NEIGHBORHOOD CONNECTED is a region growing method which applies two grouping criteria:
1.An included pixel must have a value in the range between the Lower and Upper threshold.
2.All pixels in its neighborhood within the 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.
A single seed is provided by the triangulation point of the orthogonal planes. Multiple seed points can be specified by the use of markers.
The number of structures found depends on the number of seeds.
