#include <itkHuangThresholdCalculator.h>

Detailed Description

template<typename THistogram, typename 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.
