Witryna20 lip 2024 · PVO-based RDH schemes have the advantage of very low image distortion. That means this series of data hiding schemes can produce a stego-image, the digital image embedded with secret information, with a high peak-signal-to-noise ratio (PSNR) value. However, their embedding capacity is quite limited. Witryna7 gru 2024 · In particular, reversible data hiding (RDH) can perfectly retrieve original images when the embedded payload is correctly extracted [ 1, 2, 3, 4, 5, 6, 7, 8, 9 ]. It is effective not only for natural images but also for medical, military, evidential images, and so forth. Numerous RDH techniques have been proposed for plain images. sharehappiness.cz
