Method for Finding the Limits of Blood Vessel Landmarks in Eye Fundus Images Based on Distances in Graphs: Preliminary Results

The paper proposes a method to process blood vessel landmarks in eye fundus images. The proposed method is based on finding a shortest cycle in a weighted graph, corresponding to a set of possible tracked blood vessel slices and paths between them. In turn, the paths are found by finding a shortest path in a weighted graph, taking gradients into account. The method has been tried out with DRIVE and IOSTAR databases.
