摘要：Diabetic retinopathy is one of the pre-eminent causes of blindness among the diabetic affected patient. Itis caused by the light sensitive tissue in the retina because of the damaged blood vessels.The substances of lipoproteingets leaked out of the blood vessels which are damaged and are deposited in the intra retinal part. The nerves of opticsbeneath the substances are interrupt from being excited by rays of light and are failed to produce any nerve impulse tobrain and leads to loss of vision partially. Exudates are the one which is a lipoprotein substancein the retinal regionwhich are yellow in colour.It is the important symptom of the retinopathy disease. Final stage detection of theretinopathy leads to loss of vision completely .By visual inspection, it is very difficult to detect exudates. In this paper,different image processing methods , include image thresholding,median filtering,morphological process areinvolved.By counting the number of affected cell in the retina by selecting the region of interest ,it shows theoccurrence of retinopathy diseases.
