Binary filters issues with ImageJ 1.51o

Hi everybody. I have troubles when aplying binary filters since last Fiji update.

  • Erode works as Dilate
  • Dilate works as Erode
  • Watershed doesn´t work as used (it looks like Voronoi)
  • Voronoi doesn´t show anything

Do you have any suggestion about what can I do? I have reinstalled Fiji but the issues persist. Thank you very much in advance for your help


Dear @SMC_CNB,

could you please check under Process > Binary > Options what your option for the Black Background is set? Try to invert you selection there.



You are absolutely right!!!

I had the option Black Background unchecked. Now I have tried with this option checked and all the filters work perfectly
Thanks a lot!!!
