SEM Image Porosity and Pore Size

The code takes gray-scale SEM images and gives back its porosity and pore size distribution

Extraction of porosity and pore size distribution from SEM images

We assume that the input SEM images are gray-scale and darker parts of the image
shows deeper surfaces which are considered as pore spaces

Hints:
if your image has got a transparency layer (alpha) you need to remove it.
Also, if the image has got the black subtitle bar, it should be removed before feeding to the code.
Let me know if you ran into a problem.
