Detailed Description

template<class THistogram, class TOutput = double>
class itk::HuangThresholdCalculator< THistogram, TOutput >

Computes the Huang's threshold for an image.

This calculator computes the Huang's fuzzy threshold which separates an image into foreground and background components. Uses Shannon's entropy function (one can also use Yager's entropy function) Huang L.-K. and Wang M.-J.J. (1995) "Image Thresholding by Minimizing the Measures of Fuzziness" Pattern Recognition, 28(1): 41-51 Reimplemented (to handle 16-bit efficiently) by Johannes Schindelin Jan 31, 2011

This class is templated over the input histogram type.

Warning:
This calculator assumes that the input histogram has only one dimension.

Member Function Documentation

template<class THistogram , class TOutput = double>
virtual::itk::LightObject::Pointer itk::HuangThresholdCalculator< THistogram, TOutput >::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::HistogramThresholdCalculator< THistogram, TOutput >.

template<class THistogram , class TOutput = double>
void itk::HuangThresholdCalculator< THistogram, TOutput >::GenerateData ( void  ) [protected, virtual]

This method causes the filter to generate its output.

Reimplemented from itk::ProcessObject.

template<class THistogram , class TOutput = double>
virtual const char* itk::HuangThresholdCalculator< THistogram, TOutput >::GetNameOfClass ( ) const [virtual]

Run-time type information (and related methods).

Reimplemented from itk::HistogramThresholdCalculator< THistogram, TOutput >.

template<class THistogram , class TOutput = double>
static Pointer itk::HuangThresholdCalculator< THistogram, TOutput >::New ( ) [static]

Method for creation through the object factory.

Reimplemented from itk::HistogramThresholdCalculator< THistogram, TOutput >.

template<class THistogram , class TOutput = double>
void itk::HuangThresholdCalculator< THistogram, TOutput >::operator= ( const Self &  ) [private]

Time when GenerateOutputInformation was last called.

Reimplemented from itk::HistogramThresholdCalculator< THistogram, TOutput >.
