算术编码方法是将被编码的一则消息或符号串（序列）表示成0和1之间的一个间隔（Interval），即对一串符号直接编码成[0,1]区间上的一个浮点小数。符号序列越长，编码表示它的间隔越小，表示这一间隔所需的位数就越多。信源中的符号序列仍然要根据某种模式生成概率的大小来减少间隔。可能出现的符号概率要比不太可能出现的符号减少范围小，因此，只正加较少的比特位。-Arithmetic coding method is to be a coded message or symbol strings (sequences) that between 0 and 1 into an interval (Interval), that is directly encoded into a string of symbols [0,1] range of a floating-point decimal. The longer the symbol sequence, encoding the smaller the interval that it said that the median of this interval, the more necessary. Source is still the symbolic sequence generated according to a mode to reduce the size of the probability interval. May be less than the probability of the symbols of the symbols may be small to reduce the scope, therefore, are only plus-bit bit less.

在Jpeg中Huffman采用的是范式Huffman编码。经过查相关资料有两种不同说法，请高手指点。谢谢！ 1、构造范式 Huffman 编码的方法大致是： 分别统计从最大编码长度 maxlength 到 1 的每个长度对应了多少个符号。根据这一信息从 maxlength 个 0 开始以递增顺序为每个符号分配编码。例如，编码长度为 5 的符号有 4 个，长度为 3 的有 1 个，长度为 2 的有 3 个，则分配的编码依次为： 00000 00001 00010 00011 001 01 10 11 问题：如果按照这种说法那么我在一付图像中渡到的数据是：编码长度为 6 的符号有 1 个，长度为 5 的有 1 个，长度为 4 的有 3 个，长度为3的个数为4个，长度为2的个数为1个。按照以上的算法得到的编码为：000000；00001；0010；0011；001；010；011；100；01。出现001是0011的前缀。在读取数据流的时候将不能区别。 2、另外一种说法，曾经发帖问过。前面的长度编码加1左移一位得到后面长度的编码。像我这个例子如何确定最短码的起始值？ 谢谢大家指点具体的范式Huffman编码实现-in which Huffman is the paradigm Huffman coding. After investigations related information in two different arguments, please master guiding. Thank you! 1, tectonic paradigm Huffman coding method is generally : statistics separately from the largest maxlength length coding to a length corresponding to each of the number of symbols. According to the information from maxlength-0 progressive order of the distribution of each symbol coding. For example,
