PVO-based reversible data hiding using adaptive multiple histogram generation and modification

作者：

Highlights：

• An adaptive PVO-based reversible data hiding scheme is proposed.

• The difference of pixel local complexity is efficiently exploited.

• Proper modification manners are applied to different prediction-error histograms.

• Pairwise modification on multiple 2D histograms is proposed for improvements.

• The proposed scheme outperforms some advanced works with good image quality.
