Detailed Description

template<class 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.

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

Compute the Otsu's threshold for the input image.

template<class TInputImage >

virtual::itk::LightObject::Pointer itk::OtsuThresholdImageCalculator< TInputImage >::CreateAnother ( void ) 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<class TInputImage >

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

virtual

Run-time type information (and related methods).

Reimplemented from itk::Object.

template<class TInputImage >

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

virtual

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

template<class TInputImage >

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

virtual

Return the Otsu's threshold value.

virtual

Set the input image.
