Keep a copy of this repository on another device
Also pay attention to keep a recent copy of this repository all time long, as I do not have a local copy of meta-git stuff (issues etc).

Maybe just consider like 3 different images, as I have done in the following issue for technical reasons:

Estimating PRNU on Gaussian noise images
Could render intermediary image differences, as it is easy to see an almost black uniform image but it is hard to compare 2 random images. However, this assumes that the color scale for each image…

Estimating PRNU on Gaussian noise images
Showcase an example and now make a curve to make it clearer. Note that if want a maximum precision curve, may have to pay attention to complexity.
