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.

实现对字符的赫夫曼编码，译码，运用栈存储少量字符数据-Realize the characters Huffman encoding, decoding, using a small amount of character data storage stack

lzma算法实现，很经典包括c/c++/c#/java的实现-lzma algorithm, including classic c/c++/c#/java realization

huffman编码与解码的实现程序，内附编译及使用说明，很完善的程序，可以自由的输入字符集大小以及字符的权值。-huffman encoding and decoding the realization process, containing the compiler and use that, it is well established procedures, they can input character set size and weight of characters.

QccPackSPECK也是重要的嵌入式编码方法，在小波编码中具有重要应用。这个代码3d-speck也是应用于三维小波体数据压缩的代码。-QccPackSPECK is also an important embedded coder, which is vital in wavelet coding. this 3d-speck sourcecode is very useful for people who process 3d volume data

快速排序,快速排序是对冒泡排序的一种改进。它的基本思想是：通过一躺排序将要排序的数据分割成独立的两部分，其中一部分的所有数据都比另外一不部分的所有数据都要小，然后再按次方法对这两部分数据分别进行快速排序，整个排序过程可以递归进行，以此达到整个数据变成有序序列。-Quick Sort, Quick Sort Bubble Sort is an improvement. Its basic idea is: lying through one sorting to sort the data to be split into two independent parts, one part of all of the data than the other one is not part of the all the data should be small, and then meeting the two methods were part of the data quick sort, the entire sorting process can be recursive, and thus the entire data into an orderly sequence.
