此为基于二代提升小波的阈值压缩算法源码,其中可以设置小波变换的分解层数,使用的小波名称,及各层阈值设置计算公式中的参数。并将低频系数转化为十六进制,方便在其上进一步压缩,如采用Huffman压缩等,程序思路清楚,附有完整的注释,可以使用多种小波,并且很好得体现了二代小波的思想,对于初学小波者帮助很大。-based on the second generation of this upgrade wavelet compression algorithm threshold source, which can set wavelet transform decomposition level, the use of wavelet name, threshold levels and set the formula for calculating the parameters. And low-frequency coefficients into hexadecimal facilitate its further compression, such as the Huffman compression. procedures ideas clearly, with the integrity of the Notes, you can use a variety of wavelet, and reflected very well in the second generation wavelet thinking, For beginners who wavelet of great help.

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,
