3D Gaussian Splatting with Grouped Uncertainty for Unconstrained Images

Hao-Yu Hou, Chia-Chi Hsu, Yu-Chen Huang, Mu-Yi Shen et autres

3D Gaussian Splatting (3DGS) [1] is a promising method for 3D reconstruction and novel view synthesis. However, training it with unconstrained images presents challenges due to transient objects that cause undesired floaters and ghosting artifacts. Although related works using Neural Radiance Fields …
