PR-ENDO: Physically Based Relightable Gaussian Splatting for Endoscopy
Abstract Endoluminal endoscopic imaging—used in diagnosing colorectal cancer and other internal diseases—stands to benefit greatly from accurate 3D reconstructions and novel-view synthesis. However, current methods struggle with artifacts due to constrained camera trajectories and lighting effects that depend heavily on view, often overfitting and failing when viewing from novel angles.
