Paper Title
Automatic Detection of Diabetic Retinopathy using CNN and R-CNN

Abstract
Diabetic Retinopathy (DR) is an eye abnormality caused as a result of long term diabetes. As the disease progresses it leads to distortion and blurred vision. The diagnosis of DR using color fundus image requires skilled clinicians to identify the presence of critical features which makes this a difficult and time consuming task. In our paper we propose a CNN and R-CNN approach to diagnose DR from digital fundus images. In our method we have used 9 layers for CNN classification, trained it on 180 fundus images and tested on 250 images. All the images were classified into two groups i.e., with DR and without DR. The accuracy of CNN was found to be 86%. In our second phase we implemented a new approach were the whole image was segmented and only the regions of interest were taken for further processing. This R-CNN (Regional CNN) approach was found to be more efficient in terms of speed and accuracy. An accuracy of approximately 92% was obtained from R-CNN.
