The main researches about Chinese character recognition of vehicle license plate and its corresponding technique in this paper are as follows:(1) The pre-processing for image is essential before character recognition. This paper firstly uses the experience knowledge to give a roughly orientation,then set a carefully orientation based on Otsu arithmetic,finally get the whole clear license plate.In order to solve the problem of character extraction,the fly-back method is put forward:the experience knowledge is made the best of.(2) An algorithm of feature extraction from grayscale image based on optimization Gabor filters is proposed.

本文针对车牌汉字识别及相关技术进行研究，主要工作包括：(1)在对车牌汉字进行识别前需要进行必要的预处理工作，我们首先运用车牌的先验知识进行粗定位，然后采用Otsu阈值二值化方法等进行快速鲁棒的车牌区域细定位，获得完整、清晰的车牌轮廓，并采用回扫式字符切割方法，充分利用了车牌字符固有的特点准确找到各个字符的分割点，为特征提取奠定了基础；(2)提出一种优化的Gabor滤波器特征提取算法直接对灰度图像进行特征提取。

When I write "the history of Chinese folk paper-cut" of the period, civil paper-cut has given me the same enjoyment of the United States.

This paper use Monte Carlo method in Excel to dynamically simulate the service status and waiting time of university dinning room windows. This method based on "random number" is usually used to solve practical problems with complicate probability distribution. This paper simulates one window and two windows of a dinning room separately. Through 1000 simulations and statistic analysis to get conclusions, thus bring up reference frame to decision maker.
