Skyfall-GS

It reconstructs rough geometry using 3D Gaussian Splatting, then leverages pre-trained text-to-image diffusion models to progressively fill in occluded regions (building facades, etc.) through curriculum-based iterative refinement. Without additional 3D data or street-view images, it significantly improves geometric accuracy, texture realism, and view consistency, outperforming existing methods like Sat-NeRF, CityDreamer, and GaussianCity in both quantitative and qualitative evaluations, while enabling real-time exploration.
