| 摘 要： | 汽车牌照的识别在交通管理体系中占着非常重要的地位，而在进行汽车牌照自动识别的过程中，应用一个恰当的阈值对图像进行二值化处理是整个识别过程的基础，适当的阈值会减轻后续工作量。介绍了几种阈值选定办法，并在大津法的基础上针对车牌这种特殊图像的识别作了一点改进。

| Abstract: | The license plate recognition(LPR) is occupying the extremely important status in the traffic control system,but in the process of license plate automatic recognition,applying an appropriate threshold value to carry on binaryzation processing to the image is the base of recognition process,the suitable threshold value can reduce the following work.This article introduces several threshold value selection means,and have made an improvement on the basis of OTSU method in view of car license. |
