NI vision assistant to remove support from our parts

Hello,

I would like to get a reliable method to remove the support from our parts taken by vision.

I can't find a reliable way to do it.

I would like to see the result (See image Ref)
I have several images taken in different positions (A B C D E F)

Can you give me an effective procedure for obtaining the REF image in all cases and then extracting the contours?
