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…
Real-Scale Island Area and Coastline Estimation using Only its Place Name or Coordinates
Quanyun Wu, Kyle Gao, Wentao Sun +4
Accurate measurement of island area and coastline length is crucial for coastal zone monitoring and oceanographic analysis. However, traditional measurement and mapping methods usu…
Rapid Forest Fuel Load Estimation via Virtual Remote Sensing and Metric-Scale Feed-Forward 3D Reconstruction
Quanyun Wu, Kyle Gao, Wentao Sun +6
Accurate quantification of forest coverage and combustible biomass (fuel load) is critical for wildfire risk assessment and ecosystem management. However, traditional methods relyi…
BCWildfire: A Long-term Multi-factor Dataset and Deep Learning Benchmark for Boreal Wildfire Risk Prediction
Zhengsen Xu, Sibo Cheng, Lanying Wang +4
Wildfire risk prediction remains a critical yet challenging task due to the complex interactions among fuel conditions, meteorology, topography, and human activity. Despite growing…
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…
