中文说明：资源描述这是我的一个代码，主要是在信息隐藏方向进行应用，他是可以利用图像的分块，将M*N的图像可以分成m*n的不覆盖的字块，可在字块内进行操作，比如说进行快内像素均值的计算，或其他定义的一些特征值计算，最终通过这些计算进行信息的锲入，并可通过这些锲入的策略进行数据的提取。

Application backgroundThis is one of my code, mainly in information hiding in the direction of application, he is making use of the image block, m * n image can be divided into mxn is not covered by the word blocks can be operated within a block of words, for example within the pixel average calculation, or other definitions of some characteristics values are calculated by these calculations for information wedged into the, extraction and data through the wedge into the strategy.
