  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...
