Segmentation of Blood Vessels from Fundus Retinal Images by Using Gabor Transformation

In this paper, it was using segmentation based on Gabor transformation for extraction the retinal blood vessels. The algorithm has been applied on images from freely accessible DRIVE and STARE databases. The segmentation algorithm provides the possibility of automatic modeling and consequent extraction of the retinal vascular system. Resultant images are in the form of a binary map. An algorithm for calculating the value of the curvature of the retinal vessels and thus objectifying the tortuosity can be applied to these images.
