TopoGS: Topology-Aware Anchor Feature Aggregation for Large-Scale 3D Gaussian Splatting
Wei Zhang, Shiqiang Gong, Shengkai Yu +4
Octree-based 3D Gaussian Splatting organizes anchors into multi-level hierarchies for level-of-detail rendering, but features at different levels are typically optimized independen…
VGGT-Align: Bridging Local Reconstruction and Global Consistency for Long-Sequence 3D Reconstruction
Wei Zhang, Yihang Wu, Songhua Li +1
Maintaining global geometric consistency is a central challenge in long-sequence 3D reconstruction, with scale drift being the most critical failure mode. In chunk-based inference…
HiCo-GS: Hierarchical Context Aggregation and Geometric Consistency for Octree Gaussian Splatting
Wei Zhang, Shengkai Yu, Shiqiang Gong +3
Octree-based anchor Gaussian Splatting has emerged as a scalable representation for city-scale novel view synthesis, where multi-level anchors adaptively capture scene content from…
A Large-Scale Dataset and a New Method for RemoteSensing Traffic Object Segmentation
Zhigang Yang, Huiguang Yao, Linmao Tian +2
Remote sensing imagery plays a crucial role in evaluating regional transportation capacity. However, existing segmentation datasets often lack diversity in object categories and sc…
VGGT-CD: Training-Free Robust Registration for 3D Change Detection
Wei Zhang, Songhua Li, Yihang Wu +2
3D change detection from multi-view images is essential for urban monitoring, disaster assessment, and autonomous driving. However, existing methods predominantly operate in the 2D…
