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.)

说明: Donoho提出的小波阀值去噪的基本思想是将信号通过小波变换(采用Mallat算法)后,信号产生的小波系数含有信号的重要信息,将信号经小波分解后小波系数较大,噪声的小波系数较小,并且噪声的小波系数要小于信号的小波系数,通过选取一个合适的阀值,大于阀值的小波系数被认为是有信号产生的,应予以保留,小于阀值的则认为是噪声产生的,置为零从而达到去噪的目的。尺度不变特征变换(Scale-invariant feature transform,SIFT),是用于图像处理领域的一种描述。这种描述具有尺度不变性,可在图像中检测出关键点。(The basic idea of wavelet threshold de-noising proposed by Donoho is that the wavelet coefficients generated by the signal after passing through the wavelet transform (Mallat algorithm) contain the important information of the signal. After the wavelet decomposition, the wavelet coefficients of the signal are larger, the wavelet coefficients of the noise are smaller, and the wavelet coefficients of the noise are smaller than the wavelet coefficients of the signal. By selecting a suitable threshold, the wavelet coefficients of the noise are larger than the valve The wavelet coefficients of values are considered to be generated by signals, which should be preserved. The ones less than the threshold are considered to be generated by noise, which is set to zero to achieve the purpose of denoising.)
