In this paper, a 3-class classification system is proposed to classify the breast masses in mammogram images into benign, malignant and normal. The proposed algorithm consists of five modules: pre-processing of images, segmentation of Region of Interest (RoI), feature extraction, feature selection and classification. Pre-processing of an image is done by using Adaptive Histogram Equalization (AHE). Region growing algorithm is used to segment the Region of Interest (ROI) from the pre-processed image. Feature matrix is generated by using Gray Level Co-occurrence Matrix (GLCM) for the segmented ROI. A Genetic algorithm (GA) is used for selecting an optimal set of features from the feature matrix. The performance of GA is compared with a t-test. To evaluate the performance, three classifiers are used and the results are compared. They are multiSVM, KNN, and Naive Bayes classifiers. Totally, six combinations are evaluated. GA+multiSVM, GA+KNN, GA+Naive Bayes, t-test+multiSVM, t-test+KNN, and t-test+Naive Bayes. It is observed that GA+KNN combination outperforms with respect to accuracy. The mammogram images used in this work are collected from the publicly available dataset, Digital Database for Screening Mammography (DDSM).
