Image and Vision Computing, 2009•ElsevierThe vascular structure of the retina consists of two kinds of vessels: arteries and veins.
Together these vessels form the vascular graph. In this paper, we present an approach to
separate arteries and veins based on a pre-segmentation and a few hand-labelled vessel
segments. We use a rule-based method to propagate the vessel labels through the vascular
graph. The anatomical characteristics of the vessels on the retina are modelled as a dual
constraint graph. We embed this task as double-layered constrained search problem …

The vascular structure of the retina consists of two kinds of vessels: arteries and veins. Together these vessels form the vascular graph. In this paper, we present an approach to separate arteries and veins based on a pre-segmentation and a few hand-labelled vessel segments. We use a rule-based method to propagate the vessel labels through the vascular graph. The anatomical characteristics of the vessels on the retina are modelled as a dual constraint graph. We embed this task as double-layered constrained search problem steered by a heuristical AC-3 algorithm to overcome the NP-hard computational complexity. Results are presented on vascular graphs generated from manual as well as on automatical segmentation.
