用c语言编写的哈夫曼压缩解压-prepared by the Huffman compression decompression

采用C++编写的已经封装好的lzw压缩算法，对于常规文件压缩而言，这个压缩算法的速度还是比较不错的，也可以用于嵌入式平台下使用-The use of C++ package has been prepared lzw good compression algorithm, the conventional file compression, this compression algorithm is quite good speed, can also be used for embedded platforms

游程编码的主要部分，对简单的变化缓慢，重复出现的数据有很好的压缩效果-Run-length coding of the main part of a simple change in the slow, repeated data compression has a very good effect

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.

采用c语言对8**8图像进行离散傅立叶变换，实现对图像压缩处理-to eight images** 8 discrete Fourier transform, to achieve Image Compression

【文本与二值图像的游程】1. 文本游程压缩的原理 对重复字段采用3符号标识法：(1) 重复提示符,比如@,#等；(2) 游程长度参数或重复次数,若用一个字节表示,最大长度可为255个重复字；(3) 重复字符。以上三部分合称为重复因子。可见要获得压缩效益，重复字符应在3个以上。2. 图像游程压缩的原理 对于二值图像，原始数据为零一矩阵，压缩时逐行处理该矩阵：(1) 连续n个1，表示为+n；(2) 连续n个0，表示为-n。-text and binary image-- an outbound trip. Yu Cheng text compression principle on repeated field using three symbols logo Act : (a) repeat prompt, such as @,#, etc.; (2) Run-length parameters, or the number of repeat, if using a byte, the largest the length of 255 to repeat the word; (3) repeat characters. More than three as part of a repeat factor. Visibility to gain compression efficiency, duplication of characters in three more. 2. Run-image compression for the principle of two binary images, a zero original data matrix, progressive compression deal with the matrix : (1) n a row, n; (2) consecutive n 0, expressed as-n.
