ExtraGS: Enhancing Endoscopic View Extrapolation via Diffusion-Guided 3D Gaussian Splatting
Cheng-Tai Hsieh, Jiwei Shan, Han Fang +6
The paper introduces ExtraGS, a method that improves extrapolation of endoscopic video views by combining uncertainty‑driven virtual camera sampling with diffusion‑guided refinemen…
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…
Information-Theoretic Geometry Optimization and Physics-Aware Learning for Calibration-Free Magnetic Localization
Wenxuan Xie, Yuelin Zhang, Qingpeng Ding +4
Wireless localization of permanent magnets enables occlusion-free guidance for medical interventions, yet its practical accuracy is fundamentally limited by two coupled challenges:…
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…
4D Monocular Surgical Reconstruction under Arbitrary Camera Motions
Jiwei Shan, Zeyu Cai, Cheng-Tai Hsieh +5
Reconstructing deformable surgical scenes from endoscopic videos is challenging and clinically important. Recent state-of-the-art methods based on implicit neural representations o…
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…
