[Insight-users] ImageRegistration4

[Ganesh Narayanasamy]

I converted the ImageRegistration4.cxx on MattesMutualInformation technique from 2D into 3D by changing line #123 from 2 to 3:
const    unsigned int    Dimension = 3;

Is that all that needs to be done?
When I did Build Solution and ran the executable with 2 input images and a name for an output image, I got this error message:


****

Can you identify the error and let me know any corrective step?
Thanks for your help,

Ganesh
