The cameras themselves might not, but in order to get a decent picture you will need to apply demosaicing and gamma correction in software at the very least, even with high end cameras.
Right, and the point ppl are making upthread is that deterministic signal processing and probabilistic reconstruction approaches are apples and oranges.
Deterministic within a single image yes, but not within arbitrary subsections. Classical filters aren’t trying to reconstruct something resembling “other images it’s seen before”. Makes a difference both in theory and practice.
