Evidencepartial
To address this issue, we propose graph-based spatial distribution optimization for compact 3D Gaussian Splatting (GS^2), which enhances reconstruction quality by optimizing the spatial distribution of Gaussian points.
Implicationpartial
Directly stated as the core objective of the method in the abstract.
Verificationpartial

Evidencepartial
Many pruning-based 3DGS variants have been proposed for memory saving, but often compromise spatial consistency and may lead to rendering artifacts.
Implicationpartial
Stated as a motivation for the work, but is a general claim about existing methods rather than a direct result from this paper's experiments.
Verificationpartial

Evidencepartial
Nevertheless, its practicality is constrained by the high memory cost due to a huge number of Gaussian points.
Implicationpartial
Stated as a well-established problem in the field that motivates the work.
