Merger ModeΒΆ

With the Merger Mode tool, individual segments (for example from over-segmentation) can be combined ("merged") to refine a segmentation and fix split errors.

To use the Merger Mode:

  1. From the toolbar, switch to the Skeleton Tool
  2. From the toolbar, enable the "Merger Mode" modifier (double arrow icon)
  3. Mark connected segments by left-clicking and placing nodes in the corresponding segments. This creates a skeleton annotation. Segments connected through that skeleton annotation will be merged. To combine multiple segments, ensure all "correcting nodes" belong to the same tree.

Please note, Merger Mode is a lightweight correction workflow. WEBKNOSSOS does not directly modify the underlying segmentation while you trace. Instead, corrections are applied in real time based on the current skeleton annotation. Disabling Merger Mode shows the original segmentation; re-enabling it reapplies your corrections.

After finishing the proofreading, a long-running job can be started to apply the merging of segments into a new dataset with the same layers. The job can be started by clicking the "Materialize" button next to the merger mode button in the toolbar.
