<DIV>Hi all,<BR>I'm using a multi-resolution Demons registration framework to
register two data sets. I use the filter implemented on GPU. It works fine;
however the it takes a long time to warp the moving image using the
displacement filter. My datasets are 2 64x64x64 (float) matrices, the whole
demons registration process takes less than a minute, but the warping step
takes about 10 minutes. <BR>Any ideas?</DIV>
