template<typename THistogram, typename TImage = Image<double, 3>>
class itk::HistogramToEntropyImageFilter< THistogram, TImage >
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.
\[ f(I) = -p \log_2 p \]
where
\[ p = \frac{q_I}{\sum_{i \in I} q_I} \]
where \(q_I\) is the frequency of measurement vector, I.
\(p\) is the frequency of a measurement vector by the sum of all frequencies = Probability of the measurement vector
The output image is of type double.
This is useful in plotting the joint histograms during registration.
