是Digital signal processing--using Matlab中的一些函数，那本书网上可以找到，对学习数字信号处理可以说是相当有用的。(Is the Digital signal processing- using Matlab some function, that book can be found online on the study of digital signal processing can be said to be quite useful.)

This is for chapter 06

共轭梯度法，是数值分析中很重要的一种，源码为其在matlab中的实现。(Conjugate gradient method, numerical analysis is a very important one in the matlab source code for its realization.)

说明：  史上最详细的matlab教程，涵盖了matlab使用的各个方面，很有帮助作用(The history of the most detailed tutorial matlab, covering all aspects of the use of matlab, helpful role in)

基于 DCT(离散余弦变换 )域的信息隐藏算法是目前应用最广的变换域算法 ,此类算法的最大不足是嵌信息量小。通过分析 DCT域隐藏算法隐藏容量少的原因 ,提出了一种大容量的 DCT域信息隐藏算法。算法首先对载体图像进行频谱均匀化处理 ,然后对图像进行全局 DCT变换 ,并将隐藏信息嵌入到载体图像的低频 DCT系数上 ,信息嵌入采用分段量化的方法实现 ,提取隐藏信息时不需要原始载体图像。实验结果表明 ,该算法的嵌入容量大 ,不可感知性好。(Based on DCT (discrete cosine transform) domain information hiding algorithm is the most widely used transform domain algorithms, the largest of these algorithms is the lack of a small amount of information embedded. Hiding Algorithm for DCT domain by analyzing the hidden reasons for the low capacity, a large capacity of information hiding algorithm for DCT domain. Firstly, the spectrum of the carrier image homogenization, and then the image is a global DCT transformation, and hidden information embedded into the image of the low-frequency DCT coefficients, the information embedded in the methods used to achieve sub-quantization, extract hidden information without the original Vector image. Experimental results show that the algorithm embedding capacity, can not be perceived good.)
