Embodiment Construction
[0066] The present invention will be described in detail below with reference to the drawings and specific embodiments.
[0067] This embodiment takes figure 1 The fundus image shown is taken as an example to illustrate the arteriovenous retina vessel classification method based on the fundus image, and the size of the fundus image is 3000×3000. There are bright rings in the fundus image due to the ring reflection caused by photography, the non-vascular step edge around the optic disc, patchy lesions, and hemorrhagic lesions.
[0068] The arteriovenous retinal vessel classification is performed on the fundus image, and the classification process is as follows: figure 2 shown, including the following steps:
[0069] (1) Obtain the global blood vessel set (i.e. the final blood vessel set) and the optic disc positioning information of the fundus image, the global blood vessel set is the collection of all blood vessels in the fundus image, and the optic disc positioning informa...
