代码说明:

  当要隐藏信息时,在MATLAB的命令窗内输入命令: hide = myhide(carry,signal,x,y); carry 用你的原始载体文件名代替,signal 用你所要隐藏的文件名代替 carry 和 signal 都必须是 *.* 的形式(注意不能省略单引号) x,y 是选取隐藏信息的位置坐标,在(x,y)和(y,x)处 生成的伪装载体文件名为hide.bmp 注意myhide.m文件,载体文件,隐藏文件都要在当前目录(current Directory)下 当要提取信息时,在MATLAB命令窗内输入命令: behidden = myinhide(carry,x,y); carry 用你的伪装载体文件名代替,格式为 *.* (注意不要丢掉单引号) x,y 是选取隐藏信息的位置坐标,在(x,y)和(y,x)处,这必须和嵌入时所选位置一致。 提取出的信息文件名为behidden.bmp 同样,要注意behidden.m和伪装载体文件都要在当前目录(current Directory)下(when to hide information, in order MATLAB within a window orders : hide = myhide (carry, signal, x, y); Carry with you the original document name instead vector, signal used to hide your name in the paper and instead carry signal must be in the form of*.* ( not to single quotes omitted) x, y is to select the location of hidden information coordinates (x, y) and (y, x) The formation of camouflage vector document, entitled hide.bmp attention myhide.m documents, vector documents hidden all the documents in the current directory (current Directory) to retrieve information when, in order window MATLAB import order : behidden = myinhide (carry, x, y); carry using your camouflage vector file name instead, the format for*.* (take care not to lose a single quote) x, y election Hiding information )
