If something like this happens ：Too many samples map outside  moving image buffer: 13840 / 1722508

The mistake is ： It indicates that the difference between the two images before registration is too large , As for what is the gap ？ I think size and spacing,dierect Can be ignored , Here's a look at origin The gap between ;

remarks ： During my experiment ,size and spacing, The directions are different before registration , So I think it should be origin The problem of

So with itkChangeInformationImageFilter ： hold fixed and moving Of two images origin Set it up , Specifically, put moving Of origin Set to fixed Of origin

Here are some examples to refer to ;】

Finally, the above example can be used for registration ; This is the result of my two data sets , yes WarpImageFilter The filtered result , The effect is good ,
