摘要
本文提出了两种不同的变换域方法:一种是基于DCT域的自适应水印算法;另一种是基于多分辨率分解(DWT)的水印算法。实验结果表明,这两种水印算法具有良好的性能,实现的水印具有不可见性,而且对于常见的图象处理具有很好的鲁棒性。
In this paper, an adaptive digital watermarking technique in the DCT domain and a digital watermarking technique based on multiresolution decomposition (the DWT domain) are proposed. Experimental results demonstrate that the two watennarking algorithms have better effect: The watermark is invisible and robust against common image processes.
