<br>Hi John,<br><br>You are right, the current optimization framework <br>focuses on manipulating the Transform parameters<br>without modifying the Model parameters.<br><br><br>One way to go about it, is for you to create a new<br>
type of Transform: T2 that is aware of both the<br>Transform and the Model.<br><br><br> T2 = { T1, Model }<br><br><br>and to make the parameters of T2 to be a concatenation<br>of the T1 parameters and the Model parameters.<br>
<br><br>Then use T2 as the transform of the registration.<br><br><br>You are strongly encouraged to contribute the T2<br>transform to the Insight Journal, in order to share<br>it with other ITK users.<br><br><br>Please let us know if you run into any difficulties<br>
while implementing T2.<br><br><br> Regards,<br><br><br> Luis<br><div class="gmail_quote"><br><br><br>------------------------------------------------------------------------<br>On Fri, Apr 23, 2010 at 12:08 PM, John Galeotti <span dir="ltr"><<a href="mailto:jgaleotti@cmu.edu">jgaleotti@cmu.edu</a>></span> wrote:<br>

<br>
I am interested in registering a group of ellipse spatial objects with roughly ellipsoidal structures in x-ray images. However, the software guide does not seem to provide a registration example in which the model parameters are adjusted by the optimizer.<br>
<br>
So, how do I go about splitting the optimization parameters between the transform and the model?<br>
<br>
Thank you,<br>
