In the ThinPlateSplineWarp.cxx a set of landmarks are read from the file LandmarkWarping3Landmarks1.txt which contains this:<br><br> 0 0 0 0 0 0<br>180 0 0 180 0 0<br>180 217 0 180 217 0<br>
0 217 0 0 217 0<br> 0 0 180 0 0 180<br>180 0 180 180 0 180<br>180 217 180 180 217 180<br> 0 217 180 0 217 180<br> 90 108 90 90 130 90<br><br><br><br>
As I understand these are 18 landmark points which is actually just deformation vectors. So the 3 first values in the third row:<br><br>180 217 0<br><br>corresponds to a vector at some location pointing 180 unit in the x-direction and 217 units in the y-direction.<br>
<br>But where in the image is this vector located?<br><br>Or are the above landmarks just 'regular' points that are interpolated by the ThinPlateSpline and not deformation vectors?<br><br><br>
