<DIV><FONT face=Arial>Hi ITKUsers,</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>I do not fully understand the meaning of the following
sentences about the number of the control points of BSpline.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>// Since we are using a BSpline of order 3, the
coverage of the BSpling grid<BR>// should exceed by one the spatial extent
of the image on the lower region of<BR>// image indices, and by two grid
points on the upper region of image indices.<BR></FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>In my opinion, if the internal grid can just cover the
full image, we only need exceed by one grid instead of two on the upper region
of image indices.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Hope your confirmation!</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Regards,</FONT></DIV>
