LeanGaussian: Breaking Pixel or Point Cloud Correspondence in Modeling 3D Gaussians

CVPR 2025poster

Rencently, Gaussian splatting has demonstrated significant success in novel view synthesis. Current methods often regress Gaussians with pixel or point cloud correspondence, linking each Gaussian with a pixel or a 3D point. This leads to the redundancy of Gaussians being used to overfit the correspo…
