Getting numbers out of Vision Builder

[aaron_pisces]

I am trying to set up an automated vision system using NI vision builder.  I want to find dark spots (defects), measure their area, and make a decision based on their aggregate area.  I can do the first two steps, but am having trouble with the third.

You may want to explain your application a little more, but I think that the first 2 steps can be handled in Vision Builder, and the last step needs to be programmed(manually) in Labview.

Perform your decision logic and reduce it to a boolean (true/false condition). Feed this boolean into a case statement and take the appropriate decison making steps within each case.
