[Insight-users] How to monitor ICP registration

[John Tourtellott]

I am trying to figure out why my ICP application isn't converging at the 
optimal solution. I tried using an Observer/Command, but the 
LevenbergMarquardtOptimizer class doesn't seem to invoke iteration 
events. Is that right, or am I doing something wrong?

And if that optimizer doesn't generate iteration events, is there any 
other way to track the progress of an ICP registration?

Thanks,
john
