| Automated Calculation of Retinal Arteriovenous Ratio for Detection and Monitoring of Cerebrovascular Disease Based on Assessment of Morphological Changes of Retinal Vascular System (2009) | |||||||||||||
Abstract | |||||||||||||
| In the frame of the ARIC study it could be shown that the retinal vessel system gives important information about retinal, ophthalmic, and cerebrovascular diseases by manually labeling the vessels. In this paper an approach is presented which automatically assesses the retinal vessel systems in fundus images. For this, first the optic disk is located. Afterwards the vessels are segmented and then classified into arteries and veins. In the last step an index, based on the ratio of the diameters of arteries and veins, for the risk of suffering a stroke is calculated. Introduction/Mot ivation According to the WHO stroke is the second frequent cause of death world-wide. In Germany stroke is the | |||||||||||||
