[ITK] [ITK-users] PowellOptimizerv4 does not run CommandIterationUpdate Execute() method

[Andrew Harris]

Hi, hope someone can help direct me to a reference.
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.

Let me know if you have any suggestions, thanks.
