Table 6 Quality of hiding and secret recovery at various BPP values using a \(512\times 512\) secret image. Entries show mean±std [margin] for \(\hbox {PSNR}_{c\rightarrow s}\), \(\hbox {SSIM}_{c\rightarrow s}\), \(\hbox {MSE}_{c\rightarrow s}\), \(\hbox {IF}_{c\rightarrow s}\), as well as \(\hbox {PSNR}_{{sec}}\), \(\hbox {SSIM}_{{sec}}\), and \(\hbox {BPP}_{{used}}\) over \(N=30\) images.
