Connectivity is the only criteria for ConnectedComponentImageFilter<div><br></div><div>The below include intensity:</div><div><a href="http://www.itk.org/Doxygen/html/classitk_1_1ConfidenceConnectedImageFilter.html#details" target="_blank">http://www.itk.org/Doxygen/html/classitk_1_1ConfidenceConnectedImageFilter.html#details</a></div>

<div>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: <a href="http://www.itk.org/Wiki/ITK/Examples/WishList/Iterators/FloodFillIterator">http://www.itk.org/Wiki/ITK/Examples/WishList/Iterators/FloodFillIterator</a></div>
