matlab 傅里叶变换

伪随机码或称PN码，是扩频通信中不可缺少的一种序列。扩频通信，简单的说来就是通过一组相关性很强的伪随机序列，使原有的信号按照伪随机序列的特性出现。(Said pseudo-random code or PN code, spread spectrum communication is an indispensable sequence. Spectrum, simple to say is highly relevant by a group of pseudo-random sequence, so that the original signal in accordance with the characteristics of pseudo-random sequence appears.)

本程序是应用matlab语言提取图像的不变矩输出结果。这是提取经典的七个不变矩的值，速度很快(this program is the application of Matlab language from the moment invariants image output. This is the classic seven from the same value of the moment, very fast)

说明：  用MATLAB编写的求曲线拟合的程序，希望大家分享一下。我是新来的。(Prepared using MATLAB for curve fitting process, I hope to share with Members. I was new.)

在约束感兴趣频带的条件下，运用二阶锥规划方法设计二维FIR滤波器，(Designs an 2-D FIR filter with given desired frequency response H_des(w1,w2) using SOCP)

本程序主要采取结构体进行编程，对帧中运动车辆进行跟踪，一个车一个标号，标号自增1.(The main structure of this program is programmed to take on the frame to track moving vehicles, a car of a label, label increment 1.)
