Happy new year first.

As I am a new user for ImageJ or FIJI, this question may be so simple for some of you guys. I am trying to generate microstructures using stochastic method by MATLAB code. first I want to find the porosity of 2D SEM image of a GDL attached here. Please let me know all steps that I need to follow for measuring the area fraction. As I know these steps are summarized as follows:
1- Drag the image to the software,
2- Set scaling
3- turning it into 8bit image
4- analyse particle
5- computation the area fraction.
First let me know am I right or not?
in the step 4, I don’t know how to do it and does it need to be filtered before thresholding or not? Moreover, void phase or pores should be specified by red color in thresholding or solid phase?
and why it doesn’t show me a reasonable porosity comparable what manufacturer presents?
Thank so much in advance for your efforts.
