Robust Global Structure-from-Motion via View Graph Pruning

This work proposes a subgraph-guided view graph pruning framework for robust global SfM that first partition the view graph into locally consistent subgraphs and performs global SfM within each subgraph to obtain reliable camera poses.

Closed-Form Convolution for physically-accurate defocus in Gaussian Splatting

This work presents a rendering pipeline that seamlessly integrates a physically accurate and differentiable depth-of-field model into the 3D Gaussian Splatting (3DGS) rasterization process, and enables high-fidelity 3D reconstruction from blurry, multi-focus image sets, while supporting realistic post-capture effects s...
