摘要
数学形态学具有速度快、方法简单等特点,使用数学形态学进行车牌的识别.通过预处理和阈值分割算法后,主要利用形态学腐蚀运算进行车牌边缘检测和识别,该方法检测物体的边缘宽度仅为一个像素,定位精度高.通过与传统的边缘检测算子比较,再选择合适的结构元对车牌识别,具有良好的识别结果.使用MAT-LAB7.0软件进行仿真,通过大量实验,证明该算法具有一定的实用性.
The features of Mathematical Morphology are quick and brief function and so on. The paper uses Mathematical Morphology for the vehicle license recognition. After the pretreatment and threshold values segmentation, the erosion operation of Morphology is to edge detection and recognition of the vehicle license. The way is going to detect only pixel of edge breadth of the object, so it is high position precision. Finally, the matlab 7.0 is used to simulate the images. A lot of experiments show that, the algorithm is of practicality.
