Improved pvo-based reversible data hiding

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.
