车辆道路谱时域频域平均功率谱分析matlab程序(Road vehicles, the average spectrum of time domain frequency domain power spectral analysis matlab program)

能测定蓝底白字的车牌，图片格式要设定为640*480的jpg。(It can recognize the vehicle number plate with white number on a blue background.)

说明：  Matlab贝叶斯分类器+(Bayers)程序(Matlab Bayesian classifier+ (Bayers) program)

计算扰动后的T检验Matlab程序，对原始数据进行扰动以分析扰动后的变量是否具有显著性(Perturbation calculation of Matlab after the T-test procedure, the original data to analyze the disturbance after disturbance variables are significant)

mip线性混合整数规划工具箱，比较实用，可以实现整数线性规划。(mip linear mixed integer programming toolkit, more practical)

说明：  分两层取两个不同速度的绕射扫描叠加偏移方法(migration code based on diffraction stack)

A very useful matlab package on super-resolution.(Matlab package on super-reso lution.)

计算给定函数的全局最优位置以及优化极值，并输出结果(Calculating a given function and optimize global best position extremes, and outputs the result)

运用TDOA进行定位的Matlab源代码，(Using TDOA location of the Matlab source code, )

因为傅立叶变换对应的是无限信号,信号经过分帧后变成有限信号,分帧的信号再进行傅立叶变换后,高频部分将有 泄露 ,所以要加窗. 窗函数的拼谱都是在某高频部分截止,所以每帧信号加窗后的傅立叶变化,频谱基本 泄露 (Because Fourier transform corresponding is infinite signals, signals after framing become limited, framing signal again after Fourier transform, the high frequency part will have leaked , so to add window. Window function spell spectrum are in a high frequency part of the globe, so each frame and window after Fourier transform, signal spectrum basic leak )
