#include <itkCurvatureFlowImageFilter.h>

Detailed Description

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

Denoise an image using curvature driven flow.

CurvatureFlowImageFilter implements a curvature driven image denoising algorithm. Iso-brightness contours in the grayscale input image are viewed as a level set. The level set is then evolved using a curvature-based speed function:

\[ I_t = \kappa |\nabla I| \]

where \( \kappa \) is the curvature.

The advantage of this approach is that sharp boundaries are preserved with smoothing occurring only within a region. However, it should be noted that continuous application of this scheme will result in the eventual removal of all information as each contour shrinks to zero and disappear.

Note that unlike level set segmentation algorithms, the image to be denoised is already the level set and can be set directly as the input using the SetInput() method.

This filter has two parameters: the number of update iterations to be performed and the timestep between each update.

The timestep should be "small enough" to ensure numerical stability. Stability is guarantee when the timestep meets the CFL (Courant-Friedrichs-Levy) condition. Broadly speaking, this condition ensures that each contour does not move more than one grid position at each timestep. In the literature, the timestep is typically user specified and have to manually tuned to the application.

This filter make use of the multi-threaded finite difference solver hierarchy. Updates are computed using a CurvatureFlowFunction object. A zero flux Neumann boundary condition when computing derivatives near the data boundary.

This filter may be streamed. To support streaming this filter produces a padded output which takes into account edge effects. The size of the padding is m_NumberOfIterations on each edge. Users of this filter should only make use of the center valid central region.

Warning
This filter assumes that the input and output types have the same dimensions. This filter also requires that the output image pixels are of a floating point type. This filter works for any dimensional images.

◆ EnlargeOutputRequestedRegion()

template<typename TInputImage , typename TOutputImage >
void itk::CurvatureFlowImageFilter< TInputImage, TOutputImage >::EnlargeOutputRequestedRegion ( DataObject )
overrideprotectedvirtual

To support streaming, this filter produces a output which is larger than the original requested region. The output is padding by m_NumberOfIterations pixels on edge.

Reimplemented from itk::ProcessObject.

◆ GenerateInputRequestedRegion()

template<typename TInputImage , typename TOutputImage >
void itk::CurvatureFlowImageFilter< TInputImage, TOutputImage >::GenerateInputRequestedRegion ( )
overrideprotectedvirtual

Edge effects are taken care of by padding the output requested region. As such, the input requested region needs to at minimum the same size as the output requested region.

Get the timestep parameter.

◆ Halt()

template<typename TInputImage , typename TOutputImage >
bool itk::CurvatureFlowImageFilter< TInputImage, TOutputImage >::Halt ( )
inlineoverrideprotectedvirtual

Supplies the halting criteria for this class of filters. The algorithm will stop after a user-specified number of iterations.

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

◆ InitializeIteration()

template<typename TInputImage , typename TOutputImage >
void itk::CurvatureFlowImageFilter< TInputImage, TOutputImage >::InitializeIteration ( )
overrideprotectedvirtual

Initialize the state of filter and equation before each iteration. Progress feedback is implemented as part of this method.
