Detailed Description

template<class THistogram>
class itk::HistogramToProbabilityImageFilter< THistogram >

The class takes a histogram as an input and gives the probability image as the output. A pixel, at position I, in the output image is given by.

\[ f(I) = \frac{q_I}{\sum_{i \in I} q_I} \]

where $q_I$ is the frequency of measurement vector, I.

This 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 float.

This is useful in plotting the joint histograms during registration.
