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.

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.
