[vtkusers] Convert to binary image

[Hila Hiler]

Gonzalo,
I use Mitk.
I don't understand how you want to run a vtkFilter on mitk::Image. why?
a vtkFilter you can run on mitk::Surface or mitk::Surface->getVtkPolyData();

if you have an itk::Image and you want to do a segmentation such that only
positive values will be in that seg, you can use iterator as David
suggested or you can use the GUI of mitk:
right click on the image that u loaded->set threshold value to zero-> and
you will get a segmented image.

Hope I helped.
