Should generare a white image with vignetting and see how the FFT looks like.
Let us consider the FFT considering a centered crop of the estimated PRNU.
I was about to say that I am surprised that the background of the FFT looks having similar values to everything else but we are in logarithmic scale so the colors differ linearly while the actual…
matplotlib: Adapt the color scale to leverage it the most when zoom
In fact if I use the center he specified (that is (509, 546)) that is not the center of the image (that is (552.5, 528)), then I get:
On the crop we seem to particularly see the lines artifacts, see #70.
For Rafael 23/04/24 estimated PRNU with mean denoiser:
