/** \class RichardsonLucyDeconvolutionImageFilter
* \brief Deconvolve an image using the Richardson-Lucy deconvolution
* algorithm.
*
* This filter implements the Richardson-Lucy deconvolution algorithm
* as defined in Bertero M and Boccacci P, "Introduction to Inverse
* Problems in Imaging", 1998. The algorithm assumes that the input
* image has been formed by a linear shift-invariant system with a
* known kernel.
*
* The Richardson-Lucy algorithm assumes that noise in the image
* follows a Poisson distribution and that the distribution for each
* pixel is independent of the other pixels.
*
* This code was adapted from the Insight Journal contribution:
*
* "Deconvolution: infrastructure and reference algorithms"
