从整个符号序列出发，根据各信源序列的概率将信源序列映射到[0,1) 区间上，然后选取区间内的一点（也就是一个二进制的小数）来表示信源序列。
From the entire sequence of symbols, the source sequence is mapped to the interval [0,1] according to the probability of each source sequence, and then a point (that is, a binary fraction) in the interval is selected to represent the source sequence. (2017-09-19, matlab, 9KB, 下载5次)

费诺编码也是一种常见的信源编码方法。信源符号以概率递减的次序排列进来,将排列好的信源符号划分为两大组,使第组的概率和近于相同,并各赋于一个二元码符号”0”和”1”.然后,将每一大组的信源符号再分成两组,使同一组的两个小组的概率和近于相同,并又分别赋予一个二元码符号.依次下去,直至每一个小组只剩下一个信源符号为止.这样,信源符号所对应的码符号序列则为编得的码字.
Fenno coding is also a common source coding methods. The source symbols come in order of decreasing probability, the source symbols aligned into two groups, the first group and near the same probability, and assigns a binary code of the symbol "0" and "1" then, a large group of each source symbol and then divided into two groups, so that the same group of two teams and nearly the same probability, and they were given a binary code symbol sequence continues until each team only until the next source symbols so, the source code symbols corresponding to the symbol sequence obtained was compiled code word.

由于目前数字通信中一般都使用二进制符号，因此二进制的Huffman编码技术最为普遍，其编码步骤如下：
1、将信源符号按概率从大到小进行排列；
2、给两个概率最小的信源符号各分配一个码元“0”和“1”，然后将这两个信源符号合并成一个新符号，并用这两个最小的概率之和作为新符号的概率，结果得到一个只有（n-1）个信源符号的新信源（假设原来所需编码的符号数为n），称为信源的第一次缩减信源S1；
3、将缩减信源S1的符号仍按概率从大到小的顺序进行排列，重复步骤2，得到只含（n-2）个符号的缩减信源S2；
4、重复上述步骤，直至缩减信源只剩两个符号为止，此时所剩两个符号的概率之和必为1，将这两个符号各分配一个码元“0”和“1”后，从最后一级缩减信源开始，依编码路径向前返回，就得到各信源符号所对应的Huffman码字。
Due to the current digital communication in general use binary symbols, so the Huffman coding of binary is the most common, the encoding procedure is as follows:1, the source symbols according to the probability from big to small order 2, to the two smallest source symbols of each is assigned a code "0" and "1", then the two source symbols are combined into a new symbol, and the two smallest probability and probability as a new symbol, the result is a only (n-1) new source source symbols (the original hypothesis number symbols required coding for n), called the first cut the source S1 source 3, cut the source S1 symbols according to probability from big to small order of rank, repeat steps 2, got only containing (n-2) a symbolic reduction source S2 4, repeat the above steps, until reduced source only two symbols, the remaining two symbol probability and will be 1, these two symbols each assigned a symbol "0" and "1", from the beginning of last stage reduced source, according to code pa (2013-05-31, Visual C++, 1KB, 下载2次)

此代码是在保持信噪比的情况下，进一步提高了压缩比。灰度级的减少，势必会降低信噪比，但因为是处以比较小的整数，并没有引起熵值的剧烈变化，编码后信噪比基本不变。
This code is to maintain the signal to noise ratio of the case, to further improve the compression ratio. Gray-scale reduction, will inevitably reduce the signal to noise ratio, but because it is punishable by a relatively small integer, and did not cause dramatic changes in entropy, the encoded signal to noise ratio remains unchanged.
