Exudates are the primary signs if diabetic retinopathy which are mainly cause blindness. Diabetic retinopathy is a complication of diabetes that caused by changes in the blood vessels of the retina. It is one of the earliest and most prevalent symptoms of diseases leading to blindness such as diabetic retinopathy and wet macular degeneration. Hence, detection of exudates is an important diagnostic task. In this project, we extract the blood vessels using thresholding method and detect optic disc using circular Hough transform method. Finally we detect the exudates using adaptive thresholding method in fundus image.
