[Insight-users] Where I can find examples or paper about

[Luis Ibanez]

Hi Javier,



Please be more specific.

Our divinatory skills are quite limited and
tend to fade as we are rapidly aging.





When you say:



          "It does not work"



Do you mean:


1) It doesn't compile  ?
2) It compiles but does not link ?
3) It links but produces segmentation faults at run time ?
4) It throws exceptions at run time ?
5) It runs without crashing but the registration result
    does not aligns the images as expected  ?



We will be more than happy to help you, but we need your
help in providing enough information about your problem.




BTW, note that *ALL* the code shown in the software guide
is available in the directory Insight/Examples

In particular... the image registration examples are available
in


       Insight/Examples/Registration


You could happily go straight for the files:


       ImageRegistration14.cxx
       ImageRegistration15.cxx
       ImageRegistration16.cxx


where that metric is used.




These examples are compiled and executed every night in 55
different platforms ranging from cygwin, to Linux, to IRIX.

Regards,



     Luis
