hi! sure, everything that improves noise reduction will be a welcomed addition. glancing over the paper you mention, it is based on non-local means and a global minimisation/total variation step. keep in mind that for interactive usage we need to render several megapixels through all necessary mod

[darktable-dev] Regularized NL Means Denoise for poisson noise

2018-02-17 Thread Björn Sozumschein
Hello all, the Paper "Adaptive regularization of the NL-means: Application to image and video denoising" by Sutour et al, 2014 provides a nice overview regarding methods to adapt the NL Means algorithm for poisson noise and introduces regularization in order to remove typical artifacts. As far as
