The symptoms of some diseases such as high blood pressure and diabetic retinopathy affect on the retinal vessels can be helpful to control the progress of these diseases. In this paper, our aim is to detect and classify the retinal vessels to arteries and veins. This algorithm achieves the vascular tree structure using a local entropy-based thresholding segmentation method. Next, several color and...
<?Pub Dtl?>A decreased ratio of the width of retinal arteries to veins [arteriolar-to-venular diameter ratio (AVR)], is well established as predictive of cerebral atrophy, stroke and other cardiovascular events in adults. Tortuous and dilated arteries and veins, as well as decreased AVR are also markers for plus disease in retinopathy of prematurity. This work presents an automated method to...
Abnormalities in the retinal vessel tree are associated with different pathologies. Usually, they affect arteries and veins differently. In this regard, the arteriovenous ratio(AVR) is a measure of retinal vessel caliber, widely used in medicine to study the influence of these irregularities in disease evolution. Hence, the development of an automatic tool for AVR computation as well as any other...
