Enhancement of Mammogram Image by using Image Processing Technique

Abstract

This study was carried out in order to enhance the quality of mammography image using image processing technique. The technique of processing image performed using IDL software as platform. The images were collected from a different Centers from 40 females patients. The intensity improvement was measure in low and high intensity areas before and after the enhancement. The result showed that there is an increased in the amount intensity after enhancement for low intensity area was 39.7±21.6 and after enhancement was 63.8±28.2 and for high intensity area before enhancement was 161.6±27.5 and after enhancement was 200.6±23.8. The noise which is represented by standard deviation it shows slight increases after enhancement which record 2.3±1.0 and 4.1±2.1 respectively in the low intensity region. Similar results achived in the high intesity region after enhancement 4.0±2.7 and 7.0±7.6 respectively. The signal of the image also increased after enhancement in the low intensity regions in average from 1429.5±776.7 to 2297.3±1016.2 and for the high intensity regions inaverage from 5816.1±989.5 to 7222.8±855.1. the signal to nosie also arbitrary increased after enhacement in low and high intensity regions from 736.6±536.5 to 697.7±455.7 and from 1978.1±997.5 to 2964.1±3108.7 respetively.
