Detailed Description

template<typename TInputImage, typename TOutputImage, typename TMaskImage = TOutputImage>
class itk::TriangleThresholdImageFilter< TInputImage, TOutputImage, TMaskImage >

Threshold an image using the Triangle Threshold.

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