Detailed Description

template<class TInputImage, class TOutputImage>
class itk::MirrorPadImageFilter< TInputImage, TOutputImage >

Increase the image size by padding with replicants of the input image value.

MirrorPadImageFilter changes the image bounds of an image. Any added pixels are filled in with a wrapped replica of the input image. The image bounds of the output must be specified.

This filter is implemented as a multithreaded filter. It provides a ThreadedGenerateData() method for its implementation.

Member Function Documentation

template<class TInputImage, class TOutputImage> int itk::MirrorPadImageFilter< TInputImage, TOutputImage >::BuildInterRegions (  std::vector< long > &  inputRegionStart, std::vector< long > &  outputRegionStart, std::vector< long > &  inputRegionSizes, std::vector< long > &  outputRegionSizes, long  inputIndex, long  outputIndex, long  inputSize, long  outputSize, int  numRegs, int &  regCtr )  [protected]

Generate region 0 (inter-region) information. Based on the indices of the input and the output for this dimension, decide what are the starting points and the lengths of the output region directly corresponding to the input region. Padding will be on either side of this region. The algorithmic complications are necessary to support the streaming interface and multithreading.

template<class TInputImage, class TOutputImage> int itk::MirrorPadImageFilter< TInputImage, TOutputImage >::BuildPostRegions (  std::vector< long > &  inputRegionStart, std::vector< long > &  outputRegionStart, std::vector< long > &  inputRegionSizes, std::vector< long > &  outputRegionSizes, long  inputIndex, long  outputIndex, long  inputSize, long  outputSize, int  numRegs, int &  regCtr )  [protected]

Generate region 2 (post-region) information. Based on the indices of the input and the output for this dimension, decide what are the starting points and the lengths of the output region directly succeeding the input region in this dimension. This may require more than one region be defined if the padding is larger than the size of the input image in this dimension. Other algorithmic complications are necessary to support the streaming interface and multithreading.

template<class TInputImage, class TOutputImage> int itk::MirrorPadImageFilter< TInputImage, TOutputImage >::BuildPreRegions (  std::vector< long > &  inputRegionStart, std::vector< long > &  outputRegionStart, std::vector< long > &  inputRegionSizes, std::vector< long > &  outputRegionSizes, long  inputIndex, long  outputIndex, long  inputSize, long  outputSize, int  numRegs, int &  regCtr )  [protected]

Generate region 1 (pre-region) information. Based on the indices of the input and the output for this dimension, decide what are the starting points and the lengths of the output region directly preceding the input region in this dimension. This may require more than one region be defined if the padding is larger than the size of the input image in this dimension. Other algorithmic complications are necessary to support the streaming interface and multithreading.

template<class TInputImage, class TOutputImage> void itk::MirrorPadImageFilter< TInputImage, TOutputImage >::ConvertOutputIndexToInputIndex (  OutputImageIndexType &  outputIndex, InputImageIndexType &  inputIndex, OutputImageRegionType &  outputRegion, InputImageRegionType &  inputRegion, int  oddRegionArray[ImageDimension] )  [protected]

Convert from the output index to the input index taking into consideration mirrored and normal regions.

template<class TInputImage, class TOutputImage> int itk::MirrorPadImageFilter< TInputImage, TOutputImage >::FindRegionsInArea (  long  start, long  end, long  size, long  offset )  [protected]

Given the start and end indices of a region, determine how many instances of size fit within the region. The variable offset provides a way to adjust width of the area while forcing alignment to the start or end location.

template<class TInputImage, class TOutputImage> virtual void itk::MirrorPadImageFilter< TInputImage, TOutputImage >::GenerateInputRequestedRegion (   )  [protected, virtual]

MirrorPadImageFilter needs a different input requested region than output requested region. As such, MirrorPadImageFilter needs to provide an implementation for GenerateInputRequestedRegion() in order to inform the pipeline execution model. See also: ProcessObject::GenerateInputRequestedRegion() PadImageFilter::GenerateInputRequestedRegion() Reimplemented from itk::PadImageFilter< TInputImage, TOutputImage >.

template<class TInputImage, class TOutputImage> int itk::MirrorPadImageFilter< TInputImage, TOutputImage >::GenerateNextInputRegion (  long *  regIndices, long *  regLimit, std::vector< long >  indices[ImageDimension], std::vector< long >  sizes[ImageDimension], InputImageRegionType &  outputRegion )  [protected]

Given an n dimensional list of input region breakpoints in indices and size (where the current region and maximum region for each dimension is encoded in regIndices and regLimit), choose the next input region.

template<class TInputImage, class TOutputImage> int itk::MirrorPadImageFilter< TInputImage, TOutputImage >::GenerateNextOutputRegion (  long *  regIndices, long *  regLimit, std::vector< long >  indices[ImageDimension], std::vector< long >  sizes[ImageDimension], OutputImageRegionType &  outputRegion )  [protected]

Given an n dimensional list of output region breakpoints in indices and size (where the current region and maximum region for each dimension is encoded in regIndices and regLimit), choose the next output region.

template<class TInputImage, class TOutputImage> virtual const char* itk::MirrorPadImageFilter< TInputImage, TOutputImage >::GetClassName (   )  const [virtual]

Run-time type information (and related methods). Reimplemented from itk::PadImageFilter< TInputImage, TOutputImage >.

template<class TInputImage, class TOutputImage> itk::MirrorPadImageFilter< TInputImage, TOutputImage >::itkStaticConstMacro (  ImageDimension  , unsigned  int, TInputImage::ImageDimension  )

ImageDimension enumeration. Reimplemented from itk::PadImageFilter< TInputImage, TOutputImage >.

template<class TInputImage, class TOutputImage> Pointer itk::MirrorPadImageFilter< TInputImage, TOutputImage >::New (   )  [static]

Method for creation through the object factory. Reimplemented from itk::PadImageFilter< TInputImage, TOutputImage >.

template<class TInputImage, class TOutputImage> int itk::MirrorPadImageFilter< TInputImage, TOutputImage >::RegionIsOdd (  long  base, long  test, long  size )  [protected]

Decide whether test falls within an odd or even number of size regions from base.

template<class TInputImage, class TOutputImage> void itk::MirrorPadImageFilter< TInputImage, TOutputImage >::ThreadedGenerateData (  const OutputImageRegionType &  outputRegionForThread, int  threadId )  [protected, virtual]

MirrorPadImageFilter can be implemented as a multithreaded filter. 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" See also: ImageToImageFilter::ThreadedGenerateData(), ImageToImageFilter::GenerateData() Reimplemented from itk::ImageSource< TOutputImage >.
