Hi everyone!

I used VectorResampleImageFilter to resample vector images by ITK 4.12.  
And It isn’t working by ITK5.0.1. I’m trying with ResampleImageFilter to resample vector images. And I got error like that:  
DeformableRegistration.hxx:1500:3: error: no matching function for call to ‘itk::ResampleImageFilter\<itk::Image\<itk::Vector\<float, 3\>, 3\>, itk::Image\<itk::Vector\<float, 3\>, 3\>, double,double\>::SetInterpolator(itk::VectorLinearInterpolateNearestNeighborExtrapolateImageFunction\<itk::Image\<itk::Vector\<float, 3\>, 3\>, double\>::Pointer&)’ resample-\>SetInterpolator( vectorInterpolate );  
How i can fix that error?  
Thank you so much!

Please use the [NearestNeighborInterpolateImageFunction](https://itk.org/Doxygen/html/classitk_1_1NearestNeighborInterpolateImageFunction.html) instead of the `VectorLinearInterpolateNearestNeighborExtrapolateImageFunction`.

Thanks so much!=)) I changed all my code! and i got the next error. Do you have any ideas for me?  
DeformableRegistration.hxx:1134:5: error: no matching function for call to ‘itk::WarpVectorImageFilter\<itk::Image\<itk::Vector\<float, 3\>, 3\>, itk::Image\<itk::Vector\<float, 3\>, 3\>, itk::Image\<itk::Vector\<float, 3\>, 3\> \>::SetInterpolator(itk::NearestNeighborInterpolateImageFunction\<itk::Image\<itk::Vector\<float, 3\>, 3\>, double\>::Pointer)’  
m\_Warper-\>SetInterpolator( DefaultFieldInterpolatorType::New() );

Thanks!

Again the `ResampleImageFilter` should be used. Here is a commit where a couple examples were updated from the deprecated WarpImageFilter to using the powerful and flexible `ResampleImageFilter` with a `DisplacementFieldTransform`.

Maybe we should update the [migration guide](https://github.com/InsightSoftwareConsortium/ITK/blob/master/Documentation/ITK5MigrationGuide.md#class-changes) with a link to this commit which is quite instructive?

For clarification `WarpImageFilter` and `WarpVectorImageFilter` are not deprecated (yet), but the `ResampleImageFilter` can perform the same operation as it recommended to be used instead.

@dzenanz Working on a PR to improve the guide now.

Edited: some how I missed the word not before deprecated 🤦‍♂️

It means that `WarpImageFilter` and `WarpVectorImageFilter` are no longer used on ITK5. So, the best way is that I should replace `WarpImageFilter` and `WarpVectorImageFilter` with ResampleImageFilter?

That is correct.
