说明：  小波域数字水印嵌入程序。 实现对数字图像进行水印嵌入和检测。(Digital watermark embedding in wavelet domain. Implementation of digital image watermark embedding and detection.)

伪随机码或称PN码，是扩频通信中不可缺少的一种序列。扩频通信，简单的说来就是通过一组相关性很强的伪随机序列，使原有的信号按照伪随机序列的特性出现。(Said pseudo-random code or PN code, spread spectrum communication is an indispensable sequence. Spectrum, simple to say is highly relevant by a group of pseudo-random sequence, so that the original signal in accordance with the characteristics of pseudo-random sequence appears.)
