A demonstration of the effect of increased image resolution on the intermediate result and how the refinement iterations mitigate this effect, using dataset Lymphatic 1: An increased image resolution highly increases the number of erroneous branches (in this example the total number of branches is increased roughly 60-fold). After 5 refinement iterations the resulting graph is very similar to the graph extracted from the original volume without artificially increased resolution. Centerlines are rendered as red lines. Nodes in the graph (end or branching points) are rendered as black spheres, which in (b) due to the extremely large number of spurious branches obscure most of the centerlines
