Analyzing the Retinal Blood Vessels Extraction and Bifurcation Points in Color Retina Fundus Image

The extraction of retinal blood vessels in retinal fundus images can help the physicians for purpose of diagnosing diseases such as diabetes, hypertension, patients screening, diabetes retinopathy (DOR) has been subjected of several large scale clinical studies. Proposed algorithm efficiently extract and measure the blood vessel of retina and find the bifurcation points of retinal blood vessels is general enough that can be applied to high resolution ocular fundus image. Proposed algorithm has employed modulus such as pre-processing, 2D Median Filter, Morphological Operations, Thresholding and minutiae technique to find bifurcation points of extracted blood vessel. Proposed algorithm is being simple and easy to implement ,is best suited for fast processing applications.
