Orthogonal-Matching-Pursuit

说明：  本系统运用LZ77字典算法、懒惰匹配算法和Huffman编码算法，使用Java语言在Jbuilder2006环境下设计了使用GZIP算法对文件压缩与解压缩的实现程序。用户可以根据自己的需求，使用此程序方便地对文件进行压缩或者解压缩操作。(This system uses LZ77 dictionary algorithm, lazy matching algorithm and Huffman coding algorithm, and uses Java language to design the implementation program of gzip algorithm for file compression and decompression under the environment of JBuilder 2006. Users can use this program to compress or decompress files conveniently according to their own needs.)

压缩与解压缩类；压缩文件至.zip包内，增加文件至.zip包内，及解压缩相关操作。(zip and unzip。)

说明：  这是相关编码的标准和实现，是密码学的和数据压缩的基础。(This is the relevant coding standards and implementation, is cryptography and data compression basis.)

实现成绩表的输出，实现成绩表的输出，实现成绩表的输出，实现成绩表的输出，实现成绩表的输出，实现成绩表的输出(score print)

CONTOURLET去噪。添加了高斯噪声很好的实现了图像的多尺度分解下的去噪与重建。实现了多尺度分解的子带去噪。(CONTOURLET denoise .this is denoise program. my english is poor!)

传统游程编码，并且又对游程编码进行了一定程度的改进。(The traditional run-length coding has improved it to some extent.)

说明：  基于FFT和DWT变换的压缩感知，比较不同稀疏基下CS重构算法的性能(CS based on FFT and DWT)

RLPack is a software that gives you the power to compress your executables and dynamic link libraries in a way that keeps them small and has no effect on compressed file functionality. Further more RLPack protects your files from modification and has several protection options which help protecting your files from being changed or cracked. But compression and protection does not stop there. RLPack with iBox module can pack your dynamic link libraries and place them inside the main executable so they can not be modified. They are extracted directly to memory (or optionally to disk) hiding their presence and enabling you to keep your dynamic link libraries safe from being used by third party programs or users.

对输入的字符进行哈弗曼编码，生成编码表，计算压缩比等(haffman tree)

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.)
