The implementation is based on Digital Camera Identification from Sensor Pattern Noise (Lukáš, Fridrich and Goljan). My multimedia forensics bibliography lists more papers on this topic.
Prerequisites:
- pip install pillow cython pywavelets
- Run python setup.py build_ext in
accel, then link the .so output into that directory.
Given a path containing PNG-format images, calculates the characteristic noise signal and outputs it to a file.
Outputs the correlation of a given characteristic noise signal and test image(s).
