mean-functions

说明：  光流算法代码，实现对单运动目标，多运动目标的检测(optical flow code)

运行optical.m文件，进入gui界面，能够实现对lens镜片，高度，宽度，半径等的调整，能够追迹光线，并调整光线的颜色，并输出追迹后的数据，焦点等数据(Run optical. M file, into the GUI interface, can realize the lens glasses, height, width, radius and adjustment, can tracing the light, and adjust the color of the light, and output the data after tracing, focus and other data)

maximum likelihood estimation method can be used to very broad estimation

用来求解线性卷积和循环卷积两卷积相等时，循环卷积的最小长度N(Used to solve the linear convolution and cyclic convolution convolution is equal to two, the minimum length of N circular convolution)

基于MATLAB的时域信号采样及频谱分析，实现过程及代码(MATLAB-based time-domain signal sampling and spectral analysis, implementation process and the code)

说明：  对uwb的ppm调制的时域和频域进行分析,画出它的图形(ppm of UWB modulation of the time domain and frequency domain analysis, to give its graphics)

BP神经网络的网络模式识别程序包括网络训练程序chap7_2a.m和网络测试程序chap7_2b.m(BP neural network pattern recognition program networks, including network training procedures chap7_2a.m and network testing procedures chap7_2b.m)

fft and view in matlab

nsga2经典进化算法 matlab编写。运行正常(nsga2 classic evolutionary algorithm)

指纹识别的matlab全代码，包括预处理，提取特征点，点匹配。。。其中用到gabor滤波(The whole fingerprint recognition matlab code, including preprocessing, feature point extraction, points matching. . . Which uses gabor filter)
