[Retracted] Neural Reversible Steganography with Long Short-Term Memory

Figure 12

Stego images generated by embedding a random bitstream with different threshold values that regulate the steganographic channel. Numerical data express the PSNRs and maximum embedding rates. (a) θ = 0, 51.52 dB, 0.1652 bpp. (b) θ = 0, 51.51 dB, 0.1607 bpp. (c) θ = 0, 51.29 dB, 0.0470 bpp. (d) θ = 0, 51.50 dB, 0.1554 bpp. (e) θ = 1, 46.72 dB, 0.3240 bpp. (f) θ = 1, 46.71 dB, 0.3248 bpp. (g) θ = 1, 45.62 dB, 0.1057 bpp. (h) θ = 1, 46.68 dB, 0.3191 bpp. (i) θ = 2, 44.46 dB, 0.4039 bpp. (j) θ = 2, 44.53 dB, 0.4150 bpp. (k) θ = 2, 42.48 dB, 0.1581 bpp. (l) θ = 2, 44.53 dB, 0.4210 bpp.
