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)

Multiwavelet wavelet theory has become a hot one, it is more than wavelet function and a number of scaling function to indicate signal. [1] using fractal interpolation function is the first of a multi-wavelet, as GHM Multiwavelets.
