3D grouping aims to recover scene groups across multiple granularities, from fine object parts to complete objects, without relying on semantic labels or a fixed vocabulary. The main challenge is to transform 2D foundation-model cues into coherent hierarchy supervision and embed that hierarchy in a 3D representation. We propose H2G, a hyperbolic affinity field for hierarchical 3D grouping.
