Review on: Blood Vessel Extraction and Eye Retinopathy Detection

Diabetic retinopathy eye disease which is harmful; cuases pressure in eye nerve fiber. It is essential to diagnose it earlier. And this paper we have process on images of retina with the help of Digital Image Processing (DIP) tool. Therefore in which images are getting detected and then processed. At last we distinguish 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 [1]. 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.
