Optimal scanning, display, and segmentation of the International Labor Organization (ILO) x-ray images set for pneumoconiosis

Abstract

A method for scanning and displaying chest radiographs (x-rays) is presented. The new method treats scanning independent of display, allowing for maximum information content to be captured during the scanning process, and then for this information to be optimally displayed using a new function for maximizing the contrast variation throughout the image. The quality of the digitized x-ray images were compared against the original x-ray films and were found to be of comparable visualization quality. The rib parenchymal is then segmented by an active shape model.
