数字图像处理project4， 人脸检测，利用matlab自带工具箱(Digital image processing project4, face detection, built using matlab toolbox)

车辆信号被动式红外信号的滤波以及能量分析(Vehicle passive infrared signal filtering and signal energy analysis)

最速下降法、DFP法问题解最优化问题，工程优化，matlab(The steepest descent method, DFP method solution optimization problem, engineering optimization and matlab )

1.升余弦窗首尾8点数据值:12bit-> 1-1RAM_OUT_CNT_RN10 formal 采用移位相加的方式来取代相乘运算，节省资源。 (1 liter inclusive 8:00 cosine window data values​ ​ : 12bit-> 1-1RAM_OUT_CNT_RN10 formal using shift and add a way to replace multiplication, save resources.)

用小程序模拟实现文字飞行的效果，通过改变字体的大小和显示位置(Simulation with a small procedure to achieve the effect of flying text, by changing the font size and display position)

本实验隶属现代数字信号处理，涉及到谱估计和谱分解，对学习数字信号的现代处理方法帮组很大。系统辨识实验实现：输入为功率为1（方差为1）的白噪声信号，通过一个线性移不变（LSI）系统，采用功率谱分析方法实现系统辨识对一个LSI系统进行辨识,并比较最后辨识出的系统与原系统的差别，分别显示出来。 (Experimental realization of system identification: input power of 1 (variance 1) of the white noise signal through a linear shift invariant (LSI) system, using power spectral analysis method of system identification of an LSI system identification, and compare the final system and identify the difference between the original system, respectively, is displayed.)

用total variance（TV）算法对图像进行去噪，具体参数代码里有(With the total variance (TV) image denoising algorithm, the specific parameters in the code there)

用MATLAB编写的BP 程序。。。希望可以对大家有所帮助(BP program)
