matlab编写的对二值图像的数字水印添加与提取程序。压缩包中有示例图片。可以添加水印，结果肉眼不易分辨出变化，不影响使用。可加入信息长度达100个字节。提取时可验证是否被修改过，如修改不严重，可提取隐藏信息，如果修改过多，则只能确定是否有修改，而不知道隐藏的信息是什么(matlab prepared binary image of the digital watermark added and extraction procedures. Compression package has sample images. Can add watermarks, the results of the changes are not easily distinguishable from the naked eye, does not affect use. Can be added to the information length of 100 bytes. Verifiable extraction has been modified, such as modification is not serious, can extract hidden information, if too many modifications, you can only determine whether changes were needed, they do not know what information is hidden)

说明：  关于MUSIC算法的源代码。很好用的(MUSIC algorithm on the source code. Good used)

说明：  本程序采用matlab求解常见的几种偏微分方程(This procedure uses matlab partial differential equations to solve several common)

这里主要对LMS算法及一些改进的LMS算法（NLMS算法、变步长LMS算法、变换域LMS算法）之间的不同点进行了比较，在传统的LMS算法的基础上发展了LMS算法的应用。(here on the main LMS algorithm and some improvements to the LMS algorithm (NLMS. modified LMS algorithm, transform domain LMS algorithm) between the different points of comparison, in the traditional LMS algorithm developed on the basis of the LMS algorithm application.)

极坐标下的分贝画图。matlab中极坐标画图函数为polar，但是无法画出转化为dB的图形，此函数为画db为单位数据的极坐标图形。(Db drawing in polar coordinates . matlab polar coordinate drawing functions for the polar , but can not draw dB graphics , this function graphics for painting db data in polar coordinates .)
