Table 5 The error rate in the DCT block with different NAO after three times of robustness embedding
From: Robust JPEG steganography based on the robustness classifier
NAO | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
Error rate (\(\times 10^{-2}\)) | 0.15 | 0.62 | 1.26 | 1.45 | 1.51 | 1.63 | 1.76 | 2.23 | 1.53 | 1.62 | 1.41 | 1.76 | 2.00 | 3.01 | 2.23 | 3.95 |
