边缘检测

Based on the theories of the first two chapters, chapter 5 introduces the theoretical foundation and method of the software design of the license plate recognition system in detail. In this system, a license plate is fixed in a position and cut apart by verge examination based on the differential operator and threshold algorithm. Then outline method and projection method are used as methods of characteristic extracting, lastly neural network is used as a method to recognition the single character.

第五章是在前两章的理论基础上，详细介绍了车牌识别系统软件设计的实现方法和实验结果，应用图像分割的理论对车牌进行边缘检测和提取，利用轮廓和投影的方法提取字符的特征，最后用神经网络的方法对所得字符进行识别。
