GeodesicDilation

GeodesicDilation[marker, mask]
gives the fixed point of the geodesic dilation of the image marker constrained by the image mask.

GeodesicDilation[marker, mask] effectively starts with marker, then repeatedly dilates it, masking with mask, until the result no longer changes.

GeodesicDilation[marker, mask, n] iterates the dilation process at most n times.

GeodesicDilation effectively performs a morphological reconstruction by dilation.

If multiple image channels are present, GeodesicDilation operates on each of them separately.
