Abstract
In this paper, a comparative analysis of different texture features based on local operator has been produced for the determination of mammographic masses as benign or malignant. Local Binary Pattern (LBP), LBP Variance (LBPV), and Completed LBP (CLBP) descriptors are extracted to evaluate their potential for mass classification in a Computer-Aided Diagnosis (CAD) system. An Az value of 0.97 ± 0.02 and an accuracy of 92.25 ± 0.01% have been achieved, while experimenting on 200 mass cases from the DDSM database, by selecting the optimal set of features employing stepwise logistic regression method, followed by classification via Fisher Linear Discriminant Analysis (FLDA) using 10-fold cross validation.
