Fig. 4From: Combining PRNU and noiseprint for robust and efficient device source identificationThe PRNU and the noiseprint are estimated from available images of a given camera and the image under test, separately. Thus, the PRNU-based (DPRNU) and the noiseprint-based (DNP) pseudo-distances between the test sample and the reference are separately computed and eventually combined to obtain the final scoreBack to article page
