Dear ImageJ users,

I’m completely new to using ImageJ, so I hope my question is not too easy. I’m currently using ImageJ to analyse SEM pictures of 3D prints that I make. The network that I print, has hexagonal shaped throughpores, as you can see in the images I will add in the next post (upload is failing now…). The largest structures that I print have quite nice throughpores, but the smallest structures (pushing the resolution limit of the printer) have deviant shapes. I’m trying to quantify how ideally shaped the throughpores are (of the 7 central hexagons only). I used the freehand selection to contour them, and then using a treshold to measure the area and perimeter. However playing with these parameters does not give a satisfied result. Now I want to compare the effective perimeter (drawn by hand containing all the deviations) with a hexagon that I draw between all the six corners. For the largest structures, the difference/variance/(1-overlap) should be minimal, and for the smallest structures bigger. Is there a way to measure this value?

Thank you in advance,

Kind regards,

Fréderick
