Automated Smartphone Based System for Diagnosis of Diabetic Retinopathy

Early diagnosis of diabetic retinopathy for the treatment of the disease has been failing to reach diabetic people living in rural areas. The shortage of trained ophthalmologists, limited availability of healthcare centers, and expensiveness of diagnostic equipment are among the reasons. Although many deep learning-based automatic diagnosis of diabetic retinopathy techniques have been implemented in the literature, these methods still fail to provide a point-of-care diagnosis, and this raises the need for an independent diagnostic of diabetic retinopathy that can be used by a non-expert. Recently the usage of smartphones has been increasing across the world; automated diagnoses of diabetic retinopathy can be deployed on smartphones in order to provide an instant diagnosis to diabetic people residing in remote areas. In this paper, inception based convolutional neural network and binary decision tree-based ensemble of classifiers have been proposed and implemented to detect and classify diabetic retinopathy. The proposed method was imported to a smartphone application for further classification, which provides an easy and automatic system for diagnosis of diabetic retinopathy.
