Validation Study on Retinal Vessel Caliber Measurement Technique

Changes in retinal vessel caliber are associated with several diseases, such as diabetes and hypertension. The robust assessment of abnormality on vessels with different sizes is a challenging task. In this paper, we propose a robust and reliable method for the measurement of retinal vessel caliber. The method is validated on a dataset where the optic disc centered images are acquired using 6 different fundus cameras with a repetitive acquisitions. The results are compared with the semiautomatic software IVAN, where the relative errors are similar.
