Published Paper Details:

The retina has two sources of oxygen and nutrients: the retinal blood vessels and the choroid, which lies under the retinal pigment epithelium. The blood vessels within the retina itself that carry oxygen and nutrients are called arteries. Blood vessel is also very useful in tracking of disease progression. Assessment of blood vessels network plays an important role in a variety of medical disorders. Detection and quantitative measurement of variations in the retinal blood vessels can help diagnose several diseases including diabetic retinopathy. Morphological operation to smoothen the background, Disc structuring elements were used in this work. The proposed algorithm has employed modules such as gray scale conversation, contrast enhancement, morphological operation .The techniques describe in the paper is based on morphological operation and apply on the publicly available DRIVE and STARE datasets. An average accuracy of 0.96 has been respectively achieved on the DRIVE and STARE datasets, which are not only greater than most methods, but are also superior to the second human observer's performance. Paper mainly describes effect of contrast enhancement in detection of blood vessels. The results show that the proposed method gives good results with less time complexity.
