说明: 为了达到较好的隐藏效果,本文采用游程编码的方法在二值图像中隐藏信息。秘密信息嵌入时修改二值图像的游程长度,如果秘密信息为是0,则修改该游程长度为偶数;如果秘密信息的取值与游程长度的奇偶性相匹配,则不改变游程长度。提取时根据游程长度奇偶性提取出秘密信息。在信息隐藏时,改变游程的奇偶性时通过对下一个游程的第一个像素值进行修改,因此当下一个游程长度为1时通过改变当前有成的值实现。(In order to achieve better hiding effect, we use run length encoding method to hide information in two value images. When the secret information is embedded, the length of the travel length of the two value image is modified. If the secret information is 0, the length of the travel length is even even. If the value of the secret information is matched with the parity of the length of the run, the length of the journey is not changed. The secret information is extracted according to the parity of run length. In information hiding, changing the parity of the journey is modified by the first pixel value of the next run, so the current length is 1 by changing the current value.)
