Detailed Description

template<class TInputImage1, class TInputImage2, class TOutputImage>
class otb::KullbackLeiblerDistanceImageFilter< TInputImage1, TInputImage2, TOutputImage >

Implements neighborhood-wise the computation of KullbackLeibler distance over Edgeworth approximation.

This filter is parametrized over the types of the two input images and the type of the output image.

Numeric conversions (castings) are done by the C++ defaults.

The filter will walk over all the pixels in the two input images, and for each one of them it will do the following:

cast the input 1 pixel value to double
cast the input 2 pixel value to double
compute the first four cumulants of the two pixel values
compute the value of the Edgeorth approximation of the KL distance
cast the double value resulting to the pixel type of the output image
store the casted value into the output image.

The filter expect all images to have the same dimension (e.g. all 2D, or all 3D, or all ND)
