Improved block redundancy mining based reversible data hiding using multi-sub-blocking
作者：
Highlights：
•
• Exceptional block which produce to-be-shifted errors is regularly further divided for closer correlation of pixels within block.
• Multi-sub-blocking enables the combination of various-sized blocks and thus lead to better capacity-distortion trade-off.
• Pixel value grouping, which is essentially an EL involved further division, can be incorporated with multi-sub-blocking to achieve improved performance.
