#include <itkHistogramToEntropyImageFilter.h>
The class takes a histogram as an input and gives the entropy image as the output. A pixel, at position I, in the output image is given by.
where
where is the frequency of measurement vector, I.
is the frequency of a measurement vector by the sum of all frequencies = Probability of the the measurement vector
The output image is of type double.
This is useful in plotting the joint histograms during registration.

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.
