TL;DR: In this article, a semi-automatic method to measure and quantify geometrical and topological properties of continuous vascular trees in clinical fundus images is described, where the skeletons of the segmented trees are produced by thinning, ff branch and crossing points are identified and segments of the trees are labeled and stored as a chain code.

TL;DR: In this paper, the second derivative of the intensity image is used as a feature for segmentation of blood vessels in retinal images, which gives information about its topology and overcomes the problem of image intensity variations.
