实现了最低有效位LSB水印算法。
压缩文件中含有原图,可直接放到Matlab中运行。-We realize the least significant bit (LSB) watermarking algorithm. It contains all the images you need,and it can be run directly in Matlab.

图像的组成无非是一些字符串或者一些字节组成的字符串,然而,每一个字节数据位的重要度并不是一样的,两个相邻字节往往只有低位是不一样的。例如:00100110和00100111代表了两个不同渐变度的红色,但是就人眼是分辨不出来的。最低有效位LSB算法,就是利用这一点,达到图像压缩,或者数字水印的功能。-The composition of the image is nothing more than some number of bytes or string composed of string,

基于空域的脆弱水印算法,该方法最具代表性的是最低有效位(LSB)法,也就是文件中的方法,两个文件分别给出了水印的生成和检测。-Airspace based on fragile watermarking algorithm, the method is the most representative of the least significant bit (LSB) method, which is the method of the document, two documents were
