<div>Hello.</div>
<div>I am using an amoeba optimizer to minimize overlap (itkKappaStatistic) between 2 binary volumes.</div>
<div> </div>
<div>My problem is that it seems that when i set parameters </div>
<div>optimizer->SetMaximumNumberOfIterations(1);</div>
<div>optimizer->SetParametersConvergenceTolerance(10);<br>optimizer->SetFunctionConvergenceTolerance(10);</div>
<div> </div>
<div>they dont seem to have any affect at all. Even though i tell it to maximal do 1 iteration, it still does 17 iterations in the first layer of my itkMultiResolutionImageRegistrationMethod.</div>
<div> </div>
<div>Furthermore, as i am doing kappastatistic, the maximum function value is of course 1 for perfectly</div>
<div>gemetric aligned images. So the function value is -1 all the time(Because i told the optimizer to maximize and not nminimize. But still, it does first convergeafter the 17 iterationss in the top pyramid. And the same for the rest of the pyramid.
</div>
<div>Here is the result from a 2-layered pyramid.......</div>
