[Insight-users] CMake Stack size

[Daniel Blezek]

Hi Mat,

  Flood fills don't have to be recursive.  It is much more efficient to
manage a stack (using stl::vector) of voxels than to use recursion.  Then no
worries about stack size for recursion.

  If you just want to figure out the area of a given object, you can use the
itkShapeLabelObject in the Review directory.
