DCT-based_Image_Digital_Watermarking
- 基于DCT域的图像数字水印技术： 摘要：数字水印技术作为数字媒体版权保护的有效办法，近年来在国内外引起了人们极大的兴趣。作者采用了DCT离散余弦变换的算法，对图像这种多媒体数字作品进行了数字水印的嵌入和检测研究。并且使用了高效实用的编程工具MATLAB来介绍了一种DCT域的图像数字水印嵌入和提取的实例，并且在最后对嵌入水印的图像进行了攻击实验，验证了该算法的鲁棒性和不可见性。-Based on the DCT domain imag

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

DCT变换图片压缩
- 里面要求实现基于DCT变换的图片压缩程序，基本上复制以后就可以直接运行。值得一提的是，我里面直接调用了三个个外部的包，如果用eclipse编译器或者其他的话，需要在偏好设置中自行设置，否则会报错。具体设置可以自行百度，很简单的(It requires the implementation of image compression program based on DCT transform. After copying, it can
