Compact 3D Gaussian Representation for Radiance Field

Figure 1. Our method achieves reduced storage and faster rendering speed while maintaining high-quality reconstruction of 3DGS [18]. The core idea is to effectively remove the redundant Gaussians that do not significantly contribute to the overall performance (the sparser distribution of Gaussian points and reduced ellipsoid redundancy shown in the figure). We also introduce a more compact representation of Gaussian attributes, resulting in markedly improved storage efficiency and rendering speed.
