re[Insight-users] gistration binary images

[Luis Ibanez]

Hi Anne-Laure,

It will be very challenging to perform deformable registration on
binary images.

However, one possible method is to use


1) BSplineDeformableTransform
2) LBFGSB optimizer
3) MattesMutualInformation
4) NearestNeighbor interpolator


Note that your MattesMetric

1) Only needs *two bins* because your images are binary,

2) It will need a rather large number of samples, since
    the ribs will occupy a small fraction of the image
    volume.



   Regards,


       Luis
