Critical Review: Contour Detection and Hierarchical Image Segmentation

Project Review Our project is titled “Image Processing for Video-CT Registration in Sinus Surgery.” We aim to develop an occluding contour extraction algorithm that can reliably and efficiently find edges in sinus surgery endoscopic videos. Our project is a critical component of a larger one that aims to enhance magnetic tracker resolution in sinus surgery. The proposed registration algorithm is being developed by Seth Billings, a graduate student, and it will map the extracted contours to patient CT data in order to enhance registration. We hope that ultimately this enhanced registration will enable an augmented reality overlay to be projected over the endoscopic data so that surgeons can perform faster and better surgeries.
