Effective Features Extracting Approach Using MFCC for Automated Diagnosis of Alzheimer’s Disease
Abstract
This paper proposes a Computer Aided Diagnosis (CAD) system for extracting the most significant features of Alzheimer’s disease (AD) using the Mel-Scale Frequency Cepstral Coefficients (MFCC). The features extracted from AD MRI images are effective features used for the diagnosis of AD. To test the proposed model, the database used Open Access Series of Imaging Studies (OASIS) database for Magnetic Resonance Imaging (MRI). First, the images are transformed from 3-D to 1-D, then it will be processed using the approach given in [1] for feature reduction. In addition, the MFCC algorithm will be used to extract the effective features, then applying a Linear Support Vector Machine (SVM) classifier for classification step. This paper presents the comparison study between the approach given in [1], the approach using MFCC only, and using proposed approach. The obtained results provides excellent results using the proposed algorithm with high accuracy using small number of significant extracted features.
