An improved reversible watermarking scheme using weighted prediction and watermarking simulation

作者：

Highlights：

• Propose a reversible watermarking scheme using weighted prediction and watermarking simulation.

• Impose different weights on two predictions from the watermarked and original regions.

• Conduct watermarking simulation on the original region to further improve prediction accuracy.

• Simulation shows that the proposed scheme outperforms the state-of-the-art using the LP.
