JPEG2000压缩图像质量评价代码，不需要原参考图像，很准确(the image quality assessment method, without the reference image. )

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.)

上载了蜂窝网3种经典的无线定位算法，即fang算法、chan算法、taylor算法，大家相互交流学习。(Uploaded three kinds of classical cellular wireless location algorithm, that is, fang algorithm, chan algorithm, taylor algorithm, we share their knowledge with each other.)

说明：  利用哈夫曼树对简单文件进行压缩和解压缩，对数据的压缩集成(Compression and Decompression of Simple Files Using Huffman Tree)

图像压缩的Huffman编码与解码,matlab源代码(Image compression Huffman encoding and decoding, matlab source code)

计算多重积分是蒙特卡罗方法的重要应用领域之一。本章着重介绍计算定积分的蒙特卡罗方法的各种基本技巧，而这些技巧在粒子输运问题中也是适用的(Calculation of multiple points is an important application of the Monte Carlo method, one of the areas. This chapter focuses on calculation of definite integral of the Monte Carlo method, a variety of basic skills, and these skills in particle transport problems are also applicable to)

jepg压缩的matlab代码，采用哈夫曼编码，dct变换(jepg compression Matlab code, using Huffman coding, transform Extra)

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!)

非常好的视频压缩filter,可以实现mpeg2 mpeg1的视频压缩，用户可以自己选择码率(very good video compression filter can achieve mpeg1 mpeg2 video compression, Users can choose Rate)
