Agentic Building-Aware Satellite Gaussian Splatting for Auditable Urban DSM Reconstruction
Wentao Sun, Zhengsen Xu, Yiping Chen +2
Urban-scale 3D reconstruction from satellite imagery supports disaster response, city monitoring, and geospatial digital twins, yet neural rendering methods typically optimize aver…
Lift, Associate, and Fuse: A Decision-Centric Framework for 2D-to-3D Foundation Model Transfer
Wentao Sun, Yiping Chen, John S. Zelek +1
Methods that transfer predictions from two-dimensional foundation models into three-dimensional segmentation are commonly grouped by task or representation. Those groupings obscure…
CDSeg: A Renderable Gaussian Carrier for Image-to-3D Label Transfer
Wentao Sun, Yiping Chen, Zhengsen Xu +2
Modern image models provide strong cues about \emph{what} should be segmented in each view, but their masks do not by themselves determine \emph{where} those labels should persist…
SAGOnline: Segment Any Gaussians Online
Wentao Sun, Quanyun Wu, Hanqing Xu +7
3D Gaussian Splatting has emerged as a powerful paradigm for explicit 3D scene representation, yet achieving efficient and consistent 3D segmentation remains challenging. Existing…
PointGauss: Point Cloud-Guided Multi-Object Segmentation for Gaussian Splatting
Wentao Sun, Yiping Chen, John S. Zelek +1
While 3D Gaussian Splatting (3DGS) has established new standards for high-fidelity 3D scene modeling, interpreting massive, unstructured Gaussian primitives into meaningful geospat…
