The code implements the following paper: Guorong Xuan, Jiang Zhu, Jidong Chen, Shi Y.Q., Zhicheng Ni, Wei Su, "Distortionless data hiding based on integer wavelet transform" IET Electronics Letters, Volume: 38, Issue 25, page 1646- 1648, December 2002. (ISSN: 0013-5194) The watermark embedding and extraction modules have been implemented separately. The watermark embedding module embeds the watermark using bitplane compression in the integer wavelet transform domain. The watermark extraction module extracts the previously embedded watermark and restores the original image. A logo image is used as a watermark but can be replaced with any thing.

关于系未分配问题的解和matalb程序，随机生成100组数据(Distribution on the system is not the solution and matalb procedures, randomly generated 100 sets of data)

里边包含了一个如何区分6和9的代码以及用最小距离法、梯度法以及K-NN方法对样本进行的分类代码(Inside contains an example of how to distinguish between 6 and 9, as well as the code with the minimum distance method, the gradient method and K-NN method for sample classification codes)

这个程序是通信系统的CRC校验，完成了这方面的功能(This program is communication systems CRC, to complete the function of this area)

说明：  复杂网络研究与建模 总起来说这是一个关于矩阵的运算，用到了c语言里面的东西，实现一个矩阵的逆运算和矩阵的转置等，最终实现的是一个初始节点为4个节点的有向图，随即扩展为一个10000*10000的巨型矩阵，得到该有向图的图形， 与计算机图形学类似，该程序是在构建了一个算法后，用MATLAB实现了一个无标度网络的图形中的各个节点的概率密度，并根据各个节点的概率密度绘出该图 (将中文译成英语 And modeling complex networks Collectively this is a computation on the matrix, use the stuff inside c language to realize the inverse of a matrix and a matrix, etc., and ultimately is an initial node to four nodes directed graph, then Expands to a huge matrix 10000* 10000, by the digraphs graphics, And similar computer graphics, the program is built upon an algorithm, using MATLAB to achieve a scale-free network each node in the graph the probability density and probability density according to each node in the graph drawn )
