Use mean as denoiser

Does not seem as precise as bilateral denoiser.

Mean denoiser:

Use mean as denoiser

Current issue is that in theory extracting noise by substracting the average image removes the PRNU, but as shown above we still observe patterns looking like unique artifacts. To avoid removing…
