Abstract
A system and method for automatically detecting anatomical landmarks in a radiographic image, preferably for total hip replacement applications, in accordance with the present invention, provides a region of interest of the image, and determines a first landmark in the region of interest by computing an intensity ridge map. A second landmark is determined in the region of interest based on a position and orientation of the first landmark, and measurements are performed on the image based on positions of the first and second landmarks.
