Good day,

with respect to the provided image I doubt that the spatial resolution
is sufficient for pore analysis. Furthermore, the image--though in
PNG-format--suffers from extreme compression artifacts.

Are the original images JPEG-compressed?
If yes, they aren't suited for serious analyses.

Best
