Prediction-error-ordering for High-fidelity Reversible Data Hiding
ICASSP 2019accepted
Pixel-value-ordering (PVO) appears as an efficient solution for high-fidelity reversible data hiding. State-of-the-art PVO schemes split the host image into blocks, sort pixels within the blocks based on their graylevel and, finally, embed data into some differences between the sorted values. This p…
