Detailed Description

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

Computes the Triangle's threshold for an image.

This calculator computes the Triangle's threshold which separates an image into foreground and background components. The method relies on a histogram of image intensities. A line is drawn between the peak point in the hist and the furthest zero point (robustly estimated as the 1% or 99% point). The threshold is the position of maximum difference between the line and the original histogram.

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::TriangleThresholdCalculator< 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::TriangleThresholdCalculator< 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::TriangleThresholdCalculator< 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::TriangleThresholdCalculator< 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::TriangleThresholdCalculator< THistogram, TOutput >::operator= ( const Self ) [private]

Time when GenerateOutputInformation was last called.
