Researchers have developed CleanGS, a novel post-hoc method designed to refine 3D Gaussian Splatting (3DGS) scene reconstructions. This technique effectively removes extraneous off-object structures that become visible when a scene is viewed from new angles, without requiring the retraining of the original 3DGS model. CleanGS utilizes a Pareto-guided approach to select optimal views based on mask reliability, camera baseline, and viewing-direction diversity, then employs a two-of-three voting mechanism during rasterization to retain relevant Gaussian elements. The method demonstrates superior performance in PSNR metrics and significantly reduces processing time and memory usage compared to existing cleanup tools like FlashSplat and GaussianCut. AI
