<DIV><FONT face=Arial size=2>Hi,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I'm trying to run the DeformableRegistration4.cxx
example which uses B-Splines for non-rigid registration. My goal is to
eventually replace the means squares metric in this example with a MI metric.
However before that, I'm just simply running a slightly modified version of the
example first to take in a 3D volume (200x200x200) instead of a 2D slice. After
running for 2+ hours, this is all I get:</FONT></DIV>

0.835 1.500<BR></FONT></DIV>
<DIV><FONT face=Arial size=2>With a maximum iteration number at 1000, this
process is going to take quite a few days to complete. I'm running this on a
Pentium 1.6M with 1GB RAM. Just wanted to do a sanity check to see if this
sounds normal. If not, what kind of worst case running times should I be
expecting on a 3D volume of size 200x200x200?</FONT></DIV>

<DIV><FONT face=Arial size=2>Cheers,</FONT></DIV>
