Abstract
A method of detecting and identifying abnormal regions in living tissue depicted in a digital radiograph includes, in each of a number of stages, identifying an abnormal region; and reducing any overlap between the identified regions. Typically the digital radiograph is a mammogram and the abnormal regions are suspicious mass regions in a human breast. Five stages of identifying are used to detect a region with a global minimum in the smoothed image; a region with a local minimum in the original image; a region with a local minimum in the filtered image; a small region of rounded shape and low contrast; and a region of rounded shape and high contrast.
