A pilot study in image enhancement in computed radiography mammogram images using histogram stretching method

Abstract

Efforts on the development of Computer Aided Diagnosis (CADG) system have been extensive. However, locally made CADG systems suitable for Malaysian patients are still unavailable. Many present CADG systems are developed based on Caucasian data. These systems may not be suitable for Malaysian data because the breast tissues of Malaysian women may differ from the Caucasians. This project initiates a study to develop a CADG system suitable for local data. This paper reports the image enhancement stage of 42 computed radiography mammogram images collected from the National Cancer Society of Malaysia. The method of histogram stretching is used to enhance these images which are then evaluated by radiologists based on the BIRADS standardization. © 2008 Springer-Verlag.
