Hello,
<div class=""><br class="">
</div>
<div class="">My assumption would be that the error is in physical space and not pixels as this is standard ITK practice. While the documentation is rather sparse you can look at the source code to gain insight into these types of questions [1].</div>
<div class=""><br class="">
</div>
<div class="">Also note that there is the InverseDisplacementFieldImageFilter. I don’t recall the difference and if one is generally preferred of the other.</div>
<div class=""><br class="">
</div>
<div class="">HTH,</div>
<div class="">Brad</div>
