[Insight-users] Help with GeodesicActiveContourImageFilter --> Modification to example code does not seem to work

[Juan Cardelino]

Hi guys,
            There is also the possibilty of directly using the
SignedDanielssonDistanceMapImageFilter which computes the level set
from a mask image. This masks defines whats inside the initial
contour.
Best,
        Juan
