An unsupervised coarse-to-fine algorithm for blood vessel segmentation in fundus images

作者:

Highlights:

• An unsupervised method to detect blood vessels in fundus images is proposed.

• The algorithm effectively tackles image distortions such as central vessel reflex.

• The two expert vessel identification images present significant differences.

• The average observer plays an important role in defining a neutral standard.

• Balanced accuracy is an alternative for performance evaluation of segmentation.
