watermarked
- 用MATLAB实现数字音频水印的嵌入和提取，即是在一段音频水印中嵌入二维图像。-Using MATLAB realization of digital audio watermark embedding and extraction, that is, over a period of two-dimensional audio watermark embedded image.
Wavelet-Watermark_
- 这个Matlab程序的最主要功能在water.m文件中，当你调用这个函数之后，系统会提示你给哪个图像文件加水印。blockdwt2.m文件，用于在小波频域添加水印logo图片。dmg.m文件产生水印logo图片。watdet3.m文件中的函数实现的功能是检查是否有水印的logo存在。-The main function of Matlab procedures in water.m document, when you call this function, the system will pr
LSB-Data-Hiding-Image
- 图像的组成无非是一些字符串或者一些字节组成的字符串，然而，每一个字节数据位的重要度并不是一样的，两个相邻字节往往只有低位是不一样的。例如：00100110和00100111代表了两个不同渐变度的红色，但是就人眼是分辨不出来的。最低有效位LSB算法，就是利用这一点，达到图像压缩，或者数字水印的功能。-The composition of the image is nothing more than some number of bytes or string composed of string,
