Then supply your transform class instead of itkTranslationTransform to itkImageRegistrationMethodv4.</div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small" data-mce-style="font-family: verdana,sans-serif; font-size: small;"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small" data-mce-style="font-family: verdana,sans-serif; font-size: small;">Regards,</div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small" data-mce-style="font-family: verdana,sans-serif; font-size: small;">Dženan</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Sat, Sep 24, 2016 at 2:54 PM, Marc-Michel Rohé <span dir="ltr"><<a href="JAVASCRIPT-BLOCKED_e(%7B%7D,'cvml','marc-michel.rohe@inria.fr');" target="_blank" data-mce-href="JAVASCRIPT-BLOCKED_e(%7B%7D,'cvml','marc-michel.rohe@inria.fr');">marc-michel.rohe@inria.fr</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex" data-mce-style="margin: 0 0 0 .8ex; border-left: 1px #ccc solid; padding-left: 1ex;">Hello,<br> <br> I am working with the registration pipeline of ITK using 3D images. What I would like to do is to register two images with translations but keeping the translation with respect to the third dimension at 0 (so find the best 2D translation on the axis X and Y mapping two images).<br> <br> Is there a way to use the ITK classes "itkTranslationTransform" and "itkImageRegistrationMethodv4" ?<br> <br> I have looked at multiple examples and documentation but could not find a way to do it easily if not coding a whole new class that performs 2D transform in 3D...<br> <br> Thx !<br> _____________________________________<br> Powered by <a href="http://www.kitware.com" rel="noreferrer" target="_blank" data-mce-href="http://www.kitware.com">www.kitware.com</a><br> <br> Visit other Kitware open-source projects at<br> <a href="http://www.kitware.com/opensource/opensource.html" rel="noreferrer" target="_blank" data-mce-href="http://www.kitware.com/opensource/opensource.html">http://www.kitware.com/opensource/opensource.html</a><br> <br> Kitware offers ITK Training Courses, for more information visit:<br> <a href="http://www.kitware.com/products/protraining.php" rel="noreferrer" target="_blank" data-mce-href="http://www.kitware.com/products/protraining.php">http://www.kitware.com/products/protraining.php</a><br> <br> Please keep messages on-topic and check the ITK FAQ at:<br> <a href="http://www.itk.org/Wiki/ITK_FAQ" rel="noreferrer" target="_blank" data-mce-href="http://www.itk.org/Wiki/ITK_FAQ">http://www.itk.org/Wiki/ITK_FAQ</a><br> <br> Follow this link to subscribe/unsubscribe:<br> <a href="http://public.kitware.com/mailman/listinfo/insight-users" rel="noreferrer" target="_blank" data-mce-href="http://public.kitware.com/mailman/listinfo/insight-users">http://public.kitware.com/mailman/listinfo/insight-users</a><br></blockquote></div><br></div></blockquote><br><div><br></div>-- <br><div><br></div>brian<br><div><br></div><br></blockquote><div><br></div></div></body></html>
