Detailed Description

template<class THistogram, class 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 the measurement vector

The output image is of type double.

This is useful in plotting the joint histograms during registration.
