Table 4 Quality of hiding and secret recovery at various BPP values Using Secret Image Size 64*64. 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.
