真值矩阵

This paper presents a non-watermarking algorithm based on the most significant bits to construct the key. Firstly, the binary watermarking image is scrambled and extended to the size of the main image. Then the value of every pixel of the watermarking image is compared with that of the corresponding MSB of the main image. When the compared value is true, the location of the main image is marked by a zero matrix, and the marked zero matrix is a key that can be used to detect the watermarking image later.

本文提出一种基于最高有效位构造密钥的零水印算法，先将二值水印图像置乱并拓展为载体图像的大小，再将其像素值与载体像素的MSB进行对应比较，当比较结果为真时，用一个零矩阵来标记载体像素的位置，被标记过的零矩阵作为密钥来检测水印。

I am sure after a few weeks of adaptation and familiarization I will have no difficulty in functioning on a daily basis in an English speaking society or in participating fully in graduate studies.
