prnu calculation? #15

Hi there, do you examples for PRNU or light FPN calculation from an image? Could you please point it out in doc? Thanks for your great contributions.

Thanks for your interest!

No, we don't have any means to calculate the PRNU or FPN as built-in part of the detector model. The model assumes that you have such information available. We normally use the D'Agostino and Webb three-dimensional noise model to characterise and understand noise patterns in sensors. This technique only shows you what noise is present but does not ascribe the noise to any particular source or origin.
