ABSTRACT:
A method of processing a digital radiographic image includes the following the steps. (1) A digital radiographic image having a radiation region and a collimation region defined by collimation blades at least partially bounding the radiation region is provided. (2) Pixels of the digital radiographic image are detected and classified as collimation boundary transition pixels. (3) Candidate collimation blades are detected and classified from the collimation boundary transition pixels. (4) At a regional level, the collimation region are determined from the results of the line-level delineating step.
