(Left) Information Leakage Bound (in bpp) vs L for three different cameras in the set, showing the expected decrease of the leakage with respect to L. (Right) Receiver operating characteristic for the NP detector and the NCC, for L = 100 and L = 50. Results for the wavelet denoiser. Solid lines: Nikon D7000; dashed lines: Canon 600D. The results indicate that both the NP and the NCC detectors provide a similar detection performance for the Nikon D7000. In contrast, the results for the Canon 600D are less favourable, which is in agreement with the results for the lower bound depicted in Table 1. In both cases, the detection performance degrades significantly when L increases
