Summary

3D Gaussian Splatting has revolutionized neural rendering, but its reliance on textured surfaces from SfM techniques can lead to quality issues. The new method GaussianPro aims to address these optimizations challenges by applying a progressive propagation strategy for the densification of 3D Gaussians. The technique leverages geometry priors and patch matching for accurate placement, surpassing traditional 3DGS in quality assessments on the Waymo dataset.

• Revolutionary neural rendering through 3D Gaussian Splatting (3DGS).
• Dependency on surfaces with texture can impede rendering quality in large-scale scenes.
• Progressive propagation strategy introduced with GaussianPro for densification.
• Utilizes existing geometries and patch matching for accurate Gaussian placement.
• Significant quality improvement over standard 3DGS methods as per Waymo dataset analysis.

This paper presents a major leap in the quality of neural renderings, especially for large-scale scenes that often pose challenges due to texture-less surfaces. GaussianPro’s utilization of geometric priors offers a more robust approach to densification, which is crucial for improving the overall rendering quality. It opens avenues for research in scaling neural rendering techniques to various real-world applications, like virtual reality and digital twinning.
