Detailed Description

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.

This code was adapted from the Insight Journal contribution:

"Deconvolution: infrastructure and reference algorithms" by Gaetan Lehmann https://doi.org/10.54294/tvgfv1
