<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">Hi, all -<br><br> I have a simple question here -<br><br>I'd like to perform point based image registration by using least square approach (basically finding the rotation matrix by using singular value decomposition SVD). Inputs are two sets of corresponding points, and I just need to get the transformation matrix back. <br><br>More like the functions in Examples\Patened\ICP*.cxx, but use closed form instead of iterative approach. What is the ITK filter to perform this?<br><br> Thanks a lot in advance.<br><br>Suyang<br></td></tr></table><br>
