Witryna9 lut 2016 · Background/Objectives: Pixel Value Ordering (PVO) based embedding is a method for image based Reversible Data Hiding (RDH) to plant secret data in minimum and maximum pixel values of each block of the image. This paper serves as an extension of a recently proposed PVO scheme with higher security and embedding capacity. 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.
