摘    要:提出了一种汽车牌照的自动识别算法:先对图象进行直方图均衡,平滑去噪,二值化预处理,再根据车牌上文字变化特点快速,准确地从复杂背景中分割车牌最后采用投影-变换系数法取汉字,英文和阿拉伯数字的不同维数的特征,送到相应的BP神经网络中进行识别,较好地解决了汽车牌照的自动畜产

关 键 词:特征识别  模式识别  车牌定位  车牌识别

Abstract:Automatic recognition algorithm of a car license plate (CLP) is proposed.First the image with a car must be preprocessed.Then based on the steady of the characters on the CLP,a new method to locate CLP in a complex background is presented accurately and rapidly.Finally,the project changing method is used to extract vectors of different dimension for Chinese character, English and Arab alphabet.The recognition result by BP network shows that owing to the high speed and strong recognition ability of BP network, the automatic recognition problem of the CLP is solved very well.
Keywords:character recognition  pattern recognition  CLP location  CLP recognition  BP network
