Is img_as_float more precise than .convert('F')

Seems to have possibly interesting PRNU pattern:

606821d45e Add show_mean_noise.py
Does not 256 precision per channel is too weak to determine the PRNU even with multiple images?

Is imagePrnuEstimateNpArray = imageNpArray - denoise_tv_chambolle correct?

Our current imagePrnuEstimateNpArray = imageNpArray - denoise_tv_chambolle, see:

Given device split into two groups and compare both estimated PRNUs and how they evolved when consider more and more images to estimate them within each group

Should print a 2D figure with the evolving PRNU (with all images for instance) with for each x value a representation of the distribution of PRNU pixel values to see if the PRNU does not converge…

Estimate PRNU of devices on actual dataset and evaluate our method

Maybe pay attention to camera settings potentially affecting the PRNU computation.

Estimate PRNU of devices on actual dataset and evaluate our method

How many images per device is there?

Estimate PRNU of devices on actual dataset and evaluate our method

A 2D table having a colormap and actual accuracy values written in each cell to show the accurracy of our method for all values for both number of images to learn the PRNU and to evalute it.
