Detailed Description

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

Computes the Intermodes's threshold for an image.

J. M. S. Prewitt and M. L. Mendelsohn, "The analysis of cell images," in Annals of the New York Academy of Sciences, vol. 128, pp. 1035-1053, 1966. * Assumes a bimodal histogram. The histogram needs is smoothed (using a running average of size 3, iteratively) until there are only two local maxima. j and k Threshold t is (j+k)/2. Images with histograms having extremely unequal peaks or a broad and flat valley are unsuitable for this method.

This class is templated over the input histogram type.

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

virtual::itk::LightObject::Pointer itk::IntermodesThresholdCalculator< 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::IntermodesThresholdCalculator< THistogram, TOutput >::GenerateData ( void  ) [protected, virtual]

This method causes the filter to generate its output.

Reimplemented from itk::ProcessObject.

Run-time type information (and related methods).

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

template<class THistogram , class TOutput = double>
virtual bool itk::IntermodesThresholdCalculator< THistogram, TOutput >::GetUseInterMode ( ) const [virtual]

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

Method for creation through the object factory.

template<class THistogram , class TOutput = double>
void itk::IntermodesThresholdCalculator< THistogram, TOutput >::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::ProcessObject.
