Hello everyone,

I'm very confident to bring things here a step further by transferring
some processing elements to ImageJ and I came across some points
concerning binary images.

I made a skeletonized version of an image and get lots of small dots or
masks (via Analyse Particles) with small areas of perhaps 1 to 8 px. It
would be relatively easy to filter them by the results table information
and delete corresponding masks from the selection (ROI Manager) i.e. via
macro.

But though this seems to be a very important step like De-speckle or
Median on typical images, I wonder If there are already tools/plug-ins
for that kind of purpose.

Maybe there are workflows/plugins for these szenarios:
- delete small dots/forks from binary/skeletonized images by area-size
- connect lines/forks via distance value


Any thoughts kindly appreciated.

Regards,
Rainer
