Detailed Description

template<typename TInputImage, typename TRealType = float, typename TOutputImage = Image< TRealType, ::itk::GetImageDimension< TInputImage >::ImageDimension >>
class itk::DisplacementFieldJacobianDeterminantFilter< TInputImage, TRealType, TOutputImage >

Computes a scalar image from a vector image (e.g., deformation field) input, where each output scalar at each pixel is the Jacobian determinant of the vector field at that location. This calculation is correct in the case where the vector image is a "displacement" from the current location. The computation for the jacobian determinant is: det[ dT/dx ] = det[ I + du/dx ].

Overview

This filter is based on itkVectorGradientMagnitudeImageFilter and supports the m_DerivativeWeights weights for partial derivatives.

Note that the determinant of a zero vector field is also zero, whereas the Jacobian determinant of the corresponding identity warp transformation is 1.0. In order to compute the effective deformation Jacobian determinant 1.0 must be added to the diagonal elements of Jacobian prior to taking the derivative. i.e. det([ (1.0+dx/dx) dx/dy dx/dz ; dy/dx (1.0+dy/dy) dy/dz; dz/dx dz/dy (1.0+dz/dz) ])

Template Parameters (Input and Output)

This filter has one required template parameter which defines the input image type. The pixel type of the input image is assumed to be a vector (e.g., itk::Vector, itk::RGBPixel, itk::FixedArray). The scalar type of the vector components must be castable to floating point. Instantiating with an image of RGBPixel<unsigned short>, for example, is allowed, but the filter will convert it to an image of Vector<float,3> for processing.

The second template parameter, TRealType, can be optionally specified to define the scalar numerical type used in calculations. This is the component type of the output image, which will be of itk::Vector<TRealType, N>, where N is the number of channels in the multiple component input image. The default type of TRealType is float. For extra precision, you may safely change this parameter to double.

The third template parameter is the output image type. The third parameter will be automatically constructed from the first and second parameters, so it is not necessary (or advisable) to set this parameter explicitly. Given an M-channel input image with dimensionality N, and a numerical type specified as TRealType, the output image will be of type itk::Image<TRealType, N>.

Filter Parameters

The method SetUseImageSpacingOn will cause derivatives in the image to be scaled (inversely) with the pixel size of the input image, effectively taking derivatives in world coordinates (versus isotropic image space). SetUseImageSpacingOff turns this functionality off. Default is UseImageSpacingOn. The parameter UseImageSpacing can be set directly with the method SetUseImageSpacing(bool).

Weights can be applied to the derivatives directly using the SetDerivativeWeights method. Note that if UseImageSpacing is set to TRUE (ON), then these weights will be overridden by weights derived from the image spacing when the filter is updated. The argument to this method is a C array of TRealValue type.

Constraints

We use vnl_det for determinent computation, which only supports square matrices. So the vector dimension of the input image values must be equal to the image dimensions, which is trivially true for a deformation field that maps an n-dimensional space onto itself.

Currently, dimensions up to and including 4 are supported. This limitation comes from the presence of vnl_det() functions for matrices of dimension up to 4x4.

The template parameter TRealType must be floating point (float or double) or a user-defined "real" numerical type with arithmetic operations defined sufficient to compute derivatives.

virtual

DisplacementFieldJacobianDeterminantFilter needs a larger input requested region than the output requested region (larger by the kernel size to calculate derivatives). As such, DisplacementFieldJacobianDeterminantFilter needs to provide an implementation for GenerateInputRequestedRegion() in order to inform the pipeline execution model.

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

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

void itk::DisplacementFieldJacobianDeterminantFilter< TInputImage, TRealType, TOutputImage >::SetDerivativeWeights

(

const WeightsType &

)

Directly Set/Get the array of weights used in the gradient calculations. Note that calling UseImageSpacingOn will clobber these values.

virtual void itk::DisplacementFieldJacobianDeterminantFilter< TInputImage, TRealType, TOutputImage >::SetNeighborhoodRadius ( RadiusType  _arg )

protectedvirtual

Get/Set the neighborhood radius used for gradient computation

void itk::DisplacementFieldJacobianDeterminantFilter< TInputImage, TRealType, TOutputImage >::SetUseImageSpacing

(

bool

)

Set/Get whether or not the filter will use the spacing of the input image in its calculations

void itk::DisplacementFieldJacobianDeterminantFilter< TInputImage, TRealType, TOutputImage >::SetUseImageSpacingOff ( )

inline

Reset the derivative weights to ignore image spacing. Use this option if you want to calculate the Jacobian determinant in the image space. Default is ImageSpacingOn.

void itk::DisplacementFieldJacobianDeterminantFilter< TInputImage, TRealType, TOutputImage >::SetUseImageSpacingOn ( )

inline

Set the derivative weights according to the spacing of the input image (1/spacing). Use this option if you want to calculate the Jacobian determinant in the space in which the data was acquired. Default is ImageSpacingOn.

void itk::DisplacementFieldJacobianDeterminantFilter< TInputImage, TRealType, TOutputImage >::ThreadedGenerateData ( const OutputImageRegionType &  outputRegionForThread, ThreadIdType  threadId  )

protectedvirtual

DisplacementFieldJacobianDeterminantFilter can be implemented as a multithreaded filter (we're only using vnl_det(), which is trivially thread safe). Therefore, this implementation provides a ThreadedGenerateData() routine which is called for each processing thread. The output image data is allocated automatically by the superclass prior to calling ThreadedGenerateData(). ThreadedGenerateData can only write to the portion of the output image specified by the parameter "outputRegionForThread"
