Are there any denoising algorithms that remove Moiré patterns? It would be a welcome addition to the stock iPhone and Android cameras.

  If you don’t need it to be perfect it is actually not too difficult. A notch filter could be enough remove most of the pattern provided that you have a good way of guesstimating its frequency

    Being very slightly out of focus would probably be the best solution

    It looks like Adobe Raw added a dedicated moire reduction slider to their denoising features a few years back. I wonder how it operates.
