Receiver operating characteristic for the NP detector and the NCC, for L = 100 and L = 50. (Left) Results for the wavelet denoiser, using JPEG compressed images with a Quality Factor of 92, for the camera Nikon D7000. The results indicate that both the NP and the NCC detectors provide a similar detection performance. (Right) Results for BM3D denoiser, for TIFF images obtained from the Nikon D7000. As we can see, the performance of the detectors decreases with respect to the wavelet denoiser, but the test is still able to obtain an acceptable degree of discrimination, showing that the leakage is still present in the images
