我们确定数字滤波器的幅度函数并画出幅度函数图。(We define digital filter amplitude function and draw the amplitude function diagram.)

Matlab实现的基于颜色分隔的人脸人眼检测与定位及识别算法源代码(Matlab implementation based on the color-separated face and eye detection and location recognition algorithm source code)

实用化工计算机模拟：MATLAB在化学工程中的应用 附录光盘程序(Computer Simulation of practical chemical procedures Appendix CD)

说明：  介绍数字信号处理及其matlab 语言实现，包括滤波器设计等(On digital signal processing and matlab language, including the filter design and so on)

变步长自然梯度算法实现盲源分离，后面还有动量项自然梯度算法(Variable step-size natural gradient algorithm for blind source separation)

拨号按键识别GUI界面程序，原理采用DTMF，本程序随意按下六位数字，当按下第七位的时候屏幕清空，点击解析，结果将显示在文本框中，并有相应的声音。(GUI interface dial buttons identification procedures, principles using DTMF, this program free to press the six figures, when you press the seventh, when the screen is empty, click the analytical results will be displayed in the text box, and a corresponding sound.)

说明：  这是一个音频时域信号的盲源分离的Matlab程序，效果不错。(This is an audio signal in time domain blind source separation of the Matlab program, the effect is good.)

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.)

利用TM图像，反演各种海面环境因子，例如海面温度，泥沙含量，叶绿素a等。(TM image using the inversion of various sea environmental factors, such as sea surface temperature, sediment content, chlorophyll a and so on.)
