Neighborhood Connected (ITK)

Neighborhood Connected is a region growing method with two criteria:

1. The included pixels must have values between a Lower and Upper threshold.
2. All pixels in the neighborhood (within a specified pixel radius) must also be within the value range.

By the combination of these criteria small structures are less likely to be accepted in the region.

Multiple seed points can be specified by the use of markers.

and correspondingly multiple structures can be found at once.
