Summary: Traditional PVO can only embed two data bits in a smooth image block, which is insufficient for current demands. To improve capacity, we propose a reference pixel-based reversible data hiding scheme using multi-level PVO with PEE, allowing more than two data bits to be embedded in each iteration while maintaining visual quality and security.

Summary: This paper proposes one-dimensional and two-dimensional flexible patch moving modes to increase the embedding capacity, and an average-difference-based complexity computation method to improve the embedding performance. Multiple pairwise embedding schemes are adaptively applied on blocks with different complexities. Experimental results demonstrate that the proposed flexible patch moving modes work well on many PVO-based methods, and the proposed method achieves a significant improvement in fidelity compared to some state-of-the-art RDH schemes.

Summary: In reversible data hiding, pixel-value-ordering (PVO) is a widely used framework due to its high-fidelity under low-capacity requirements. This study proposes a multi-complexity mechanism called Mutual Complexity to make full use of the complementarity between two context-pixel-selection strategies and mitigate the insufficient feature representation problem. Experimental results demonstrate the effectiveness of Mutual Complexity in controlling embedding distortions in different PVO-based methods.

Summary: The twin image-based methods in the context of Reversible Data Hiding scheme involve organizing pixels in ascending order, modifying the largest and smallest pixel for embedding hidden information, and utilizing techniques such as DPVO and center folding. By introducing a new parameter alpha, the proposed scheme enhances Embedding Capacity (EC) without compromising visual quality. This approach is suitable for embedding a large amount of hidden data, and it has significant implications in image identification, manipulation, and forgery detection areas.

Summary: This paper proposes an efficient color image RDH scheme based on pixel value ordering, which fully utilizes the channel correlation to improve the embedding performance. By pre-sorting the intra-block pixels, larger pixel values are collected preferentially in the prediction stage, effectively improving the embedding capacity. The block complexity value is accurately described by exploiting the texture similarity between the channels in the block selection stage, and the capacity allocation process achieves low complexity and high accuracy.
