Mini-Splatting: Representing Scenes with a Constrained Number of
  Gaussians
Guangchi Fang Bing Wang
In this study, we explore the challenge of efficiently representing scenes
with a constrained number of Gaussians. Our analysis shifts from traditional
graphics and 2D computer vision to the perspective of point clouds,
highlighting the inefficient spatial distribution of Gaussian representation as
a key limitation in model performance. To address this, we introduce strategies
for densification including blur split and depth reinitialization, and
simplification through Gaussian binarization and sampling. These techniques
reorganize the spatial positions of the Gaussians, resulting in significant
improvements across various datasets and benchmarks in terms of rendering
quality, resource consumption, and storage compression. Our proposed
Mini-Splatting method integrates seamlessly with the original rasterization
pipeline, providing a strong baseline for future research in
Gaussian-Splatting-based works.
