Abstract
A digital image processing method automatically separates (segments) the desired regions in a digital radiographic image (i.e., the body part being imaged) from the undesired regions (background areas around the body part that have received unattenuated radiation or foreground areas that have received very little radiation due to the use of radiation limiting devices). The method includes the steps of edge detection, block generation, block classification, block refinement and bit map generation.
