I have a stack of images of my soil (taken by x-ray tomography) that looks like the image below sandpack04_1000x1000x1000_8bit2.to-byte101.tif (7.0 KB)
Where the black 'circle’s are the particles/grains of the soil. I’m struggling to find a way to obtain surface roughness (e.g. Ra values) and sphericity measurements of grain particles in a soil sample from 2D stacked images by using imagej/fiji. Is there any way to obtain surface roughness and sphericity values of a grain particle in 3D? I tried doing to do particle analyzer to first identify the particles and then use the Roughness Calculation plugin, however, this only identifies the grain particles per slices and I want it to identify the grain particles in 3D. For sphericity, I tried using the 3D Shape Measure but it didn’t identify the grain particles.
Thanks in advance!
