Abstract
An accurate and fully automatic method to measure the vessel width at branching points in fundus images is
presented. This method is a graph-based method, in which an electric field theory based graph construction
method is applied to specifically deal with the complicated branching patterns. The vessel centerline image
is used as the initial segmentation. The branching points are detected on the vessel centerline image using a
series of detection kernels. Crossing points are distinguished from branching points and excluded in this study.
Electric field theory motivated graph construction method is applied to construct the graph, inspired by the
non-intersecting property of the electric line of force. Of the three branches in a branching unit, the one closest
to the optic disc is automatically detected as the parent branch and the other two are regarded as the daughter
branches. The location of the optic disc is automatically detected based on a machine learning technique. The
method was validated on a set of 50 fundus images.
