利用LSB算法去实现了电子水印技术。代码完全实现了嵌入以及提取， 算法同时包含了4种攻击算法以及利用psnr测量提取的水印和攻击后提取的水印(This algorithm describes digital watermark technique by using LSB. This code implement embedding and extraction. At the meanwhile, this algorithm includes 4 different kinds of attacks and in the end, measure psnr between extracted watermark and attacked extracted watermark)

Simple code to write a file in C

这个方法有两个好处。 （ a ）虽然只是一个半径差逼近，很容易找到最高在一个小蓄电池，因为通过降低 隐平滑做的蓄电池。（ b ）在同一时间处理时间搜索减少 (Pattern Recognition and Image Procesing Group. The size of the accumulator is varied as hierarchical voting is performed. This has two advantages. [a] While the radius is only a poor approximation, it is easier to find the maximum in a small accumulator and because by means of the downsampling implicit smoothing is done to the accumulator. [b] At the same time processing time for the search is reduced.)

信息论基础，描述了香农定理，熵的概念以及计算方法(Elements.of.Information.Theory.Jul.2006)

说明：  关于求混沌嵌入维的程序，matlab上运行(Embedding dimension of chaotic process)

在matlab中用到的函数，用来方便构造小波和尺度函数(The function of the matlab in use, easy to construct wavelet and scale functions)

A律压缩器子程序，用于matlab中A律压缩器子程序调用(A-law compression subroutine for A-law compressor routine matlab call)

本程序可以作为matlab插值使用，并可经过改变变量进行修改(This program can be used as matlab interpolation used and may be modified after changing the variable)
