Abstract
A method, device and apparatus for differentiating arteries and veins of retinal vessels are provided. The method includes acquiring a vessel extraction image, a fundus image, and optic disc center coordinate; extracting a main vessel according to the vessel extraction image, the fundus image and the optic disc center coordinate to obtain a main vessel image, and intercepting the main vessel based on the main vessel image to obtain multiple single vessel segments; measuring diameters of the multiple single vessel segments to obtain diameter sizes of the multiple single vessel segments, obtaining multiple artery-vein vessel pairs according to the diameter sizes.
