The evaluation of retinal blood vessel diameter is associated with the diagnosis of diabetes, hypertension, arteriosclerosis, stroke, etc. A retinal arteriovenous ratio (AVR) is used for diagnosis of hypertension and arteriosclerosis. We propose a tracking method of the boundary of the retinal blood vessel on eye fundus image with low visibility, and then an automatic evaluation of AVR. In this study, the effectiveness of the proposed method has been proved through the experiments for the actual retinal images of cataract patients.
