Abstract: In this study a one step method is proposed for 2D/3D registration and automatic reconstruction of deformable digestive human organs when making a laparoscopic cholecystectomy in order to build an automatic marker less intraoperative surgical augmented reality system using different image sources such as 2D coloured laparoscopic images or patient specific CT-Scan or MRI data and anatomical knowledge. The method is based on a novel multi-resolution analysis of 2D and 3D scenes using wavelets guided by anatomical trees for reconstruction and surface segmentation of abdominal organs. We take in consideration several laparoscopic standard surgical procedures for enhancing and auto-building of the correspondent deformable 3D model.
