[Insight-users] Need a clarification about ConnectedComponentImageFilter

[robert tamburo]

Connectivity is the only criteria for ConnectedComponentImageFilter

The below include intensity:

You can also define your own criteria in an ImageFunction and use it with a
FloodFilledImageFunctionConditionalIterator-- which is how the *Connected*
filters function. An example of how to do this is here:
