Detailed Description

Applies a sinc interpolation to a given image. You must specify an output extent greater than the original image to get the interpolated result. The algorithm follows the following steps:

Run svkMriImageFFT on the input volume. Move k=0 to the center of the volume. Use svkMriZeroFill to pad the kspace volume. Move k=0 back to the origin. Run svkMriImageFFT to reverse the FFT.

int FillInputPortInformation ( int  port, vtkInformation *  info  )

protectedvirtual

Defines the input type: svkMriImageData.

svkImageData * GetOutput

(

)

This is only overriden to prevent it from being hidden. When you override a method you need to override every overloaded version.

svkImageData * GetOutput

(

int

port

)

We want to override this method so that we can return a pointer to the input in the case of an in place operation.
