Mini-Splatting2: Building 360 Scenes within Minutes via Aggressive Gaussian Densification
Contributions: โข Through a comprehensive analysis of the 3DGS geometry modeling process, we identify the feasibility of extracting dense points from Gaussian representations and their potential for refinement into high-quality Gaussian models.
โข We introduce aggressive Gaussian densification, which increases the number of critical Gaussians to speed up optimization convergence. To further accelerate the process, we propose visibility Gaussian culling, using per-view Gaussian importance as precomputed visibility. โข Extensive experimental results on multiple benchmarks and datasets demonstrate that our Mini-Splatting2 achieves a balanced trade-off among optimization time, number of Gaussians and rendering quality.
