Detailed Description

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

Computes the RenyiEntropy's threshold for an image.

Kapur J.N., Sahoo P.K., and Wong A.K.C. (1985) "A New Method for Gray-Level Picture Thresholding Using the Entropy of the Histogram" Graphical Models and Image Processing, 29(3): 273-285 M. Emre Celebi 06.15.2007

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::RenyiEntropyThresholdCalculator< 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::RenyiEntropyThresholdCalculator< THistogram, TOutput >::GenerateData

void

)

This method causes the filter to generate its output.

Reimplemented from itk::ProcessObject.
