Segmentation accuracies for 5 density maps simulated at various resolutions (6Å-30Å, every 2Å). The highest segmentation accuracy (blue lines) and highest maximum watershed segmentation accuracy (dashed red lines) amongst all components in each density map is plotted vs. resolution. The plots show that segmentation accuracies drop as the resolution increases, and that at low resolutions, the accuracies obtained by multi-scale grouping are the same as the maximum watershed accuracies.
