<div>Hi Karthik,</div>
<div> </div>
<div>thanks for the help.</div>
<div> </div>
<div>Yeah, I did a multiresolution registration by subsampling the images.</div>
<div>The result is: my program runs faster than the one using itk multiresolution pyramid.</div>
<div>Much faster!</div>
<div>The subsampling process: subsampling->smoothing using gaussian filter.</div>
<div>The result is also correct, or I missed up some step ?</div>
<div> </div>
<div>Thank you.</div>
