* '''Tolerance''': dynamic of intensity for the search of regional minima (in the extended-minima transform, which is the regional minima of the H-minima transform, value of h). Increasing the tolerance value reduces the number of segments in the final result, while decreasing its value produces more object splits.
* '''Calculate dams''': un-check this option to produce segmentations without watershed lines.
* '''Connectivity''': voxel connectivity (4-8 in 2D, and 6-26 in 3D). Selecting non-diagonal connectivity (4 or 6) usually provides more rounded objects.
