I am wondering what is the difference? DeformationField is basically a vectorial image isn't it? Since there have been classes in ITK to do multiResolution image registration (for scalar) and as a part of that one needs to apply the same
pyramid on deformation field (VectorResampleImageFilter), I thought it is very natural to have this class imeplemented for vectorial image pyramid. Please illustrate me if I am missing something in my induction. Does it have anything to do with difference between covector and vector image (I am sorry if it is irrelevant)?<br><br>Thanks,<br><br></div><div style="font-family: times new roman,new york,times,serif; font-size: 14pt;"><br><div style="font-family: arial,helvetica,sans-serif; font-size: 13px;"><font size="2" face="Tahoma"><hr size="1"><b><span style="font-weight: bold;">From:</span></b> Luis Ibanez <luis.ibanez@kitware.com><br><b><span style="font-weight: bold;">To:</span></b> Kaveh Kohan <kaveh.kohan@yahoo.com><br><b><span style="font-weight: bold;">Cc:</span></b> insight-users@itk.org<br><b><span style="font-weight: bold;">Sent:</span></b> Mon, October 12, 2009 12:41:57 PM<br><b><span style="font-weight: bold;">Subject:</span></b>
Re: [Insight-users] Question about multiResolutionPyramidImageFilter class<br></font><br>
Hi Kaveh,<br><br>Unfortunately,<br>I think that the answer to both question is : no.<br><br>On the bright side, however, there have been some efforts<br>for extending the Image Registration Framework to support<br>vector images.<br><br>The major components to be modified are the Image metrics.<br>A couple of Vector Image interpolators are already available,<br>and the other components (Optimizer, Transform) are image<br>agnostic.<br><br>See for example:<br><span><a target="_blank" href="http://svn.na-mic.org/NAMICSandBox/trunk/VectorImageRegistrationMethod/">http://svn.na-mic.org/NAMICSandBox/trunk/VectorImageRegistrationMethod/</a></span><br><br><br>You may want to join these efforts.<br><br><br> Regards,<br><br><br> Luis<br><br><br><br>--------------------------------------------------------------------------<br>On Sat, Oct 10, 2009 at 6:38 PM, Kaveh Kohan <<a
