Four Severity Levels for Grading the Tortuosity of a Retinal Fundus Image

Journal of Imaging, 2022
Hypertensive retinopathy severity classification is proportionally related to tortuosity severity grading. No tortuosity severity scale enables a computer-aided system to classify the tortuosity severity of a retinal image. This work aimed to introduce a
