FrontierGS: Progressive View-Space Frontier Expansion for Sparse 3D Gaussian Splatting
FrontierGS expands sparse 3D Gaussian Splatting by dynamically generating and promoting student views around existing teacher views. It uses a curriculum-guided strategy to progressively introduce more diverse viewpoints, ensuring that only high-quality, geometrically consistent pseudo-views are added to the training set. This mitigates the problem of insufficient supervision in sparse view settings.
