Dear Cora,
First threshold your image and later click "Set Measurements" under
"Analyze" menu
Select only the area for your measurements.
Then select the area which you want to measure by the "Freehand selection
tool" and click "Analyze particles" under "Analyze" menu.
If you want to exclude area on edges of your selection you will also find a
box about this on the opened window.

Subject: Porosity Measurement
Hi Dear All,
I have a simple question for experts like you (it's
difficult so far for me)
I have a picture in not rectangular or square form.
When I open it and convert it to binary then measure
the porosity it takes the area of whole picture
(picture itself+plus white background that fills the
rectangular. Is there any way to get porosity
measurement for irregular shapes excluding the
background?
Thanks in advance...
