void GenerateData() override
itkGetMacro(Seed, IndexType)
To control overloaded versions of ComputeThreshold.
InputImageType::ConstPointer InputImageConstPointer
DataObjectPointer MakeOutput(unsigned int output)
ChainCodePathType::Pointer ChainCodePathPointer
~LevelTracingImageFilter() override=default
SmartPointer< const Self > ConstPointer
void GenerateInputRequestedRegion() override
Override since the filter needs all the data for the algorithm.
ChainCodePath< ImageDimension > ChainCodePathType
Simplified inverse ITK transforms.
ChainCodePathType::OffsetType OffsetType
OutputImageType::PixelType OutputImagePixelType
ImageToImageFilter< TInputImage, TOutputImage > Superclass
InputImageType::Pointer InputImagePointer
Trace a level curve/surface given a seed point on the level curve/surface.
OutputImageType::RegionType OutputImageRegionType
OutputImageType::Pointer OutputImagePointer
void PrintSelf(std::ostream &os, Indent indent) const override
InputImageType::PixelType InputImagePixelType
InputImageType::IndexType IndexType
virtual void Trace(const Dispatch< 2 > &)
itkTypeMacro(LevelTracingImageFilter, ImageToImageFilter)
ChainCodePathType * GetPathOutput()
Get the output as a ChainCodePath. This output is only generated in the 2D case.
itkStaticConstMacro(ImageDimension, unsigned int, TInputImage::ImageDimension)
itkSetMacro(Seed, IndexType)
Set/Get the seed.
void EnlargeOutputRequestedRegion(DataObject *output) override
Override since the filter produces the entire dataset.
InputImageType::RegionType InputImageRegionType
