<div dir="ltr">Hi, hope someone can help direct me to a reference.<div>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><br></div><div>Let me know if you have any suggestions, thanks.<br clear="all"><div><div class="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><p>--</p><p>AH<br></p><p><br></p><p>-----------------------------------------------------------------------------------------------</p><p><i>This email and any attachments thereto may contain private, confidential, and privileged materials for the sole use of the intended recipient.
