Try this simple macro that works on the current image
Or do the sequence by hand
1) make binary, the original is not a binary image
2) join broken connections Process/Binary/Options/closing you may want to change the number of iterations
3) threshold again and then use analyze particles to measure the area and place this in the results window. Analyze/set measurements decides what to measure
setAutoThreshold("Default dark");
setOption("BlackBackground", true);
run("Convert to Mask");
// join broken connections
run("Options...", "iterations=4 count=1 black do=Close");
setAutoThreshold("Default");
run("Set Measurements...", "area area_fraction redirect=None decimal=4");
run("Analyze Particles...", "display exclude clear summarize add");
run("Analyze Particles...", "exclude summarize add");

Subject: Finding the regions automatically
Hello,
Greetings of the day!
I have a binary image, and want to find the area of each of the domains. I can do that with nearest neighbor tool by selecting each domain and to add in roiManager, and then to measure the area of each domain.
I want to know is there any other way so that the selection of the domains can be done automatically?
For convenience, attaching the binary image (a_75) and the output image obtained from nearest neighbor tool showing one domain in red color. Your help will be appreciated!
Thanks in advance!
Anu
