Abstract
Sensor mode noise (SPN) is a kind of noise-like spread spectrum signal, which is often
used for image source identification and camera source identification. It is an important
indicator of image quality evaluation, and it is often considered as a reliable device fingerprint.
In most cases, SPN can be roughly regarded as the noise obtained by the difference operation
between the image and its denoised version. However, the sensor mode noise extracted by
traditional methods will be
