RAW image processing

Concerning merging multiple color channels PRNU estimations, I choose to input multiple images instead of multiple Numpy arrays, as I may adjust with GIMP to have brightness and contrast settings…

Backup at least /var/lib/gitea/ on update

Use rsnapshot to reduce the size of backups.

RAW image processing

Should implement estimating the PRNU for the 3 color channels. Considering a raw image as if not interpolating does not seem correct despite each color channel image having the same size as…

Contrairement aux canaux rouge et bleu, l’utilisation du canal vert pour l’estimation du PRNU semble incertaine à cause de la répartition du vert. Est-ce qu’un décalage dans une des…

Are raw values bounded?

Could consider the channel having the most variance on the considered set of images.
