<html><body><div style="color:#000; background-color:#fff; font-family:times new roman, new york, times, serif;font-size:12pt"><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><div>Peymon<br></div></div></body></html>
