Reversible watermarking scheme for medical image based on differential evolution.

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. [ABSTRACT FROM AUTHOR]
