A survey on Separation of Blood Vessels for detecting Retinal Vascular Disorders

Separating vascular from the retinal image is essential for detecting many retinal vascular disorders. Diseases which are all affecting the blood vessels of the eye are known as Retinal vascular disorders. Vessel separation of retinal image is a fundamental step in finding the affected area of vascular. Retinal Blood Vessel Separation (RBVS) is necessary for identifying diseases and changes in the retina. For segmenting the blood vessel and early detection of these disorders many different approaches and algorithms have been developed; few of them were discussed in this paper. In this paper, various existing techniques, methodologies, and algorithms for separating the vessels from the retinal image were analyzed. This paper also provides the summary of various existing techniques based on Segmentation methodology, performance matrices, and databases used.
