<div class="">Is this by design? In the example script, both the input and the output for ConfidenceConnectedImageFilter are 3d floats…</div>

<div class="">If not, I would be happy to try to fix the issue and commit a fix if there are guidelines somewhere for doing so.</div>

<div class="">one good way to know which types are available is to use the <span style="background-color: rgba(255, 255, 255, 0);" class="">GetTypes method on your template (before calling New). This method way introduced in 4.7 or after, I don't remember.
But it is definitively available in 4.8 rc 1.</span></div>

<div class="">Hey all,
<div class=""><br class="">
</div>
<div class="">I’m just getting started with ITK, and I’m using the python bindings, which are really awesome. It looks like it was a fair bit of work to get such a heavily templated library to work in Python, but it’s really nice to be able to build scripts
in python!</div>
<div class=""><br class="">
</div>
<div class="">I set out to reimplement Slicer’s “Simple Region Growing Segmentation” using ITK-Python, but I keep getting an error when I try to define a ConfidenceConnectedImageFilter template on a 3d float (and double, too). IMG_F == itk.Image[itk.F, 3] elsewhere
in the script.</div>

<div class=""><br class="">

<div class="">Interestingly, I <i class="">can</i> build a CurvatureFlowImageFilter or a CastImageFilter templated against 3d floats. I can also instantiate a ConfidenceConnectedImageFilter templated against itk.UC (presumably unsigned char?). That made me
think that it’s not possible to build a ConfidenceConnectedImageFilter templated on floats, but the <a href="http://www.itk.org/Doxygen/html/Examples_2Segmentation_2ConfidenceConnected_8cxx-example.html#_a5" class="">ConfidenceConnected</a> example segmentation
script does just that.</div>

<div class="">I’d love to hear thought/suggestions as to how I can proceed!</div>
