- 频域法加入数字水印的原理是首先将原始信号(语音一维信号、图像二维信号)变换到频域,常用的变换一般有DWT、DCT、DFT、WP和分形。然后,对加入了水印信息的信号进行频域反变换(IDWT、IDCT、DFT、WP),得到含有水印信息的信号。-Frequency-domain digital watermarking method by adding the principle is that first of all, the original signal (voice signal of on
MatermarkingDWT_DCT
- 提出一种基于DWT和DCT域的有意义二值图像数字水印算法 利用Arnold变换对水印序列进行置乱,消除 象素的空间相关性,增加水印的安全性 而结合小波变换和离散余弦变换的特性,将水印信息嵌入到图像变换域的低频和 中频系数中,提高水印的鲁棒性和不可见性 实验证明该算法具有较好的抗压缩、抗噪音和抗剪切性。-Watermarking in DWT and DCT area
