Reversible watermarking scheme for medical image based on differential evolution
作者：
Highlights：
• A reversible watermarking method is proposed with wavelet transforms and SVD.
• Signature and logo data are inserted by recursive dither modulation algorithm.
• DE is explored to design the quantization steps optimally.
• Good balance of imperceptibility, robustness and capacity is obtained by DE.
• Experiments show good performance and outperform the related algorithms.
