[Insight-users] Equivalent of vtkContourFilter in ITK?

[kent williams]

I'm currently using vtkContourFilter to convert a binary image into a
set of contour polylines for my image tracing application.  So I was
wondering, is there an all-ITK way to do the same thing? i.e.

BinaryImage ---> ??? ---> set of polylines defining outline of mask regions.

In my particular case, I'm looking for contours on 2D slices of a 3D image.

I looked around for a while in the ITK documentation and saw nothing like this.

The main reason to want to do this is that while my particular
application is going to require VTK anyway, there are non-interactive
applications for this sort of thing that doesn't need to drag VTK
along for any other reason...
