SPNet: segmentation-to-poly network for building footprint extraction

Building extraction from remote sensing images is a core task in urban planning and related applications. However, achieving high-precision building footprint extraction remains challenging due to complex building shapes and background noise. Existing mask-based methods produce r...

Learning instance-level semantic Gaussian representations for occlusion-aware urban scene reconstruction from UAV imagery

UAV-based earth observation provides an efficient and flexible means for detailed urban geospatial modeling and digital twin construction. However, in complex urban environments, foreground occlusions caused by trees, vegetation, and other clutter frequently lead to incomplete st...
