Reversible data hiding using invariant pixel-value-ordering and prediction-error expansion

作者：

Highlights：

• A high fidelity reversible image data hiding scheme is proposed.

• The reversibility is guaranteed by keeping pixel-value-ordering of each image block invariant after embedding.

• The maximum-valued (or minimum-valued) pixels in a block are taken as a unit to embed data.

• A mechanism of advisable payload partition and pixel-block-selection is adopted to optimize the embedding performance.
