Detailed Description

template<typename TInputImage>
class itk::OtsuThresholdImageCalculator< TInputImage >

Computes the Otsu's threshold for an image.

This calculator computes the Otsu's threshold which separates an image into foreground and background components. The method relies on a histogram of image intensities. The basic idea is to maximize the between-class variance.

This class is templated over the input image type.

Warning
This method assumes that the input image consists of scalar pixel types.

Member Function Documentation

template<typename TInputImage >
void itk::OtsuThresholdImageCalculator< TInputImage >::Compute ( )

Compute the Otsu's threshold for the input image.

template<typename TInputImage >
virtual::itk::LightObject::Pointer itk::OtsuThresholdImageCalculator< TInputImage >::CreateAnother ( ) const
virtual

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::Object.

template<typename TInputImage >
virtual const char* itk::OtsuThresholdImageCalculator< TInputImage >::GetNameOfClass ( ) const
virtual

Run-time type information (and related methods).

Reimplemented from itk::Object.

template<typename TInputImage >
virtual SizeValueType itk::OtsuThresholdImageCalculator< TInputImage >::GetNumberOfHistogramBins ( ) const
virtual

Set/Get the number of histogram bins. Default is 128.

template<typename TInputImage >
virtual PixelType itk::OtsuThresholdImageCalculator< TInputImage >::GetThreshold ( ) const
virtual

Return the Otsu's threshold value.

template<typename TInputImage >
static Pointer itk::OtsuThresholdImageCalculator< TInputImage >::New ( )
static

Method for creation through the object factory.

template<typename TInputImage >
virtual void itk::OtsuThresholdImageCalculator< TInputImage >::PrintSelf ( std::ostream &  os,
Indent  indent 
) const
overrideprotectedvirtual

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::Object.

template<typename TInputImage >
virtual void itk::OtsuThresholdImageCalculator< TInputImage >::SetImage ( const ImageType _arg)
virtual

Set the input image.

template<typename TInputImage >
virtual void itk::OtsuThresholdImageCalculator< TInputImage >::SetNumberOfHistogramBins ( SizeValueType  _arg)
virtual

Set/Get the number of histogram bins. Default is 128.

template<typename TInputImage >
void itk::OtsuThresholdImageCalculator< TInputImage >::SetRegion ( const RegionType region)

Set the region over which the values will be computed
