Comment (by MasterQuestionable):

 ͏    Though lack sufficient evidence support:
 ͏    The described approach appears to be the theoretical optimal method
 for denoise..? (base method for all kinds)
 ͏    Anything further would only involve selecting more suitable strength
 for each exact sample.

 ͏    Which introduces no method noise (like JPEG, H.264 etc. did).
 ͏    And considering what makes denoise: the algorithm just seems to
 achieve what theoretically best achievable? (actually more appropriate
 than typical "weighted" NLM...)
 ͏    Plus the idempotence...

 ͏    Probably a revolution to all lossy compression schemes?
