GR-Gaussian: Graph-Based Radiative Gaussian Splatting for Sparse-View CT Reconstruction
Yikuang Yuluo, Yue Ma, Kuan Shen +4
3D Gaussian Splatting (3DGS) has emerged as a promising approach for CT reconstruction. However, existing methods rely on the average gradient magnitude of points within the view,…
