Abstract
The complication of blood pressure and diabetes can affect various parts of the body. Diabetes and high blood pressure are major causes of blindness in the world. Due to high blood pressure and blockage in the blood flow causes swelling in ocular fundus which may leads to the formation of exudates. To diagnose the swelling in the retinal blood vessels and extract the features various methods are already proposed which are not clear. This paper proposes an efficient extraction of blood vessels and segmentation of exudates. In the proposed technique, the retinal image is initially super-resoluted and then the green plane is separated for accurate vessel extraction. Morphology operators using multi structure elements are applied to the enhanced image in order to find the retinal image ridges and reconstruction is performed to eliminate the ridges that are not belonging to the vessel tree while thin vessels remain unchanged. Segmentation using fuzzy clustering technique is performed for exudates detection.
