<div>Hi, Luis,</div>
<div> My input is just the Landmark of a heart vector field(I have deleted the part for reading the input image and get the deformed image in the ThinPlateSplineWarp.cxx,because I am not care about it), and the output is the deformation field.</div>
<div> I attach you the input file and the ThinPlateSplineWarp.cxx I used in my project. You will find that the Landmark have located the heart in a local region,so it doesn't have the problem "the landmarks are not located in space at the positions that you expect them to be with respect to the image."</div>
<div> In addition, I thought the TPS transform will tend to zero when the distance tend to infinity,because for 3D TPS, the sum of the wi*r will be wero smaller as the pixel is farther from the original Landmark. But I don't think it's true for the 2D TPS, because the sum of the wi*r^2*logr will be larger as the pixel is farther from the original Landmark. Is this a bug for the 2D TPS?</div>

<div>Thanks!</div>
