[Insight-users] Saving BSplineDeformableTransformed image

[Luis Ibanez]

Hi Lars,


0) One hour for resampling an image sounds excesive.
    Are you compiling for "Release" ?


1) What interpolator are you using ?
    The interpolator is the critical component of the
    resampling process.


2) BTW, Registering two images in 3D using BSpline Deformable
    Transform in just 5min sounds too good to be true.   :-/

    Do you have any evidence supporting your assumption that
    the registration has actually succeded in 5 minutes ?


3) Please post your code to the list....


    Thanks



        Luis
