Assessment of combined textural and morphological features for diagnosis of breast masses in ultrasound

Abstract: The objective of this study is to assess the combined performance of textural and morphological features for the detection and diagnosis of breast masses in ultrasound images We have extracted a total of forty four features using textural and morphological techniques Support vector machine (SVM) classifier is used to discriminate the tumors into benign or malignant The performance of individual as well as combined features are assessed using accuracy(Ac), sensitivity(Se), specificity(Sp), Matthews correlation coefficient(MCC) and area AZ under receiver operating characteristics curve The individual features produced classification accuracy in the range of 6166% and 9083% and when features from each category are combined, the accuracy is improved in the range of 7916% and 9583% Moreover, the combination of gray level co-occurrence matrix (GLCM) and ratio of perimeters (P ratio ) presented highest performance among all feature combinations (Ac 9585%, Se 96%, Sp 9146%, MCC 09146 and AZ 09444)The results indicated that the discrimination performance of a computer aided breast cancer diagnosis system increases when textural and morphological features are combined
