[Matthias Kirsch]

Dear all,

I have objects in a segemented image, each of them having a distinct grey level (see images below): How do I get them outlined individually.
Thanks so much for any sugegstion.

Hi Matthias,
assuming your grey level image is 8-bit, you could run something like the
following macro:

for (i=0;i<256;i++) {
  setThreshold(i, i);
  run("Create Selection");
  if (selectionType>0){
    roiManager("Add");
    run ("Select None");
  }
}

Sincerely,
Jerome
