基于小波包分解的语音去噪，根据熵谱概率密度函数估计阈值，去除实际环境噪声。(Based on wavelet packet decomposition of the voice de-noising, in accordance with spectral entropy probability density function estimated threshold, the actual removal of environmental noise.)

matlab code you can run it and its detail has been in to the file.for compiling you need octave for linux or matlab program to run it.

仿真采用Erlang B模型，此仿真考虑用户呼叫时，若无空闲信道则被阻塞的情况。对话务量和阻塞率进行仿真(Simulation using Erlang B model, consider the user calls this simulation, the channel was idle without congestion. Blocking rate for traffic simulation )

noisegen.m：生成白噪声并按照指定信噪比对语音进行加噪； add_noisem.m：使用输入的噪音按照指定信噪比对语音进加噪； SNR_singlech.m：输入纯净语音和加噪后的语音，计算其信噪比； my_add_noise.m：调用上述函数进行加噪操作；(noisegen.m: white noise generated by the specified signal to noise ratio of the speech plus noise add_noisem.m: use the specified input noise into the signal to noise ratio of the speech plus noise SNR_singlech.m: pure voice input and processing after the noise voice, calculate the signal to noise ratio my_add_noise.m: call the above functions plus noise operation )

用matlab计算两个图像的匹配率，适合初学者学习(Calculated using matlab matching rate of two images, suitable for beginners to learn)

Geddes,肤色分割，数字滤波器，Otsu-最大类间方差，非线性映射所产生的混沌序列(Geddes, color segmentation, digital filter, Otsu- Otsu, nonlinear mappings from the chaotic sequence)

its a matlab discription of varius digitl filers both in special and frequency domain. very useful for beginners.

这个是一个函数逼近算法源代码，希望对大家有帮助，请下载哦，(This is a function approximation algorithm for the source code, I hope all of you help, please download Oh,)

implements the secant method for solving an equation f(x) = 0.
