Table 8 \(P_{e}\) and distortion between cover images and cover images after robustness embedding of methodIII with different \(\text {phase}_{\text {max}}\) when \(h = 3\) and \(\alpha = 3\)
From: Robust JPEG steganography based on the robustness classifier
\(\text {phase}_{\text {max}}\) | 2 | 3 | 4 | 5 | 6 |
|---|---|---|---|---|---|
\(P_{e}\) | 0.0073 | 0.0068 | 0.0068 | 0.0068 | 0.0068 |
\(Distortion(\times 10^5)\) | 1.4080 | 1.5202 | 1.6184 | 1.6888 | 1.7449 |
