Detailed Description

template<class TImage>
class itk::ThresholdImageFilter< TImage >

Set image values to a user-specified value if they are below, above, or between simple threshold values.

ThresholdImageFilter sets image values to a user-specified "outside" value (by default, "black") if the image values are below, above, or between simple threshold values.

The pixels must support the operators >= and <=.

Member Function Documentation

template<class TImage> virtual const char* itk::ThresholdImageFilter< TImage >::GetClassName (   )  const [virtual]

Run-time type information (and related methods). Reimplemented from itk::ImageToImageFilter< TImage, TImage >.

template<class TImage> virtual PixelType itk::ThresholdImageFilter< TImage >::GetOutsideValue (   )  [virtual]

Get the "outside" pixel value.

template<class TImage> Pointer itk::ThresholdImageFilter< TImage >::New (   )  [static]

Method for creation through the object factory. Reimplemented from itk::Object.

template<class TImage> void itk::ThresholdImageFilter< TImage >::PrintSelf (  std::ostream &  os, Indent  indent )  const [protected, virtual]

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from itk::ImageToImageFilter< TImage, TImage >.

template<class TImage> virtual void itk::ThresholdImageFilter< TImage >::SetOutsideValue (  PixelType  _arg  )  [virtual]

Set the "outside" pixel value. The default value NumericTraits<PixelType>::Zero.

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

ThresholdImageFilter 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< TImage >.

template<class TImage> void itk::ThresholdImageFilter< TImage >::ThresholdAbove (  const PixelType &  thresh  )

The values greater than or equal to the value are set to OutsideValue.

template<class TImage> void itk::ThresholdImageFilter< TImage >::ThresholdBelow (  const PixelType &  thresh  )

The values less than or equal to the value are set to OutsideValue.

template<class TImage> void itk::ThresholdImageFilter< TImage >::ThresholdOutside (  const PixelType &  lower, const PixelType &  upper )

The values outside the range are set to OutsideValue.
