Hi all, I was wondering if anyone knew a method of distinguishing/defining internal pore space from the surrounding medium/open space around an 3D clast/grain? The dataset I am working with is a 3D X-ray CT scan of a highly porous and irregularly shaped object. I have a feeling it may depend on how I define the ‘boundaries’ of my object but cant seem to find anything… can anyone help?
The image below is a slice taken from my z-stack in which the object I am interest in extracted the pore network from can be seen in white. Internal pore space and the surrounding free/open space is obviously black.
