<div><br></div>Hi Lydia,<div><br></div><div>In ITKv4, the registration framework that existed for ITKv3</div><div>is still fully functional and it is tested on a nightly basis in</div><div>many platforms. There shouldn't be any computation time</div>
<div>change in this code between ITKv3 and ITKv4.</div><div><br></div><div>Could you please give us more details on the registration</div><div>components that you are using ?</div><div><br></div><div>1) Metric</div><div>2) Optimizer</div>
<div>3) Interpolator</div><div>4) Transform</div><div><br></div><div>Information about your platform will also be very useful:</div><div><br></div><div>a) Compiler (VC, gcc, ic ?)</div><div>b) Architecture (Win/Mac/Linux)</div>
<div>c) Amount of RAM memory</div><div>d) Compilation mode : Debug / Release / Other ?</div><div>e) Processor: Number of Cores (how many get used ?)</div><div><br></div><div><br></div><div>and description of the images that you are using:</div>
<div><br></div><div>i) Image size in pixels</div><div>ii) Image dimension (2D, 3D)</div><div><br></div><div><br></div><div>Ideally, </div><div>if you can share your source with use, </div><div>we will be able to help you a lot faster.</div>
<div><br></div><div><br></div><div>Finally, regarding the ITKv4 registration framework, </div><div>you may find useful the following materials that have </div><div>been used in Conference tutorials in MICCAI 2011 and</div>

<br>
we try to register MRI data with ITK 4.<br>
So far, we can run an algorithm migrated from ITK 3 (no compatibility mode) but with a tremendous increase in runtime. For this, we don't have an explanation. So, we looked around and found the new registration stuff ...v4 but couldn't find any example for it.<br>
Are there somewhere new examples explaining these methods in more details?<br>
<br>
Thanks a lot in advance<br>
Lydia<br>
