在MATLAB里，基于dct域,实现在二维图像中嵌入数字水印 并提取。(In MATLAB, the dct-based domain, the realization of two-dimensional images in the digital watermark embedding and extraction.)

In computing, the kernel is the main component of most computer operating systems it is a bridge between applications and the actual data processing done at the hardware level. The kernel s responsibilities include managing the system s resources (the communication between hardware and software components).[1] Usually as a basic component of an operating system, a kernel can provide the lowest-level abstraction layer for the resources (especially processors and I/O devices) that application software must control to perform its function. It typically makes these facilities available to application processes through inter-process communication mechanisms and system calls.

在输入输出信号中加入高斯白噪声。这是在很多工程领域必须加入的。此文件是matlab中信号加入高斯白噪声的文件(In the input and output signals in white Gaussian noise. This is in many engineering fields must be added. This file is in matlab adding Gaussian white noise signal file)
