[Insight-users] MultiResolutionPyramidImageFilter: different behavior 32 bit vs 64 bit

[Maarten Beek]

Hi all,

The MultiResolutionPDEDeformableRegistration filter (with any of the PDEDeformableRegistrationFilter filters) uses the MultiResolutionPyramidImageFilter class to create image pyramids for the fixed and moving image. This MultiResolutionPyramidImageFilter class gives a warning about a kernel being truncated because it is growing too big when run on 64 bit system, while the warning doesn't appear when run on a 32 bit system (of course with the same values for the various parameters, like max error, variance).

Is this caused by the machine precision? How can I prevent this warning on a 64 bit machine?

Thanks - Maarten
