Hi everybody,

i am using the itkGeodesicActiveContourLevelSetImageFilter to segment a
region in my images.
In the GeodesicActiveContourImageFilter.cxx example the resulting image
is the whole segmented region.
Thats nice so far but i only want the outer contour of my segmented
region, to draw it in the original image.
For the contour is concave it is difficult to iterate through the binary
image an extract it.
Is there a good way to extract the outer contour and draw it in my
original image?

Thank You

Matthias
