Dear Tim,<br>I don't really know whether pipelining so many optimzers makes sense, but as long as it makes sense, you can use as many filters as you wish (or as many as your RAM memory can handle when the space allocated for the IO starts to grow) in your ITK program. By all means.<br>
<br>That's the crux of ITK. In fact, if you look at the <a href="http://www.itk.org/ItkSoftwareGuide.pdf">ITK software guide</a>, it is full of such examples.<br><br>Kind regards,<br>JON HAITZ<br clear="all"><br><br><div class="gmail_quote">

Hello,<br><br>I am working on a modified version of DeformableRegistration15... I would like to use different optimizers at each step if the registration process (registration steps are: Rigid->Affine->BSplineCoarse->BSplineFine, and I would like to use the following optimizers: VersorRigid3DTransformOptimizer->RegGradStepOptimizer->LBFGSBOptimizer->LBFGSBOptimizer), as I believe different optimizers for each step make sense.<br>
<br>I haven't seen any sample programs with multiple filters used throughout - could someone tell me if it is a big issue to try and instantiate two filter objects and use them at different points in the pipeline?<br>
