Rh-3DGS: Robust Open-Vocabulary Scene Understanding via Riemannian Huber Distillation and Manifold-Aware Sampling

Xinpeng Zhao, Jiang Jie, Fengyuan Zhang, Lixin Zhan, Dong Wang, Qinyuan Bu +2

ICML 2026poster

Open-vocabulary 3D scene understanding answers free-form text queries over reconstructed scenes. However, lifting dense 2D foundation-model embeddings into 3D Gaussian Splatting (3DGS) is still challenging. Existing 3DGS-based methods often average normalized embeddings in Euclidean space. This igno…

SpecBridge: Spectral Structure Alignment and Transitive Bridging for 3D–2D–Text Pre-Training

Dong Wang, Jie Jiang, Weidong Min, Lixin Zhan, Xinpeng Zhao, Ze Zhang

IJCAI 2026

Open-vocabulary 3D understanding aims to align 3D representations with a unified vision-language semantic space. However, existing methods suffer from the challenge of structural asymmetry caused by sparse observations and holistic geometries. Additionally, the inherent semantic chasm between discre
