Deformable Surgical Scene Reconstruction with Gaussian Life-Cycle Modeling

EH-SurGS reconstructs deformable surgical scenes from stereo endoscopic video with 3D Gaussian splatting. It assigns each 3D Gaussian a life cycle so irreversible deformations like tissue shearing can be represented, and uses an adaptive motion hierarchy to warp only deformable regions, improving both reconstruction fidelity and rendering speed.

Deformable Gaussian Splatting for Efficient and High-Fidelity Reconstruction of Surgical Scenes

This paper introduces EH-SurGS, a 3D Gaussian splatting method for reconstructing deformable surgical scenes from stereo endoscopic video. 3D Gaussian splatting represents a scene as many anisotropic…
