Detailed Description

template<class TInputImage>
class itk::NewOtsuThresholdImageCalculator< TInputImage >

Computes the Otsu's threshold for an image.

This calculator computes the Otsu's threshold which separates an image into foreground and background components. The method relies on a histogram of image intensities. The basic idea is to maximize the between-class variance.

This class is templated over the input image type.

Warning
This method assumes that the input image consists of scalar pixel types.
