摘要
提出了在同一载体信号的时域和小波域分别嵌入水印的算法,利用小波变换的多分辨率特性和SCS算法的盲检测性,水印的嵌入采用量化的方法,水印的提取不需要原始载体信号。实验结果表明,基于SCS编码的数字水印算法鲁棒性高、隐藏容量大,具有广泛的实际应用。
This paper presents a algorithm which can embed time domain watermark and wavelet domain watermark at same carrier signal,using wavelet transform multi-resolution features and SCS algorithms of blind detection,the watermark embedding using quantitative methods,the watermark extraction does not require the original carrier signal.Experimental results show that SCS-based coding algorithm for digital watermarking performs high Robustness and has large capacity,which has a wide range of applicarions.
