ABSTRACT
Exudates are one of the primary signs of diabetic retinopathy, which is a main cause of blindness and can be prevented with an early screening process. Diabetic retinopathy eye disease is harmful; causes pressure in eye nerve fibre. It is essential to diagnose it earlier. In this paper we have process on images of retina with the help of Digital Image Processing (DIP) tool in which images are detected and then processed. At last we describe the problem of detecting edges in images as a diabetic retinopathy (DR), macular degeneration and glaucoma. The edge detection problem can be separated into three stages: filtering; detection; and tracing and images separated with the application of different algorithm based on local pixel characteristics which can control the degree of Gaussian smoothing. Filtered images are then applied to a simple edge detection algorithm which evaluates the edge fuzzy association value for each pixel; based on local image characteristics.
