[ITK-users] Entropy Feature image and Active contour for bone segmentation

[Matt McCormick]

Hi vis,

Yes, that seems like a reasonable approach.

The feature image may need to be processed so it has the desired
properties.  See the file

  ITK/Examples/Segmentation/GeodesicActiveContourImageFilter.cxx

for an example.

HTH,
Matt
