HeroGS: Hierarchical Guidance for Robust 3D Gaussian Splatting under Sparse Views
HeroGS is a unified framework that enhances robust 3D Gaussian Splatting under sparse-view conditions by employing a hierarchical guidance strategy across image, feature, and parameter levels to regularize Gaussian distributions, refine high-frequency details, and ensure geometric consistency, thereby achieving superior reconstruction fidelity compared to state-of-the-art methods.
