Table 6 \(P_{e}\) and distortion between cover images and cover images after robustness embedding in methodIII with different \(\alpha\) when \(h = 3\) and \(\text {phase}_{\text {max}} = 4\)
From: Robust JPEG steganography based on the robustness classifier
\(\alpha\) | 1 | 2 | 3 | 4 | 5 |
|---|---|---|---|---|---|
\(P_{e}\) | 0.0073 | 0.0073 | 0.0068 | 0.0068 | 0.0067 |
\(Distortion(\times 10^5)\) | 1.1227 | 1.2595 | 1.6184 | 1.9863 | 2.4008 |
