Amandeep Kaur, Chandan Singh . Cephalometric X-Ray Registration using Angular Radial Transform. International Conference on Recent Advances and Future Trends in Information Technology (iRAFIT 2012). IRAFIT, 9 (April 2012), 18-22.
In this paper we propose a new cephalometric x-ray registration technique based on angular radial transform (ART). The registration is used as a first step in most hybrid cephalometric landmark detection algorithms to find the approximate landmark locations which are further used to find the exact landmark locations in the test x-ray image. All the existing cephalometric algorithms use features like distance between landmarks, distance between landmarks and their centre of gravity and their angular information for x-ray registration. The results achieved by the proposed technique are significantly better in terms of error and robustness.
