itk::WarpImageFilter< TInputImage, TOutputImage, TDisplacementField > Class Template Reference

#include <itkWarpImageFilter.h>

Detailed Description

template<typename TInputImage, typename TOutputImage, typename TDisplacementField>
class itk::WarpImageFilter< TInputImage, TOutputImage, TDisplacementField >

Warps an image using an input displacement field.

WarpImageFilter warps an existing image with respect to a given displacement field.

A displacement field is represented as a image whose pixel type is some vector type with at least N elements, where N is the dimension of the input image. The vector type must support element access via operator [].

The output image is produced by inverse mapping: the output pixels are mapped back onto the input image. This scheme avoids the creation of any holes and overlaps in the output image.

Each vector in the displacement field represent the distance between a geometric point in the input space and a point in the output space such that:

\[ p_{in} = p_{out} + d \]

Typically the mapped position does not correspond to an integer pixel position in the input image. Interpolation via an image function is used to compute values at non-integer positions. The default interpolation typed used is the LinearInterpolateImageFunction. The user can specify a particular interpolation function via SetInterpolator(). Note that the input interpolator must derive from base class InterpolateImageFunction.

Position mapped to outside of the input image buffer are assigned a edge padding value.

The LargestPossibleRegion for the output is inherited from the input displacement field. The output image spacing, origin and orientation may be set via SetOutputSpacing, SetOutputOrigin and SetOutputDirection. The default are respectively a vector of 1's, a vector of 0's and an identity matrix.

This class is templated over the type of the input image, the type of the output image and the type of the displacement field.

The input image is set via SetInput. The input displacement field is set via SetDisplacementField.

This filter is implemented as a multithreaded filter.

Warning

This filter assumes that the input type, output type and displacement field type all have the same number of dimensions.

WarpImageFilter is implemented as a multi-threaded filter. As such, it needs to provide and implementation for DynamicThreadedGenerateData().

Reimplemented from itk::ImageSource< TOutputImage >.

EvaluateDisplacementAtPhysicalPoint() [1/2]

template<typename TInputImage , typename TOutputImage , typename TDisplacementField >

void itk::WarpImageFilter< TInputImage, TOutputImage, TDisplacementField >::EvaluateDisplacementAtPhysicalPoint ( const PointType &  point, const DisplacementFieldType *  fieldPtr, DisplacementType &  output  )

protected

This function should be in an interpolator but none of the ITK interpolators at this point handle edge conditions properly

EvaluateDisplacementAtPhysicalPoint() [2/2]

template<typename TInputImage , typename TOutputImage , typename TDisplacementField >

void itk::WarpImageFilter< TInputImage, TOutputImage, TDisplacementField >::EvaluateDisplacementAtPhysicalPoint ( const PointType &  point, DisplacementType &  output  )

protected

This function should be in an interpolator but none of the ITK interpolators at this point handle edge conditions properly

If this method is called in a loop, the EvaluateDisplacementAtPhysicalPoint(const PointType &, const DisplacementFieldType *, DisplacementType &) overload will offer better performance. The displacement field can be obtained using the GetDisplacementField() method

GenerateInputRequestedRegion()

template<typename TInputImage , typename TOutputImage , typename TDisplacementField >

void itk::WarpImageFilter< TInputImage, TOutputImage, TDisplacementField >::GenerateInputRequestedRegion ( )

overridevirtual

It is difficult to compute in advance the input image region required to compute the requested output region. Thus the safest thing to do is to request for the whole input image.

For the displacement field, the input requested region set to be the same as that of the output requested region.

Reimplemented from itk::ImageToImageFilter< TInputImage, TOutputImage >.

GenerateOutputInformation()

template<typename TInputImage , typename TOutputImage , typename TDisplacementField >

void itk::WarpImageFilter< TInputImage, TOutputImage, TDisplacementField >::GenerateOutputInformation ( )

overridevirtual

WarpImageFilter produces an image which is a different size than its input image. As such, it needs to provide an implementation for GenerateOutputInformation() which set the output information according the OutputSpacing, OutputOrigin and the displacement field's LargestPossibleRegion.

Reimplemented from itk::ProcessObject.
