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…
Edge Approximation Text Detector
Chuang Yang, Xu Han, Tao Han +3
Pursuing efficient text shape representations helps scene text detection models focus on compact foreground regions and optimize the contour reconstruction steps to simplify the wh…
Zoom Text Detector
Chuang. Yang, Mulin. Chen, Yuan. Yuan +1
To pursue comprehensive performance, recent text detectors improve detection speed at the expense of accuracy. They adopt shrink-mask based text representation strategies, which le…
