<div dir="ltr">hello David,<div><br></div><div>I find this very interesting and it would help me a lot. However, I seem to be having trouble with importing the python binding libraries for these classes. Ive set the PYTHONPATH to the directory where the "airs.py" is located and i get an error like:</div>
<div><div>import error loading library vtkImageAnalysisPython</div><div>import error loading library vtkImageRegistrationPython</div><div>import error loading library vtkImageSegmentationPython</div></div><div><br></div>

Any ideas how to get around this ? sorry for the trouble.</div><div><br></div><div>jatin</div><div><br></div></div><div class="gmail_extra"><br><br><div class="gmail_quote">On Wed, Apr 16, 2014 at 4:54 PM, David Gobbi <span dir="ltr"><<a href="mailto:david.gobbi@gmail.com" target="_blank">david.gobbi@gmail.com</a>></span> wrote:<br>

to put this project on hold while I work on other projects.<br>
<br>
But to get you started, from python you would use it something like this:<br>
<br>
import vtk<br>
import airs<br>
<br>
... load the images ...<br>
<br>
registration = vtk.vtkImageRegistration()<br>
registration.SetFixedImage(targetImage)<br>
registration.SetMovingImage(sourceImage)<br>
... set other registration parameters ...<br>
<br>
while (registration.Iterate()):<br>
# Iterate() returns "false" when it is done<br>
print "did an iteration"<br>
<br>
transform = registration.GetTransform()<br>
<br>
See the main header "vtkImageRegistration.h" for more info.<br>
