Paper Abstract

The diagnostic quality of radiographic images can be improved with some basic image processing algorithms. This is shown by a two step procedure on X-ray chest images in this paper. First, a revised adaptive unsharp masking method was applied which sharpens some boundary features and in the meantime smooths some others. After this, an extended Sobel edge detection and region growing process followed which further delineates the suspected lung nodules. The final results give a clearer show of wanted features.
