Abstract:
Diabetic retinopathy is the complications of diabetes, which can eventually lead to blindness. To prevent from blindness of diabetic patient an early detection of diabetic retinopathy is very important. As exudates are the early sign of diabetic retinopathy, we can save diabetic patient from blindness by detecting exudates. In this paper, we have developed an improved method of automatic exudates detection in retinal images using nonlinear background elimination.

Keywords: Diabetic retinopathy, hard exudates, soft exudates, microaneurysm and blindness
