中值滤波和均值滤波程序，经常用于数字图像处理中，是基本的图像预处理程序(medium filter and average filter program,it is often used in image progress )

the code is based on lsb matching revisited technique the new technique available to the user for steganography. that provide high accuracy

说明：  扑克识别代码，能识别扑克的数字和黑红梅方等颜色。(Poker identification code, to identify the number of poker and black color Hongmei Fang.)

基于功率谱相减的语音消噪增强法程序，采用硬阈值法(Power spectrum subtraction based speech denoising Enhancement Act program, using hard-threshold)

波束空间的MUSIC算法，在阵元误差校正和ＤＯＡ估计时很实用～～(Beam space MUSIC algorithm, the array element error correction and DOA estimates very practical ~ ~)

说明：  QC-LDPC的主程序，IEEE802.16e标准，考察迭代次数对误码率的影响(Various encoding and decoding methods of LDPC)

对无线通信信道中的瑞利衰落进行MATLAB仿真(of wireless communications channel for the Rayleigh fading MATLAB simulation)

基于遗传算法摩擦模型参数辨识的PID控制，matlab程序(friction model parameter identification of PID control, Matlab procedures)

This Matlab code is written by me and its purpose is for car plate detection by using labeling and morphological operation. Its very fast and simple. for working on specific database it needs to change structural elements of morphological operation and also the area of white pixels in labeling part. for any information you can contact with me through my email.

使用迭代式阈值算法来提高图像对比度。可以指定某个色阶作为阈值，所有比阈值亮的像素转换为白色；而所有比阈值暗的像素转换为黑色。 (The use of iterative threshold algorithm to enhance image contrast. You can specify a color scale as the threshold, all pixels lighter than the threshold into white and all pixels darker than the threshold value is converted to black.)
