By overlaying preoperative radiological 3-D models onto the intraoperative laparoscopic video, augmented-reality (AR) displays promise to increase surgeons’ visual awareness of high-risk surgical targets (e.g., the location of a tumor). Existing AR surgical systems lack in robustness and accuracy because of the many challenges in endoscopic imagery, such as frequent changes in illumination, rapid...
We present our novel Adaptive Multi-Affine (AMA) feature-matching algorithm that finds correspondences between two views of the same non-planar object. The proposed method only uses monocular images to robustly match clusters of 2-D features according to their relative position on the object surface; finally, AMA adaptively finds the best number of clusters that maximizes the number of matching features...
