High Capacity Reversible Watermarking for Audio by Histogram Shifting and Predicted Error Expansion
Being reversible, the watermarking information embedded in audio signals can be extracted while the original audio data can achieve lossless recovery. Currently, the few reversible audio watermarking algorithms are confronted with following problems: relatively low SNR (signal-to-noise) of embedded...
