STAR: A Spatial-Topology Aware Routing Framework for Generalizable 3D Scene Understanding
Mingwei Xing, Xinliang Wang, Yifeng Shi
Constructing a unified 3D scene understanding model has long been hindered by the topological discrepancies across sensor modalities. While applying the Mixture-of-Experts (MoE) ar…
AdaptSplat: Adapting Vision Foundation Models for Feed-Forward 3D Gaussian Splatting
Mingwei Xing, Xinliang Wang, Yifeng Shi
This work explores a simple yet powerful lightweight adapter design for feed-forward 3D Gaussian Splatting (3DGS). Existing methods typically apply complex, architecture-specific d…
DoReMi: Bridging 3D Domains via Topology-Aware Domain-Representation Mixture of Experts
Mingwei Xing, Xinliang Wang, Yifeng Shi
Constructing a unified 3D scene understanding model has long been hindered by the significant topological discrepancies across different sensor modalities. While applying the Mixtu…
Fusion-then-Distillation: Toward Cross-modal Positive Distillation for Domain Adaptive 3D Semantic Segmentation
Yao Wu, Mingwei Xing, Yachao Zhang +2
In cross-modal unsupervised domain adaptation, a model trained on source-domain data (e.g., synthetic) is adapted to target-domain data (e.g., real-world) without access to target…
