Detailed Description

template<class TInputImage, class TOutputImage, class TMaskImage = TOutputImage>
class itk::OtsuThresholdImageFilter< TInputImage, TOutputImage, TMaskImage >

Threshold an image using the Otsu Threshold.

This filter creates a binary thresholded image that separates an image into foreground and background components. The filter computes the threshold using the OtsuThresholdCalculator and applies that theshold to the input image using the BinaryThresholdImageFilter.
