#include <itkOtsuThresholdImageCalculator.h>
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.

void itk::OtsuThresholdImageCalculator< TInputImage >::Compute | ( | void | ) |
Compute the Otsu's threshold for the input image.
|
virtual |
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.
Reimplemented from itk::Object.
|
virtual |
Run-time type information (and related methods).
Reimplemented from itk::Object.
|
virtual |
Set/Get the number of histogram bins. Default is 128.
|
virtual |
Return the Otsu's threshold value.
|
static |
Method for creation through the object factory.
|
private |
|
protectedvirtual |
Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
Reimplemented from itk::Object.

Set/Get the number of histogram bins. Default is 128.
void itk::OtsuThresholdImageCalculator< TInputImage >::SetRegion | ( | const RegionType & | region | ) |
Set the region over which the values will be computed
