Hello, Kathrin,

  Check the "add to manager" box in "Analyze Particle" window.  All the detected objects will be stored in the ROI manager. Then you can do the measurements you prefer for each object.

Subject: problems with the function: analyse particles

Dear helper,

I am a beginner in working with ImageJ. I would be happy if someone can help me with my problem.

I am using microscopy pictures of a polished structure and want to determine the porousness of the samples.
I  checked the user guide and as far I can transform the image to a greyscale and set the treshhold. As I know these are the points I have to do before using "analyse particles".  If I do this, as a result I get the area percentage of all particles compared to the whole area. But is it possible to get the area percentage of every single particle?

Thanks in regard.
Sincerely yours,

 

Kathrin Kolotzek
