Abstract
A method for identifying a projection view and an orientation of a chest radiograph. The method includes the steps of: providing an input digital image of the chest radiograph; preprocessing the input digital radiographic image; classifying the view of the input digital radiographic image; and determining the orientation of the input digital radiographic image.

A method for identifying an AP/PA (anterior-posterior/posterior-anterior) projection view and an orientation of a chest radiograph, the method comprising the steps of:
- providing an input digital image of the chest radiograph;
- preprocessing the input digital radiographic image;
- searching the preprocessed image for a spine midline and lung centerlines;
- classifying the view of the input digital radiographic image as an AP/PA image based on the detection of a spine midline and lung centerlines;
- and
- determining the orientation of the input digital radiographic image using the detected spine midline and lung centerlines, if it is classified as an AP/PA image.
