<div dir="ltr">Hi Ivan,<div><br></div><div>It would need a few modifications:</div><div><br></div><div>First, save the transform parameters from your registration. I.e. GetParameters form your transform object (these might be the matrix numbers you are mentioning).</div><div><br></div><div>For applying the transform to a new image:</div><div>1. Read the transfrom parameters you saved</div><div>2. Instantiate a new transfrom object of the same type as the registration</div><div>3. Set the transfrom parameters with SetParmeters</div><div>4. Create a resampler and set the transform.</div><div>5. Apply the resampler to your new image</div><div><br></div><div>The resampler example provides the basic structure:</div><div><a href="https://itk.org/Wiki/ITK/Examples/ImageProcessing/ResampleImageFilter" target="_blank">https://itk.org/Wiki/ITK/<wbr>Examples/ImageProcessing/<wbr>ResampleImageFilter</a><br></div><div>You would need to change the code to use your specific transformation and set your saved transform parameters.</div><div><br></div><div>Alternatively you could modify ImageRegistration8.cxx to read additional images and apply the same resampler used for your image B to them.</div><div><br></div><div>Another option is to use Slicer3D <a href="https://www.slicer.org/" target="_blank">https://www.slicer.<wbr>org/</a>.</div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Jun 9, 2017 at 1:08 PM, Ivan Hidrovo <span dir="ltr"><<a href="mailto:ivan.hidrovo@gmail.com" target="_blank">ivan.hidrovo@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><div><div><div>Hello all,<br><br></div>We are registering 2 data sets A and B using ImageRegistration8.cxx.
