[Insight-users] Thin Plate Splines Registration

[Bill Lorensen]

Change the typedef PixelType to short.  The ImageFileReader is
converting the input data to unsigned char.

> I would like to register 3D CT images of the abdomen using the Thin Plate
> Splines Registration.
> My goal is to select a set of landmarks (6 or 7 for instance) both in a
> FixedImage and MovingImage, compute the transform from the MovingImage to
> the FixedImage, and apply this transform to the MovingImage (and finally
> save the RegisteredMovingImage as a ".mha" file).

> Actually, I already tried to implement such a process based on the
> "InsightToolkit-3.14.0/Examples/Registration/ThinPlateSplineWarp.cxx".
> The problem is that my output moving registered image presents intensities
> between 0 and 255, as it had been rescaled on 8 bits, whereas both my input
> images had intensities between lets say -1000 and +2000.
> Where does this come from?
> Is it possible to avoid this?
>
> Thank you very much in advance for your help.

> Best regards.
