Improving Sparse-View 3DGS Generalization via Flat Minima Optimization

arXiv:2607.00885v1 Announce Type: cross Abstract: Recent advances in neural rendering have established 3D Gaussian Splatting (3DGS) as a highly efficient representation for novel view synthesis, enabling fast training and real-time rendering with strong fidelity. However, when supervision is limited to sparse input views, 3DGS tends to overfit to the observed images and generalize poorly to unseen viewpoints. We address this challenge from the perspective of flat minima (FM) optimization, which seeks solutions that remain stable under small parameter perturbations. Viewing Gaussian parameters

Why this matters
Why now

The continuous research in neural rendering and 3D reconstruction is pushing for more robust and efficient methods, addressing known limitations like overfitting in sparse data scenarios.

Why it’s important

Improved generalization in 3D reconstruction from limited data is crucial for practical applications in robotics, virtual reality, and content creation, reducing data requirements and computational costs.

What changes

This advancement could lead to more reliable 3D models being generated from fewer images, accelerating development in fields reliant on 3D computer vision and lowering barriers to entry.
