Abstract

To enhance the image with imbalanced local illumination caused by retinal diseases in the process of fundus image acquisition, this paper proposed a new unsupervised retinal vessel segmentation method with morphological and Otsu. First, it used the combine of the top-hat transformation and the bottom-hat transformation to enhance the contrast between the blood vessels and its background in a retinal image. Next, it presented a novel revised method to remove the problem, which was caused by the imbalanced local illumination in the enhanced retinal image. Finally, it applied the threshold calculated by Otsu method to extract the retinal vessels. This paper evaluated the algorithm with two publicly retinal image databases DRIVE and STARE. The experiment results indicate that the segmentation accuracy in DRIVE database achieves 0.938 2, the segmentation accuracy in the STARE database achieves 0.946 0. The run time of this new method is 1.6 s. The new algorithm can accurately extract the retinal vessels. Compared with the traditional retinal vessel segmentation algorithm, its segmentation accuracy and anti-perturbation ability improve.
