<DIV style="FONT-SIZE: 12pt; FONT-FAMILY: times new roman, new york, times, serif">
<DIV>I am trying to modify the 3D rigid registration (as given in Examples, ImageRegistration8) to use Mutual information. I have tried changing the </DIV>
<DIV>itkMeanSquaresImageToImageMetric.h include </DIV>
<DIV>and </DIV>
<DIV>typedef itk::MeanSquaresImageToImageMetric< <BR> FixedImageType, <BR> MovingImageType > MetricType;</DIV>
<DIV>to both MattesMutualInformation and MutualInformation,</DIV>
<DIV>and the code builds, but seems to give wrong results. In one test case, the MattesMutual will not even do one iteration, just reports a fit (where the two images aren't registered)</DIV>
<DIV> Anone know why this is?</DIV>
