Paper Abstract

The performance of four methods for feature enhanced mammographic images—optimal adaptive neighborhood imaging, automatic spatial filtering, adaptive histogram equalization imal contrast pixel to pixel—are compared. Each method is te a database of 50 mammographic images, which included similar shaped nodules. A contrast parameter was used to compare the performance of each processing method. It was found that the ma trast pixel-to-pixel method gives the highest contrast value. A mamogram including a real subtle lesion is used to illustrate the use of this last contrast enhancement method in clinical diagnosis.
