R5 Low ISO Noise Reduction (cont.)
10

A continuation of this interesting thread. It took me a while but I have now the auto-correlation of the two G channels combined. The bright blue squares have values about 23% of the center one, all eight of them.

This is based on a 2048x2048 centered square. Dealing with the missing (on purpose) R and B values due to the Bayer structure was a RPITA.

R5, ISO 100, G+G2 auto-correlation

It is amazing how much order is there in the noise, isn't it?
