Detailed Description

template<class TInputHistogram>
class itk::OtsuMultipleThresholdsCalculator< TInputHistogram >

Computes Otsu's thresholds for a histogram.

You plug in the target histogram using SetInputHistogram method and specify the number of thresholds you want to be computed. Then call the GenerateData method to run the alogithm.

The thresholds are computed so that the between-class variance is maximized.
