[Insight-users] MattMutualInformationImageToImageMetricv4 + BSplineTransform

[Sureerat Reaungamornrat]

Dear Sepehri,

     I simplified the code from http://stnava.github.io/ANTs/ such that the
only metric is MattesMI and the only transform is B-Spline.
The attached files are the source code and the 2D data set to run it. I am
still learning v4 so I might make wrong choices in the
parameter setting.

Thank you very much,

Sureerat
