Detailed Description

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

Computes the Li threshold for an image. Aka intermeans.

Implements Li's Minimum Cross Entropy thresholding method This implementation is based on the iterative version (Ref. 2) of the algorithm. 1) Li C.H. and Lee C.K. (1993) "Minimum Cross Entropy Thresholding" Pattern Recognition, 26(4): 617-625 2) Li C.H. and Tam P.K.S. (1998) "An Iterative Algorithm for Minimum Cross Entropy Thresholding"Pattern Recognition Letters, 18(8): 771-776 3) Sezgin M. and Sankur B. (2004) "Survey over Image Thresholding Techniques and Quantitative Performance Evaluation" Journal of Electronic Imaging, 13(1): 146-165 http://citeseer.ist.psu.edu/sezgin04survey.html

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::LiThresholdCalculator< 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 >.

void itk::LiThresholdCalculator< THistogram, TOutput >::GenerateData

(

)

[protected, virtual]

This method causes the filter to generate its output.

Reimplemented from itk::ProcessObject.

[static]

Method for creation through the object factory.
