signature
- 该目录包含了基于可移植的C语言的数字水印算法的代码。这些代码具有示范 性的意义，且有一定的鲁棒性。 需要安装NetPGM的程序包（用来存取pgm格式图像），然后才能在linux下面编译。 NetPGM是图像文件的输入/输出软件包。可以在网上搜索得到。我们已经对 256灰度级，512×512大小的图像进行了测试。程序编译后的调用格式如下（以encode为例）： wm_cox_e -s cox.sig -o wm_image.pgm image.pgm 其中，-s表示要
matlab_watermark
- 本文算法是将24 位真彩图的亮度分量分块 DCT ,然后利用DCT 量化系数的奇偶特性嵌入8 位灰度水印图,并通过PN 序列加密来保证水印的 安全性。算法中,将灰度图像转换为二进制数据 流,置乱后扩频调制,隐藏在宿主DCT 系数量化值 中,提取时不需要宿主信号,实现水印信号的盲提 取。-This algorithm is 24-bit true color pictures of the luminance component of block DCT, quantiza
