/** \class ProjectedLandweberDeconvolutionImageFilter
* \brief Deconvolve an image using the projected Landweber
* deconvolution algorithm.
*
* This filter performs the same calculation per iteration as the
* LandweberDeconvolutionImageFilter. However, at each iteration,
* negative pixels in the intermediate result are projected (set) to
* zero. This is useful if the solution is assumed to always be
* non-negative, which is the case when dealing with images formed by
* counting photons, for example.
