区别去传统的傅里叶变换，对于非平稳信号而言，分数傅里叶变换是一个较好的方法，本程序实现了分数傅里叶变化对LPF类信号的估计。具有较高的学习价值(Different from the traditional Fourier transform, for non-stationary signals, fractional Fourier transform is a better method, this program implements the fractional Fourier transform to estimate the class LPF signal. It has higher learning value)

本文重点研究了面积法对车流量进行统计。在研究算法过程中主要用到了车辆图像检测相关的灰度化、滤波、图像增强、锐化等图像处理基础知识，并将这些知识的算法进行了比较研究。进而用到了阈值分割、边缘检测、以及形态学操作等图像分割技术以及车辆的检测和提取算法。最后设计了一种实时可靠的统计算法。(This paper focuses on the area method for traffic statistics. In the study of algorithms used in the vehicle during the main test-related gray scale image, filtering, image enhancement, sharpening and other image processing basics and knowledge of the algorithms were compared. Then use a threshold segmentation, edge detection, and morphological operations such as image segmentation, and vehicle detection and extraction algorithms. The final design of a real-time reliable statistical algorithms.)
