Calibrated Closed-Form Uncertainty for Radiative Gaussian Splatting in Sparse-View CT
Chulin Zhao, Yiran Xu, Shu Liu
Radiative Gaussian splatting has made sparse-view CT reconstruction fast, but existing methods output point estimates with no notion of where the reconstruction can be trusted. We exploit a property of transmissive X-ray imaging that RGB splatting cannot claim -- projection and v…
