I was looking at the documentation for Purify and Connectivity.
I notice purify doc mentions that connectivity assumes no cavities in the image.
Currently, I am using this on microCT images of mouse Tibia. I threshold imagjes and use clear outside to to leave on trabecular segment behind. I then apply purify and then connectivity.
This a snapshot of purified segment.
As you can see the middle is empty, which fits with original scan image.
I was wondering if this is a problem.
