A JPEG Reversible Data Hiding Algorithm Based on Block Smoothness Estimation and Optimal Zero Coefficient Selection

To address the issues of image quality degradation and file size expansion encountered during reversible data hiding (RDH) of JPEG images, a JPEG reversible data hiding algorithm based on block smoothness estimation and optimal zero coefficient selection is proposed. Firstly, a block smoothness esti...
