Detailed Description

template<typename TInputImage, typename TOutputImage>
class itk::DenseFiniteDifferenceImageFilter< TInputImage, TOutputImage >

This filter implements a layer of the finite difference solver hierarchy that performs "dense" iteration, ie. iteration over all pixels in the input and output at each change calculation and update step. Dense iteration is in contrast to a "sparse" iteration over a subset of the pixels. See documentation for FiniteDifferenceImageFilter for an overview of the iterative finite difference algorithm:

$u_{\mathbf{i}}^{n+1}=u^n_{\mathbf{i}}+\Delta u^n_{\mathbf{i}}\Delta t$
The generic code for performing iterations and updates at each time step is inherited from the parent class. This class defines an update buffer for $ \Delta $ and the methods CalculateChange() and ApplyUpdate(). These methods are designed to automatically thread their execution. $ \Delta $ is defined as an image of identical size and type as the output image.
As we descend through each layer in the hierarchy, we know more and more about the specific application of our filter. At this level, we have committed to iteration over each pixel in an image. We take advantage of that knowledge to multithread the iteration and update methods.
Inputs and Outputs
This is an image to image filter. The specific types of the images are not fixed at this level in the hierarchy.
How to use this class
This filter is only one layer in a branch the finite difference solver hierarchy. It does not define the function used in the CalculateChange() and it does not define the stopping criteria (Halt method). To use this class, subclass it to a specific instance that supplies a function and Halt() method.

This callback method uses SplitUpdateContainer to acquire a region which it then passes to ThreadedCalculateChange for processing.

◆ CopyInputToOutput()

template<typename TInputImage, typename TOutputImage>
void itk::DenseFiniteDifferenceImageFilter< TInputImage, TOutputImage >::CopyInputToOutput ( )
overrideprotectedvirtual

A simple method to copy the data from the input to the output. ( Supports "read-only" image adaptors in the case where the input image type converts to a different output image type. )

Implements itk::FiniteDifferenceImageFilter< TInputImage, TOutputImage >.

◆ GetNameOfClass()

◆ GetUpdateBuffer()

template<typename TInputImage, typename TOutputImage>
virtual UpdateBufferType* itk::DenseFiniteDifferenceImageFilter< TInputImage, TOutputImage >::GetUpdateBuffer ( )
inlineprotectedvirtual

Method to allow subclasses to get direct access to the update buffer

◆ PrintSelf()

template<typename TInputImage, typename TOutputImage>
void itk::DenseFiniteDifferenceImageFilter< TInputImage, TOutputImage >::PrintSelf ( std::ostream &  os,
Indent  indent 
) const
overrideprotectedvirtual

In place operation can be turned on and off. Asking for in-place operation, i.e. calling SetInplace(true) or InplaceOn(), will be effective only if CanRunInPlace also returns true. By default CanRunInPlace checks whether the input and output image type match.

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

Reimplemented in itk::CurvatureFlowImageFilter< TInputImage, TOutputImage >, itk::AnisotropicDiffusionImageFilter< TInputImage, TOutputImage >, itk::MinMaxCurvatureFlowImageFilter< TInputImage, TOutputImage >, and itk::BinaryMinMaxCurvatureFlowImageFilter< TInputImage, TOutputImage >.

◆ ThreadedApplyUpdate()

template<typename TInputImage, typename TOutputImage>
virtual void itk::DenseFiniteDifferenceImageFilter< TInputImage, TOutputImage >::ThreadedApplyUpdate ( const TimeStepType dt,
const ThreadRegionType regionToProcess,
ThreadIdType  threadId 
)
protectedvirtual

Does the actual work of updating the output from the UpdateContainer over an output region supplied by the multithreading mechanism.

◆ ThreadedCalculateChange()

template<typename TInputImage, typename TOutputImage>
virtual TimeStepType itk::DenseFiniteDifferenceImageFilter< TInputImage, TOutputImage >::ThreadedCalculateChange ( const ThreadRegionType regionToProcess,
ThreadIdType  threadId 
)
protectedvirtual

Does the actual work of calculating change over a region supplied by the multithreading mechanism.

◆ ImageDimension

template<typename TInputImage, typename TOutputImage>
constexpr unsigned int itk::DenseFiniteDifferenceImageFilter< TInputImage, TOutputImage >::ImageDimension = Superclass::ImageDimension
staticconstexpr

Dimensionality of input and output data is assumed to be the same. It is inherited from the superclass.

◆ m_UpdateBuffer

template<typename TInputImage, typename TOutputImage>
UpdateBufferType::Pointer itk::DenseFiniteDifferenceImageFilter< TInputImage, TOutputImage >::m_UpdateBuffer
private

The buffer that holds the updates for an iteration of the algorithm.
