Hello,
<div class=""><br class="">
</div>
<div class="">I have some SimpleITK tests which do verify that this optimizer does produce the “iteration event”.</div>
<div class=""><br class="">
</div>
<div class="">I don’t recall the details of this optimizer, but I think it does a complex update step and may not report the event if it terminates early. I suspect there is a problem with how the registration problem is setup which causes the optimizer not
work and not a problem with the ITK code.</div>
<div class=""><br class="">
</div>
<div class="">What is the “stop condition description”?</div>
<div class=""><br class="">
</div>

<div dir="ltr" class="">Hi, hope someone can help direct me to a reference.
<div class="">I have been trying to use the PowellOptimizerv4 to do an automated image alignment between two 3D ultrasound images. We are using Mutual Information as a metric and it is exiting at -0.30 for images with a high degree of overlap, but when I use CommandIterationUpdate
to try and see how the optimizer is behaving the Execute() method doesn't run. It is identical to the code copied from ITK examples that ran when I was using the LBFGS optimizer, with the exception that I've added a few print statements to see whether one
of the if statements was being activated prior to the output.</div>
<div class=""><br class="">
</div>
<div class="">Let me know if you have any suggestions, thanks.<br clear="all" class="">
