摘　　要：文章介绍了利用车牌的纹理特征和区域形状特征检测车牌区域情况。为提高区域检测的正确性,利用新的改进的主动轮廓模型,利用先验知识确定精确的车牌边界。在精确的车牌区域中切割出车牌中的单个字符,最后利用支持矢量机对字符进行分类识别。This paper presents a license plate recognition method to extract the initial region by utilizing the texture character and region shape character of a plate. To improve the region extraction accuracy, the paper uses newly-improved active contour models and a priori knowledge to decide accurate plate border. Because of the accuracy of the plate region extraction, the character can be extracted exactly from the plate region. Finally, support vector machine is used to recognize the characters.
