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：  本文章阐述了如何产生m序列，对初学者是一份很重要的资料(This article describes how to generate m sequence, for beginners is a very important information)

这是居于matlab下，7.4用汉明窗、布莱克曼窗设计滤波器，7.5是用Kaiser窗设计滤波器(The example 7.4 is use Hamming hamning blackman design of the lower filter,and the 7.5 is use Kaiser)

说明：  高进制调制中，Gray码映射之后，收端进行的软解映射程序。解映射之后的软信息，可直接用于译码(High-band modulation, Gray code mapping, the collection side of the soft solution mapping procedure. Mapping solution after the soft information, can be directly used for decoding)

这是个matlab M文件，利用其可拟合不同波长下的折射率(This is a matlab M documents, which can be fitted using a refractive index different wavelengths)
