[Insight-users] test image for DeformableRegistration7.cxx and DeformableRegistration8.cxx

[Luis Ibanez]

Hi Xavier,

I missed to notice that these two examples are 3D,
instead of 2D.  Sorry about that.


They will not run correctly by providing 2D images
as input. You may want to create a deformed 3D image
to be used as input.

In this way you can use your favorite 3D image as the
FixedImage input, and its artificial deformation as
the MovingImage input.


In order to create deformations in 3D images you can
use any of the examples:


     Insight/Examples/Registration/
                         LandmarkWarping2.cxx
                         BSplineWarping1.cxx


You will only need to modify the code in order to
replace Dimension = 2, with Dimension = 3.

You will find easier to do the deformation with
LandmarkWarping2 than with BSplineWarping1.

The input file that you need to provide to Landmark
Warping is a plain text file that should contain the
coordinates of landmarks in the fixed image and their
corresponding coordinates in the moving image.

For example, if you have landmarks:

   FixedImage       MovingImage
    (0,0,0)   ----->  (0,0,0)
   (100,0,0)  ----->(110,0,0)
   (0,100,0)  -----> (0,150,0)
    (0,0,30)   ----->  (0,0,40)


then the input file with landmark coordinates information
should be:

    0   0   0             0   0   0
  100   0   0           110   0   0
    0 100   0             0 150   0
    0   0  30             0   0  40



Another easy way of generating a deformed image is to use
the LandmarkWarping plugin for VolView.
