Abstract
Diabetic retinopathy is a disease caused due to untreated diabetes for a long period of time. This disease is increasing world-wide and is a major reason for blindness. The effective way of cure for this disease is to detect it at an early state. Even though there are different types of screening techniques but there is still scope for improvements. One of the way to improve the accuracy is by concentrating more on the factors present in the eye which helps in determining the stages of diabetic retinopathy, and secondly by using pre-trained deep convolution deep neural network which can reduce the cost of training. In this paper we have experimented with different types of pre-processing techniques and their effects on enhancing the model performance. Finally the enhanced images were classified using pre-trained models. Total six pre-trained models were used out of which three were fine-tuned namely ResNet-50, Inception-v3 and InceptionResNet-v2 and the rest were used as conventional transfer learning models namely Inception-v4, DenseNet-169 and DenseNet-201. A brief comparison was drawn between the fine-tuned models and the conventional models, using the evaluation metrics like accuracy, validation accuracy and model loss. From the above mentioned experimentation we can conclude that preprocessed images along with fine-tuned pre-trained models are the best combination for diabetic retinopathy classification.
