ExtraGS: Enhancing Endoscopic View Extrapolation via Diffusion-Guided 3D Gaussian Splatting
Cheng-Tai Hsieh, Jiwei Shan, Han Fang +6
Robot-assisted minimally invasive surgery (MIS) critically depends on reliable endoscopic perception for navigation and safety. However, conventional endoscopes provide only a limi…
DreamReg: Belief-Driven World Model for 2D-3D Ultrasound Registration
Luoyao Kang, Yuelin Zhang, Jiwei Shan +3
Ultrasound (US) is widely used for surgical navigation, yet real-time registration between intraoperative 2D slices and preoperative 3D volumes remains challenging due to partial o…
Leveraging Geometric Prior Uncertainty and Complementary Constraints for High-Fidelity Neural Indoor Surface Reconstruction
Qiyu Feng, Jiwei Shan, Shing Shin Cheng +1
Neural implicit surface reconstruction with signed distance function has made significant progress, but recovering fine details such as thin structures and complex geometries remai…
NRGS-SLAM: Monocular Non-Rigid SLAM for Endoscopy via Deformation-Aware 3D Gaussian Splatting
Jiwei Shan, Zeyu Cai, Yirui Li +5
Visual simultaneous localization and mapping (V-SLAM) is a fundamental capability for autonomous perception and navigation. However, endoscopic scenes violate the rigidity assumpti…
Deformable Gaussian Splatting for Efficient and High-Fidelity Reconstruction of Surgical Scenes
Jiwei Shan, Zeyu Cai, Cheng-Tai Hsieh +2
Efficient and high-fidelity reconstruction of deformable surgical scenes is a critical yet challenging task. Building on recent advancements in 3D Gaussian splatting, current metho…
