PUP 3D-GS: Principled Uncertainty Pruning for 3D Gaussian Splatting

TrackGS has been introduced as a novel method that integrates global feature tracks with 3D Gaussian Splatting (3DGS) to enhance COLMAP-free novel view synthesis. This approach addresses the limitations of existing methods that rely on accurate precomputed camera parameters and local constraints, which often fail in complex scenarios.

PEGS, a new framework for reconstructing rigid motion over large spatiotemporal scales, has been introduced, addressing challenges such as severe motion blur and insufficient physical consistency. This framework integrates physical priors with event stream enhancement within a 3D Gaussian Splatting pipeline, enabling effective deblurred modeling and motion recovery.

The introduction of MonoGSDF marks a significant advancement in 3D vision, addressing the challenges of accurate meshing from monocular images.
