TL;DR
Results suggest that decoupled matching improves robustness to appearance-driven confusion in indoor point-cloud segmentation and propose D2M-Net, a decoupled dual-matching network that separates backbone features into geometry-oriented and semantic-oriented subspaces before prototype comparison.
A comprehensive geometric-semantic fusion mechanism that resolves geometric noise and semantic ambiguity by explicitly utilizing semantic guidance and formulating 3D segmentation as solving point-and-set merging and partitioning problems, and an innovative manifold-distance-based point cloud refinement strategy.
This work proposes a segmentation framework guided by Contrastive Language–Image Pre-training (CLIP) that enriches sparse 3D tokens with vision–language semantic priors and introduces a decoupled CLIP-induced semantic residual that forms semantic-geometric attention biases for local window attention.
DLPANet is proposed, a novel dual-level prototype alignment network centered on Prototype-Guided Spatial Attention, enabling simultaneous modeling of scene context and fine-grained details and demonstrates that the decoupled dual cross-attention mechanism provides superior prototype-query alignment compared to prior gl...
Results from an adaptation of DINOv3 to the instance-level fusion pipeline of IIFNet3D are interpreted as evidence for a controlled transfer recipe rather than as a causal estimate of the individual contributions of VAID or depth filtering.
UniQuery4R is presented, a query-conditioned framework that encodes a multi-frame clip once and selects the source view, target view, and continuous source-image coordinate only at decoding time via source-to-target cross-attention, and introduces a direction-magnitude parameterization of scene flow with separate super...
Unified 3D vision-language systems must combine complementary geometry, scale, and appearance cues while supporting tasks from instance segmentation to language-guided reasoning. Existing methods often process point clouds, voxel grids, and multi-view images independently; directly combining these heterogeneous represe...
