itk::GradientVectorFlowImageFilter< TInputImage, TOutputImage, TInternalPixel > Class Template Reference

#include <itkGradientVectorFlowImageFilter.h>

Detailed Description

template<typename TInputImage, typename TOutputImage, typename TInternalPixel = double>
class itk::GradientVectorFlowImageFilter< TInputImage, TOutputImage, TInternalPixel >

This class computes a diffusion of the gradient vectors for graylevel or binary edge map derive from the image. It enlarges the capture range of the gradient force and make external force derived from the gradient work effectively in the framework of deformable model.

This implementation of GVF closely follows this paper: http://ww.vavlab.ee.boun.edu.tr/courses/574/materialx/Active%20Contours/xu_GVF.pdf

dx and dy are assumed to be 1 and the CFL restriction for convergence has been modified for multi-dimensional images

GenerateData()

template<typename TInputImage , typename TOutputImage , typename TInternalPixel = double>

void itk::GradientVectorFlowImageFilter< TInputImage, TOutputImage, TInternalPixel >::GenerateData ( )

overrideprotectedvirtual

A version of GenerateData() specific for image processing filters. This implementation will split the processing across multiple threads. The buffer is allocated by this method. Then the BeforeThreadedGenerateData() method is called (if provided). Then, a series of threads are spawned each calling DynamicThreadedGenerateData(). After all the threads have completed processing, the AfterThreadedGenerateData() method is called (if provided). If an image processing filter cannot be threaded, the filter should provide an implementation of GenerateData(). That implementation is responsible for allocating the output buffer. If a filter can be threaded, it should NOT provide a GenerateData() method but should provide a DynamicThreadedGenerateData() instead.
