【摘要】 字符分割是车牌照自动识别系统中的关键步骤,通过对比3种车牌字符的分割方法,即水平投影法、模板匹配法、聚类分析法,提出了一些新的观点。经过对不同背景、光照条件下采集到的车辆图像进行实验,可以较好地解决在复杂背景条件下车牌字符分割的问题。更多还原

【Abstract】 Character segmentation is the key component of the automatic vehicle license recognition system.This paper studied three methods to segment the characters of license plate:level projection method,template matching method and clustering analysis,which could successfully solves the problem of the characters’ segmentation under complex background conditions.The performance of the system was investigated on many real car images with complex background captured under various illumination conditions.We also discuss the characteristics of these methods.更多还原
