- 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

Audio-Watermarking-in-DCT
- 本文在DCT噪声信号模型研究的基础上,提出了一种新的音频水印嵌入位置选择策略和一个应用该策略的自适应音频水印算法. 通过定义DCT系数的噪声敏感度,建立了水印嵌入位置和嵌入水印后的音频信号的听觉感知性之间的关系,根据音频水印的不可听性的要求选择最优的嵌入位置,然后调节水印强度来满足鲁棒性的要求,从而最大程度地保持音频水 印的不可听性和鲁棒性,为解决音频水印嵌入过程中不可听性和鲁棒性之间的矛盾提供了一种策略.-Though m any w orks in the literature agre
MP3-watermarking
- ：针对MP3 编码方式和帧结构进行分析，利用帧中的比例因子提出了一种压缩域水印算法。算法通过引入帧变化分析步 骤，很好地实现了水印的自适应嵌入。对于不同的系统要求，还可以通过修改门限信噪比的值SNRlim按需进行水印嵌入，使算法 具有更大灵活性。同时在牺牲一定的嵌入空间前提下，实现了水印信息的自同步。实验表明，对于不同风格的音乐，该水印算法 具有很好的不可听性。-In this paper，the encoding method and the frame structure of
