hi,

I'm sorry if this issue has been raised before.
I was using Otsu's mothod to threshold a fracture in a rock sample.
However, it appears that the threshold underestimates fracture aperture
adjacent to high density zones. Is there any technique to solve this kind
of problem?
Any help is appreciated!

Thank you

SD
