Description: This scheme is initiated by Ziv and Lempel [1]. A slightly modified version is described by Storer and Szymanski [2]. An implementation using a binary tree is proposed by Bell [3]. The algorithm is quite simple: Keep a ring buffer, which initially contains "space" characters only. Read several letters from the file to the buffer. Then search the buffer for the longest string that matches the letters just read, and send its length and position in the buffer. Platform: |

Description: 哈夫曼树
设计2进制前缀编码的方法如下.
(1) 根据给定的n个字符以及相应的权值构造一棵最优二叉树
(2) 二叉树除了根结点以外,所有左边的分支标记 0 ,右边的分支标记为 1
(3) 对于每一种字符所对应的叶子结点找出到根结点的路径,则从根结点到此叶子结点路径上各分支字符组成的二进制数字串即为该字符的二进制前缀编码.
-Huffman prefix tree design 2-band coding method is as follows. (1) According to the given n characters and the corresponding optimal weights of a binary tree structure (2) binary tree except root node, all branch of the left marker 0, the right side of the branch marked as 1 (3) for each character corresponding to the leaf node to the root node to find the path from the root node to this leaf node of the branch path characters composed of binary digit string is the character encoding of the binary prefix.

Description: 最不 重 要 位(LSB)方法DO是将秘密数据(水印数据)嵌入到载体数据中最简单的一种方法，它是在时域里隐藏数据。任何的秘密数据都可以看作是一串二进制位流，而音频文件的每一个采样数据也是以二进制数来表示。这样，可以将部分采样值的最不重要位用代表秘密数据的二进制位替换掉，以达到在音频信号中嵌入秘密数据的目的。-The most significant bits (LSB) method of DO is the secret data (watermark data) embedded into the data in the simplest way, which is hidden data in the time domain. Any secret data can be viewed as a string of binary bit stream, and audio files of data for each sample is expressed in binary numbers. This value can be part of the sample with the least bit representative of the secret bits of data and replace the audio signal to achieve the purpose of embedding the secret data. Platform: |
