This is the official code implementation of the paper "An Adaptive Method for Camera Attribution under Complex Radial Distortion Corrections"

• Install MATLAB Image Processing Toolbox
• Download the Camera-fingerprint package and run the function compile.m in folder CameraFingerprint/Filter
• 5G of RAM

• Download the Camera Fingerprints we used in our paper from here, unzip "CAMERA_FINGERPRINTS.zip" and move them into PRNU_FILES/

Move all the functions of Camera-fingerprint in functions/ :

• mv CameraFingerprint/Filter/* functions/
• mv CameraFingerprint/Functions/* functions/
• mv CameraFingerprint/*.m functions/
• enter in functions/ and run in MATLAB compile.m

• if you are on Linux you may face problems due to unsupported C compilers in MATLAB. Send a mail to [email protected] if you need a pre-compiled version of these C / C++ files or contact the authors of Camera-fingerprint.

• a set of test images are included in test-images/ and the respective Camera Fingerprint can be found in PRNU_FILES/
• a subset of the images we used to test our code on out-camera correction can be downloaded here. We couldn't include all the images for a matter of privacy.

• run main.m to test our code on some of our test image. main.m computes the PCE and CPCE value both for the H1 and H0 hyphothesis.
• change the paths of Fingerprint and im to test our code on your data.

Changing the parameters transf_idx and flag_direct of the functions functions/ADAPTIVE_*.m it is possible to test specific variants of our code.

• ID, Lin: use ADAPTIVE_Inv_and_Dir.m + transf_idx=6 and flag_direct=0
• DI, Lin: use ADAPTIVE_Inv_and_Dir.m +transf_idx=7 and flag_direct=1
• ID, Cub: use ADAPTIVE_Inv_and_Dir.m +transf_idx=5 and flag_direct=0
• DI, Cub: use ADAPTIVE_Inv_and_Dir.m +transf_idx=4 and flag_direct=1
• Inv, Cub: use ADAPTIVE_Inv_or_Dir.m +transf_idx=5 and flag_direct=0
• Dir, Cub: use ADAPTIVE_Inv_or_Dir.m +transf_idx=4 and flag_direct=1
• Inv, Lin: use ADAPTIVE_Inv_or_Dir.m +transf_idx=6 and flag_direct=0
• Dir, Lin: use ADAPTIVE_Inv_or_Dir.m +transf_idx=7 and flag_direct=1
