Table 4 The error rate in the DCT block with different NAO before 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 (\(\times 10^{-2}\)) | 0.17 | 1.19 | 2.18 | 2.65 | 2.68 | 2.98 | 3.19 | 3.64 | 4.09 | 4.20 | 4.72 | 5.00 | 5.71 | 6.35 | 6.68 | 6.68 |
