摘要
本文介绍了常用的几种边缘检测算子,不同的微分算子对不同边缘检测的敏感程度是不同的,因此对不同类型的边缘提取,应该采用对此类边缘敏感的算子进行边缘提取。针对车辆牌照自动识别,通过Matlab6.5进行了仿真研究,并比较和分析了这些算子的特点和作用,从中选出了合适的方法。
This paper presents a few operators based on edge detection.Sensitivity is different for different differential operators.so different types of edge detection must adopt corresponding sensitive operator.The Automatic Recognition of Automobile license plate is Simulated by Matlab 6.5, the characters and functions of the operators are compared and analysed, the suitable method have elected from it.
