Nerve Detection Module

" + "

Prerequisites

" + "
    " + "
  • Setup or load an apropriate model. The model only defines the classnames, no training is required.
  • " + "
  • Load a skin biopsy image from Orbit
  • " + "
  • Activate the nerve detection module (Tools->Nerve Detection Module)
  • " + "
" + "

Model definition

" + "
    " + "
  • Define model classes like '1x corssing', '2x crossing', ... and an additional 'other' class.
  • " + "
  • Later assign all wrong detected residues to this 'other' class.
  • " + "
" + "

Fluorescence Images

" + "
    " + "
  • Ensure that the nerves are in red channel.
  • " + "
  • Open the module option menu and check the 'Fluorescence Image' option.
  • " + "
" + "

Detect new nerve segments

" + "
    " + "
  • Click the 'Detect' button. This will detect nerve segments and list these spots in the list.
    You can also mark a region of interest (ROI) before spot detection to get fast results for a smaller region.
  • " + "
  • You can click on the 'Save' button to save detected spots.
  • " + "
" + "

Filter junction crossing nerves

" + "
    " + "
  • Activate the 'Annotation' tab.
  • " + "
  • In the Annotation->Options menu, uncheck 'close polygons' (for a nicer display).
  • " + "
  • Click on add polygon and draw the junction.
  • " + "
  • You might continue and draw the junction several steps (click again on 'add polygon'). When finished, click on 'Options->Combine Polygons' to merge the junction segments to a single path.
  • " + "
  • Select the junction annotation, click on 'edit' and rename it to 'junction'. This is very important, because the nerve detection module will search for an annotation called 'junction' (otherwise it will do the nerve detection on the whole image). You might give it also another color.
  • " + "
  • Go back to the nerve detection tab, select a ROI around the junction and click on 'detect'.
  • " + "
  • Remark: The old annotations are automatically removed from the database and the new combined one is automatically stored in the database.
  • " + "
" + "

Load existing nerve segments

" + "
    " + "
  • Click on the 'Load' button to see if already detected spots have been persisted and load them.
  • " + "
" + "

Quantify nerve classes

" + "
    " + "
  1. Click on 'Shuffle' to shuffle the list. This is necessary to achieve unbiased results.
  2. " + "
  3. Click on the first spot entry in the list.
  4. " + "
  5. Use the keyboard and press a number (e.g. 1-3) to assign the selected spot a class.
    The selection will automatically jump to the next spot. By holding down the ctrl key you can prevent this and the selection will stay on the selected item.
  6. " + "
  7. Use specific classes only when you are sure. Otherwise select the 'other' class. These spots will later be excluded from the statistics.
  8. " + "
  9. Use backspace to reset the spot class (set to undefined).
  10. " + "
  11. Once you think you classified enough samples, click on 'Statistics' to retrieve a classification statistic.
  12. " + "
  13. Click on 'Save' to persist your classifications. You can always continue with the classification by pressing the 'Load' button, shuffle your list and continue the classification.
