[ITK-users] MutualInformationImageToImageMetric without transformation

When the program crashes, no error appears?

Take also into account, that having the same size does not mean always that
they overlap. You have to check also their origin and spacing in case they
have different physical locations.

Regarding the standard deviation issue, if you previously normalize the
image, then a standard deviation of 0.4 works, please see this example:
