Depth Augmented and FE Free 3D/2D Liver Registration for Laparoscopic Liver AR
arXiv CS.CV

ArXi:2602.17517v2 Announce Type: replace Augmented reality (AR) guidance in laparoscopic liver surgery requires accurate registration of preoperative 3D models to intraoperative 2D video, but remains challenging due to partial visibility, specularities, and tissue deformation. Existing methods often rely on contour-based rigid initialization and finite-element (FE) models for deformable registration, increasing modeling and engineering complexity.
