Automatic Detection of Diabetic Retinopathy in Non-dilated RGB Retinal Fundus Images

In this paper, a method for automatic detection of microaneurysms in digital eye fundus image is described.To develop an automated diabetic retinopathy screening system, a detection of dark lesions in digital fundus photographs is needed.Microaneurysms are the first clinical sign of diabetic retinopathy and they appear small red dots on retinal fundus images.The number of microaneurysms is used to indicate the severity of the disease.Early microaneurysm detection can help reduce the incidence of blindness.Here, we have discussed a method for the automatic detection of Diabetic Retinopathy (ADDR) in color fundus images.Different preprocessing, feature extraction and classification algorithms are used.The performance of the automated system is assessed based on Sensitivity and Specificity.The Sensitivity and Specificity of this approach are 94.44 % and 87.5 %, respectively.
