<br/><br/> We introduce a fast, simple, and an automatic hybrid approach, which extracts  the vascular structures. First, we introduce the hybrid filter that merges a vessel enhancement and a bifurcation detectors filters. Second, we integrate this hybrid  filter with a digital wave propagation system by mapping the filtered image to a cost image. A set of 40 fundus retinal images were used to study the enhancement gained by the hybrid filter and the wave propagation compared to  the vessel filters. The results of comparison show an enhancement up to  10%,15%, and 50% in the dice coefficient, sensitivity and the response at  bifurcation locations respectively
