A deep convolutional neural network based computer aided diagnosis system for the prediction of Alzheimer's disease in MRI images

•A CAD system is proposed to detect and classify Alzheimer Disease on MRI real image.•Uses MRI differentiation method to differentiate the tumor from the non-tumor cells.•Image preprocessing is performed using 2D-ABF and AHA algorithms.•Image segmentation is done to retrieve ROI using MEM algorithm.•Features are retrieved using GLCM and DCNN is to classify normal and abnormal image.
