Hi Cheng, <div>You could find an example of using Mattes MI metric using a TranslationTransform in </div><div>Examples/Registraion/ImageRegistration4.cxx.</div><div><br></div><div>The diagram of image registration framework is in Figure 8.8 of the software guide.</div>
<div> </div><div>Depends on how you design the regularization term, you might want to create a new transform or a new metric or a new interpolator.</div><div><br></div><div> itkMattesMutualInformationImageToImageMetric::GetValue() gives the value of the cost function, which covers both the Similarity and the Smoothing parts.</div>
<div><br></div><div>You can look into the code of itkImagreRegistrationMethod to fully understand the relationship among metric , optimizer, transforms and interpolators.</div><div><br></div><div>Hope this helps. </div><div>

And I want to add a new regularization term to the cost function. I think in the metric, there should be a "similarity" term and a "smoothing" term. If I can find the implementation code of these two term, I can just add my own regularization term behind. I notice that in the metric, there is a function "GetValue()". I'm wondering are both of the "similariy" and "smoothing" term calculated in this function? Which part of code is implementation for the "smoothing" term?</font><span class="HOEnZb"><font color="#888888"><br clear="all">
