Within a distributed system, resources may be shared between nodes. The system should continue to operate eveni fi ndividual nodes fail due to hardware or software errors. This may result in the loss of resources that were hosted on the failed node, but it may be possible to continue to provide access to some resources by hosting them on another node. This(More)
We present a methodology for extracting the vascular network in the human retina using Dijkstra's shortest-path algorithm. Our method preserves vessel thickness, requires no manual intervention, and follows vessel branching naturally and efficiently. To test our method, we constructed a retinal video indirect ophthalmoscopy (VIO) image database from(More)
