呃，就是用赫夫曼算法写的压缩解压程序。非常粗糙，只能压缩英文文章。因为里面的字符概率是基于自然语言的，源代码之类的没法压缩。而且会抛弃最后几个字母，嘿嘿。为了交作业，没有好好写。改一下下应该能挺好的。压缩比能到60 吧(Uh, is to use Huffman compression decompression algorithm written procedures. Very rough, only compress English articles. Because there is the probability of characters based on natural language, the source code and the like can not compressed. And will abandon the last few letters, hehe. For homework, not properly written. The following should be able to change it quite good. Compression ratio to 60 of it can be)

说明：  自适应信号处理的理论和技术经过40多年的发展和完善，已逐渐成为人们常用的语音去噪技术．并通过实例介绍了基于Matlab的RLS自适应语音噪声对消系统的设计与实现．(After more than 40 years of development and improvement, the theory and technology of adaptive signal processing have gradually become a common speech denoising technology. The design and implementation of RLS adaptive speech noise cancellation system based on Matlab are introduced through an exampl)

哈夫曼编码译码系统，设置发送者和接受者两个功能， 发送者的功能包括： ①输入待传送的字符信息； ②统计字符信息中出现的字符种类数和各字符出现的次数（频率）； ②根据字符的种类数和各自出现的次数建立哈夫曼树； ③利用以上哈夫曼树求出各字符的哈夫曼编码； ④将字符信息转换成对应的编码信息进行传送。 接受者的功能包括： ①接收发送者传送来的编码信息； ②利用上述哈夫曼树对编码信息进行翻译，即将编码信息还原成发送前的字符信息。 (Huffman decoding system, set the sender and the recipient of two functions, the sender' s features include: (1) input to be transmitted character information ② statistical character information, the number of types of characters and characters the number of occurrences (frequency create a Huffman tree) ② According to the number of types of characters and their respective number of occurrences ③ use the Huffman tree to find the characters Huffman coding ④ character information into the corresponding coding information for delivery. The recipient of the features include: (1) to receive the coded information to the sender transmission ② above Huffman tree coded information to be translated, is about to coded information to restore the character information before sending.)

OOMP算法是压缩传感的一种算法，其对OMP算法进行改进，提高了正确率。(OOMP Compressed sensing algorithm is an algorithm to improve its OMP algorithm to improve the accuracy.)

说明：  一个简单的32位位图压缩算法，基本思想是，扫描像素点，后面有雷同的就记下重复次数。(A simple 32-bit bitmap compression algorithm, the basic idea is to scan pixel, behind identical repetitions on the record.)
