Detection statistics for the Neyman-Pearson detector (14) (a) and the Normalized Correlation coefficient detector (19) (b) on a set of 190 JPEG-compressed images (Nikon D7000 camera), where the PRNU is estimated from the first 50 images. The performance of both detectors decreased slightly, as the compression process enhances the denoising. In both cases, the two levels can still be differentiated
